1 Scope

NOTE This standard governs the design, fabrication, finishing, and installation of extruded aluminum entrance and storefront systems, the glass and insulating glass units glazed into them, the swing entrance doors integrated with them, and their perimeter anchorage and seals. (1.1)
1.2 The furnished work shall comprise the framing assembly, the glazing infill, the entrance door leaves and their hardware, the thermal barrier construction, the perimeter anchorage, and the sealed interfaces between the storefront perimeter and the adjoining construction.
NOTE Storefront elevations, mullion and door locations, transom and sidelight arrangement, glass type designations by lite, and hardware set assignments are established by the contract drawings and are not fixed by this standard. (1.3)
1.4 Storefront and entrance layout shall be as indicated on the contract documents.
1.5 The Contractor shall treat the storefront, its glazing, its doors, and its perimeter seals as one coordinated assembly and shall reconcile every performance criterion across those parts before fabrication is released.
NOTE Structural, thermal, water control, air control, egress, accessibility, and durability requirements are cross-coupled in a glazed aluminum assembly, so a change made to satisfy one of them routinely disturbs another. (1.6)
NOTE A deeper thermal barrier lowers the assembly U-factor and also changes the profile depth, which changes the anchor preparation and the door pocket dimension; a higher design pressure drives thicker glass, which raises unit weight and changes the closer size and hinge selection; a laminated inboard lite adds weight and thickness to every unit it appears in. (1.7)

1.8 Coordination with Adjacent Work

1.8.1 The Contractor shall coordinate hardware finish, keying, and access control preparation across entrance, storefront, and interior openings with Doors Frames And HardwareDoors, Frames, and HardwareResolves to the current adopted revision.sync/doors-frames-and-hardware.
1.8.2 The Contractor shall coordinate continuity of the building thermal envelope at the storefront head, jambs, and sill with Building Thermal InsulationBuilding Thermal InsulationResolves to the current adopted revision.sync/building-thermal-insulation.
1.8.3 The Contractor shall coordinate head flashing, sill pan flashing, end dams, and perimeter closures and counterflashing with Sheet Metal Flashing And TrimSheet Metal Flashing and TrimResolves to the current adopted revision.sync/sheet-metal-flashing-and-trim.
1.8.4 The Contractor shall coordinate continuity of the air control layer and the water resistive barrier across the storefront rough opening with the trades installing those layers in the adjoining wall.

4.2.2 The storefront mock-up requirement shall be as indicated in the datasheet.
Storefront Mock-Up Requirementselect

5 Performance Classification

5.1 Rated Performance Class and Grade

NOTE AAMA/WDMA/CSA 101/I.S.2/A440 classifies a fenestration product by a performance class letter paired with a performance grade number, written together as a class-grade designation. The class establishes the gateway test criteria the product must satisfy; the grade is the design pressure in psf at which the product was tested. (5.1.1)
5.1.2 The storefront and entrance system shall be tested, rated, and labeled in accordance with AAMA/WDMA/CSA 101/I.S.2/A440.
5.1.3 The rated performance class shall be as indicated in the datasheet.
Rated Performance Classselect
R
LC
CW
AW
5.1.4 The rated performance grade shall be not less than the design wind pressure established by the structural drawings for the storefront's exposure and elevation.

5.2 Design Wind Pressure

NOTE Design wind pressure is established by the building code wind load determination for the project location, building height, exposure category, and the storefront's position on the facade, and it differs between the inward-acting and outward-acting directions at the same location. (5.2.1)
5.2.2 The inward-acting design wind pressure shall be as indicated in the datasheet.

Per drawings — structural drawings (deferred by default)
5.2.4 Framing, glass, and anchorage shall be designed for the greater of the inward-acting and outward-acting design wind pressures at each location, applied in each direction independently.

5.3 Structural Load Resistance

5.3.1 The framing system shall withstand the design wind pressure in both directions without glass breakage, anchor failure, permanent deformation, or loss of the air or water seal.
5.3.2 Structural performance shall be verified by test in accordance with ASTM E330 at 1.5 times the design wind pressure applied for 10 seconds in each direction.
5.3.3 Permanent deformation of any framing member after the structural overload test shall not exceed 0.2 percent of the member span.
5.3.4 Glass thickness and heat treatment shall be selected in accordance with ASTM E1300 for the design wind pressure, lite dimensions, support condition, and unit make-up at each lite.

5.4 Framing Deflection Limits

NOTE Excessive framing deflection under wind load relieves gasket compression at the glazing pocket, opens the perimeter seal, and transfers load into the glass edge. Two bounds are customarily applied together because a span ratio alone permits large absolute movement on a long member. (5.4.1)
5.4.2 Framing member deflection normal to the plane of the wall under the design wind pressure shall not exceed the span ratio indicated in the datasheet.

5.4.4 Deflection of a framing member parallel to the plane of the glass under superimposed dead load shall not reduce the glass edge clearance below the value published by the framing manufacturer for the glazing pocket, and shall not exceed 1/8 in.

6 Air Infiltration

NOTE An air leakage limit is meaningless without the pressure differential at which it is measured. US energy codes rate storefront glazing and commercial glazed swinging entrance doors at 1.57 psf, while project specifications for commercial storefront commonly require the same rate to be demonstrated at 6.24 psf, which is the substantially more demanding of the two. (6.1)
6.2 Air infiltration shall be tested in accordance with ASTM E283 at the pressure differential indicated in the datasheet.

6.4 Air leakage through a swing entrance door, measured over the door leaf area, shall not exceed the rate indicated in the datasheet.
Air Leakage Limit — Swing Entrance Doorrange
cfm/ft²
0.30.50.7511.5
NOTE A swing entrance door leaks more air than the fixed framing around it because the leaf needs operating clearance at every edge, and the seal at that clearance is a compressed or wiping contact rather than a captured gasket. Where the leakage rate must approach that of the fixed framing, full-perimeter compression weatherstripping and a drop seal at the sill are the mechanisms available, and a vestibule removes the exterior pressure differential from one leaf entirely. (6.5)

7 Water Penetration Resistance

7.1 Static water penetration resistance shall be tested in accordance with ASTM E331 at the test pressure indicated in the datasheet.
Water Penetration Resistance Test Pressurerange
psf
2.8656.24810121520
NOTE AAMA/WDMA/CSA 101/I.S.2/A440 derives the water test pressure as a fraction of the design wind pressure subject to a floor and a ceiling, so on most projects the value in the datasheet follows from the design pressure rather than being chosen independently. (7.2)
7.3 Where cyclic water penetration testing is required by the datasheet, it shall be performed in accordance with ASTM E547 at the same test pressure.
7.4 No water shall pass beyond the innermost plane of the framing during the water penetration test period.
7.5 Water that enters the glazing pocket or an internal framing cavity shall be collected and drained to the exterior, and shall not reach the interior face of the framing.
NOTE Controlled leakage into a drained and weeped cavity is the design intent of a captured aluminum glazing system, so a test criterion written as no water entering the system at all would fail a correctly built assembly. The criterion is that no water passes the interior plane. (7.6)

8 Thermal and Solar Performance

NOTE Whole-product ratings and center-of-glass ratings are not interchangeable. A center-of-glass U-factor omits the frame and the glass edge, which are the least insulating parts of the assembly, so it always reads better than the assembly the project actually receives. (8.1)
8.2 Thermal transmittance, solar heat gain coefficient, and visible transmittance shall be established for the complete fenestration product, including framing, in accordance with NFRC 100 and NFRC 200.
8.3 Component-level or center-of-glass values shall not be substituted for whole-product ratings where the energy code compliance path requires certified whole-product ratings.
8.4 The maximum whole-product thermal transmittance shall be as indicated in the datasheet.

VT
0.10.20.30.40.50.60.70.8
Per drawings — energy compliance documentation (deferred by default)
NOTE Solar heat gain coefficient and visible transmittance both fall as a coating is made more solar-selective, and the ratio between them is bounded by the coating chemistry available. A target pair that is unreachable by any coated unit forces a change to one of the two targets, so the pair is checked against candidate unit make-ups before the glass is released. (8.7)
8.8 The Contractor shall confirm through the insulating glass unit submittal that the U-factor, solar heat gain coefficient, and visible transmittance targets are met simultaneously by the proposed unit make-up, and shall report any target that cannot be met to the Engineer of Record before the glass is fabricated.

9 Condensation Resistance

NOTE Two US condensation metrics are in use and their values are not interchangeable. AAMA 1503 reports a condensation resistance factor from a guarded hot box test of the assembly; NFRC 500 reports a condensation resistance value on a 1 to 100 scale, determined chiefly by simulation at stated indoor humidity levels. A number quoted without its basis cannot be verified. (9.1)
9.2 The condensation rating basis shall be as indicated in the datasheet.

Minimum Condensation Ratingrange
rating
203040455055606570758090100
Per drawings — energy compliance documentation (deferred by default)
NOTE Interior surface condensation forms where the interior surface temperature of the frame or the glass edge falls below the interior dew point, so the rating required at a given location follows from the interior design humidity and the winter design temperature rather than from the product alone. Where interior humidity is elevated by process or occupancy, as in a natatorium, an ice rink, or a food processing area, the governing dew point is well above that of a conventionally conditioned space. (9.4)
9.5 The Contractor shall submit the framing manufacturer's written confirmation that the proposed assembly meets the indicated condensation rating at the project's interior design temperature and relative humidity.

10 Acoustic Performance

NOTE Sound transmission class and outdoor-indoor transmission class rate the same assembly against different spectra. Outdoor-indoor transmission class weights low-frequency content more heavily, so an assembly selected on sound transmission class alone can perform poorly against traffic, rail, and aircraft noise. (10.1)
10.2 Where an acoustic rating is required, laboratory sound transmission loss shall be measured in accordance with ASTM E90.
10.3 The minimum sound transmission class, rated in accordance with ASTM E413, shall be as indicated in the datasheet.

202225273032354045
Per drawings — acoustic requirements on the contract documents (deferred by default)
10.5 Where the Contract Documents establish no acoustic rating for a storefront area, no acoustic performance is required in that area.
NOTE Acoustic performance of a glazed aluminum assembly is governed chiefly by the glazing rather than the framing. Dissimilar lite thicknesses break the coincidence dip that matched lites share, a viscoelastic interlayer damps the panel, and a wider cavity lowers the mass-air-mass resonance. Ratings above the range that standard storefront framing accommodates generally require a cavity deeper than the framing pocket, which changes the framing depth selection. (10.6)

11 Windborne Debris Impact Resistance

NOTE Where the project is located in a windborne debris region, glazed openings are required by the building code either to resist missile impact and subsequent cyclic pressure loading or to be protected by an impact-resistant covering. (11.1)
11.2 Where impact resistance is required, the assembly shall be tested in accordance with ASTM E1886 and shall satisfy the criteria of ASTM E1996 for the missile level and wind zone indicated in the datasheet.
11.3 The required missile level shall be as indicated in the datasheet.

Per drawings — structural drawings (deferred by default)
NOTE An impact rating belongs to a tested assembly, not to a component. The glass make-up, interlayer, glazing method, framing profile, bite, and anchorage are all variables in the qualifying test, so a rating earned by one combination does not transfer to another. (11.5)
11.6 Impact-rated assemblies shall be furnished exactly as configured in the qualifying test report, including glass make-up, interlayer type and thickness, glazing method, glazing bite, framing profile, and anchor type and spacing.
11.7 The Contractor shall not substitute any component of an impact-rated assembly without a revised test report or a written engineering evaluation from the framing manufacturer accepted by the Engineer of Record.

12 Inter-Story Drift Accommodation

NOTE A storefront supported at two levels of a moving structure is displaced in its own plane when the structure racks. The framing accommodates that displacement through anchor slots, joint clearance, and glass edge clearance; when those are exhausted the load transfers into the glass edge and the perimeter seal. (12.1)
12.2 The framing and anchorage shall accommodate the design inter-story drift indicated in the datasheet, in either in-plane direction, without glass breakage, permanent framing deformation, or loss of the perimeter seal.

12.3 Where the datasheet requires drift testing, drift accommodation shall be verified in accordance with AAMA 501.4 on a specimen representing the project's framing, glazing, and anchorage.
12.4 The structural calculations shall state the anchor slot length, joint width, and glass edge clearance relied on to accommodate the design drift, and the shop drawings shall dimension each of them.

13 Aluminum Extrusions

13.1 Extruded aluminum for framing members, door stiles and rails, glass stops, pressure plates, and trim shall conform to ASTM B221.
13.2 Aluminum sheet and plate for closures, anchor plates, and formed flashings furnished under this standard shall conform to ASTM B209.
13.3 The alloy and temper of structural framing members, door stiles, and door rails shall be as indicated in the datasheet.

NOTE Temper governs the strength available from a given profile, and the higher tempers are what allow a slender mullion to carry hardware reaction and wind load. The lower temper is more readily formed and is adequate where a member carries only its own weight and the gasket reaction. (13.5)
13.6 The minimum wall thickness of structural framing members and door stiles and rails shall be as indicated in the datasheet.

13.8 Steel reinforcement furnished inside an aluminum framing cavity shall be hot-dip galvanized, or shall be isolated from the aluminum by a non-conductive separator, so that the dissimilar metals are not in direct contact in the presence of moisture.

14 Thermal Barrier

NOTE A thermal barrier interrupts the continuous aluminum path between the exterior and interior faces of a framing member. The interruption is what allows the interior surface to stay near room temperature, and it also means the two aluminum halves are joined only through the barrier, so the barrier carries shear between them. (14.1)
14.2 The thermal barrier method shall be as indicated in the datasheet.
Thermal Barrier Methodselect
Not thermally broken
Poured and debridged polyurethane
Pultruded glass-reinforced polyamide strut, mechanically crimped

14.3 Where a thermal barrier is indicated, its nominal width measured across the interruption shall be as indicated in the datasheet.
Thermal Barrier Nominal Widthrange
mm
61014162024283236405060
NOTE A wider interruption lowers the assembly U-factor and raises the interior surface temperature, and it also deepens the profile and increases cost. Where the barrier is a rigid strut rather than a poured polymer, more shear is transferred between the two aluminum halves, so the composite member is stiffer for the same profile depth, and the two halves can be finished separately before assembly, which is what makes a different interior and exterior color possible. (14.4)
14.5 Composite thermal barrier framing shall have been evaluated in accordance with AAMA TIR-A8 for the shear transfer relied on in the structural calculations.
14.6 The thermal barrier shall be continuous through every framing member of the thermally broken portion of the assembly, and shall not be bridged by an anchor, fastener, reinforcement, or accessory that creates a continuous metal path between the exterior and interior faces.
14.7 Where a fastener must cross the thermal barrier, the Contractor shall submit the framing manufacturer's detail showing the isolation provided, and the thermal performance report shall reflect that detail.

15 Framing System Configuration

15.1 Framing Depth and Sightline

NOTE Framing depth sets the section modulus available to carry wind load and the pocket depth available for the glazing, and it governs the wall thickness the head, jamb, and sill details must resolve. Sightline is the exposed face dimension seen in elevation and is an independent selection. (15.1.1)
15.1.2 The nominal framing system depth shall be as indicated in the datasheet.

15.1.4 The framing depth shall be reconciled with the wall thickness, the head and sill flashing details, and the entrance door leaf thickness before the shop drawings are submitted.

15.2 Glazing Pocket Position

NOTE The position of the glazing pocket within the framing depth determines where the glass plane sits relative to the framing faces, which changes the elevation shading, the head and sill flashing geometry, and the depth of the interior and exterior reveals. (15.2.1)
15.2.2 The glazing pocket position within the framing depth shall be as indicated in the datasheet.
Glazing Pocket Positionradio

15.3 Framing Joinery

NOTE The method used to join a horizontal to a vertical determines how the joint is sealed against water and how much of the vertical member's section is removed to make the connection. (15.3.1)
15.3.2 The framing joinery method shall be as indicated in the datasheet.
Framing Joinery Methodselect
Screw spline
Shear block
Stick set with sealed butt joints
Captured pressure plate over a mullion body
15.3.3 Every framing joint shall be sealed with the sealant and in the sequence published by the framing manufacturer for the joinery method used, and the joint sealant shall be compatible with the glazing gaskets and the perimeter sealant.
15.3.4 Field-cut ends of framing members shall be deburred and sealed before assembly.

15.4 Mullion Spans and Reinforcement

15.4.1 Mullion spacing shall be as indicated on the storefront elevations.
15.4.2 The unsupported span of every vertical mullion shall be verified against the framing manufacturer's published span tables for the design wind pressure, the tributary width, and the reinforcement condition furnished.
NOTE A slender aluminum mullion reaches its deflection limit before it reaches its stress limit, so long spans are governed by stiffness. Reinforcement raises stiffness without changing the exposed profile, and an intermediate support removes the span problem entirely at the cost of a structural attachment the building must provide. (15.4.3)
15.4.4 The vertical mullion reinforcement method shall be as indicated in the datasheet.
Vertical Mullion Reinforcement Methodselect
No reinforcement
Steel tube inserted in the mullion cavity
Aluminum stiffener inserted in the mullion cavity

15.4.5 Maximum lite dimensions shall be verified against ASTM E1300 for the design wind pressure and the glass make-up furnished, and the insulating glass unit submittal shall state the largest lite on the project.

16 Glass

16.1 Glass Lite Construction

NOTE Annealed, heat-strengthened, fully tempered, and laminated glass differ in strength, in fracture behavior, and in the fabrication that must precede heat treatment. Heat treatment relieves nothing after the fact, so every hole, notch, and edge finish is completed before the lite is heat treated. (16.1.1)
16.1.2 Flat glass shall conform to ASTM C1036.
16.1.3 Heat-strengthened and fully tempered glass shall conform to ASTM C1048.
16.1.4 Laminated glass shall conform to ASTM C1172.
16.1.5 Coated glass shall conform to ASTM C1376, and the coating type and the surface on which it is applied shall be stated in the insulating glass unit submittal.

Heat Soak Testing of Tempered Glassradio
○ Required for all fully tempered lites
○ Not required
NOTE Nickel sulfide inclusions present in the glass batch can expand years after tempering and fracture a tempered lite with no external cause. Heat soak testing holds the tempered lite at elevated temperature long enough to break the affected lites in the factory rather than in the wall. (16.1.13)

16.2 Safety Glazing

16.2.1 Glazing in a hazardous location defined by the building code shall be safety glazing conforming to 16 CFR 1201 or ANSI Z97.1 at the category required by the code for the location.
16.2.2 Glazing in an entrance door leaf, in a sidelight adjacent to a door, and in any other hazardous location identified by IBC Section 2406 shall be fully tempered or laminated.
16.2.3 Heat-strengthened glass does not satisfy a safety glazing requirement, and shall not be furnished in a hazardous location.
16.2.4 Every safety glazing lite shall carry a permanent manufacturer marking identifying the fabricator and the safety glazing standard and category to which it conforms, located so that it remains visible after installation.

16.3 Laminated Glass Interlayer

NOTE Interlayer chemistry sets the post-breakage stiffness, the shear transfer between plies, the acoustic damping, and the ultraviolet and edge moisture tolerance of the laminate. A stiffer interlayer lets a laminate be counted on structurally after the glass has cracked; a softer or specifically damped interlayer buys sound attenuation instead. (16.3.1)
16.3.2 The laminated glass interlayer type shall be as indicated in the datasheet.

16.3.4 Laminated glass edges concealed within the glazing pocket shall be sealed against moisture in accordance with the laminator's published instructions where the interlayer is moisture sensitive.

16.4 Low-Emissivity Coatings

NOTE Glass surfaces are numbered from the exterior, so surface 1 is the outdoor face of the outboard lite and the highest number is the indoor face of the innermost lite. A low-emissivity coating placed on a cavity-facing surface of the outboard lite rejects solar gain before it enters the cavity; the same coating on a cavity-facing surface of the inboard lite reflects interior heat back inward and admits more solar gain. Placement is therefore a climate and orientation decision, not a quality decision. (16.4.1)

17.1.3 The insulating glass unit cavity fill shall be as indicated in the datasheet.
Insulating Glass Unit Cavity Fillradio
○ Air
○ Argon
○ Krypton
NOTE Cavity conductance falls as the cavity widens until convection begins within the cavity, after which further widening gives nothing back. A denser, less conductive fill gas both lowers conduction and shifts the onset of convection, which is why a krypton unit reaches its lowest conductance at a narrower cavity than an argon unit does. (17.1.4)
17.1.5 Insulating glass units shall be factory fabricated and delivered as sealed units.
17.1.6 Insulating glass units shall not be fabricated, cut, or modified at the project site.
17.1.7 The insulating glass unit fabricator shall be certified under a program that verifies conformance to ASTM E2190, and the certification shall be current at the time of fabrication.

17.2 Edge Seal and Spacer

NOTE The edge seal is the life-limiting component of an insulating glass unit. The primary seal is the vapor barrier and the secondary seal is the structural bond that holds the lites together and protects the primary seal; when the secondary seal is loaded in a way it was not designed for, the primary seal fails and the cavity fogs. (17.2.1)
17.2.2 The insulating glass unit spacer type shall be as indicated in the datasheet.
Insulating Glass Unit Spacer Typeselect
Roll-formed aluminum box spacer
Roll-formed stainless steel spacer

Insulating Glass Unit Edge Sealselect
Polyisobutylene primary with polysulfide secondary
Polyisobutylene primary with polyurethane secondary
Polyisobutylene primary with silicone secondary
Single-seal silicone
Single-seal thermoplastic
NOTE Spacer conductance sets the glass edge temperature, and the glass edge is the coldest interior surface of a glazed assembly in winter, so the spacer governs where condensation appears first and it moves the assembly condensation rating more than the cavity does. (17.2.4)
17.2.5 Where structural silicone glazing is indicated, the insulating glass unit secondary seal shall be silicone and shall be compatible with the structural silicone sealant, and the unit fabricator shall confirm that compatibility in writing.
17.2.6 Where a unit is set at an elevation substantially different from its point of fabrication, the unit fabricator shall state in the submittal whether a capillary or breather tube is furnished and how it is sealed after installation.

18 Glazing

18.1 Glazing Method

NOTE A dry glazed pocket seals against compressed gaskets on both faces of the lite and is assembled without cure time. A wet seal replaces or supplements a gasket with a field-applied sealant and depends on surface preparation and cure conditions. Structural silicone transfers wind load from the glass to the frame through the sealant itself, which makes the sealant a structural element with its own design, testing, and quality control requirements under AAMA CW-13 and AAMA SSGDG-1. (18.1.1)
18.1.2 The glazing method shall be as indicated in the datasheet.
Glazing Methodselect
Dry glazed with gaskets at both faces
Wet glazed at the exterior face with a gasket at the interior face

Two-sided structural silicone with captured opposing edges
Four-sided structural silicone
18.1.3 Where structural silicone glazing is indicated, the structural silicone bite and glueline thickness shall be determined by calculation for the design wind pressure and the lite dimensions, and the calculation shall be included in the structural submittal.
18.1.4 Where structural silicone glazing is indicated, the Contractor shall submit the silicone manufacturer's adhesion and compatibility test results for every substrate the sealant contacts, and shall perform daily field adhesion testing during application in accordance with the sealant manufacturer's published procedure.
18.1.5 Where structural silicone is field applied, the Contractor shall record ambient temperature, relative humidity, substrate preparation, lot numbers, and the operator for each work period, and shall include those records in the closeout submittals.

18.2 Glazing Gaskets

18.2.1 The glazing gasket material shall be as indicated in the datasheet.
Glazing Gasket Materialselect
Ethylene propylene diene monomer
Silicone
Thermoplastic elastomer

18.2.2 Dense elastomeric gaskets shall conform to ASTM C864 and cellular elastomeric gaskets shall conform to ASTM C509.
18.2.3 Gasket durometer and profile shall be as published by the framing manufacturer for the glazing pocket and the glass thickness furnished, so that the gasket is compressed within its working range at the design glass thickness.
18.2.4 Gaskets in contact with a silicone sealant or with a silicone insulating glass unit secondary seal shall be silicone or shall be confirmed compatible in writing by the sealant manufacturer.
NOTE An incompatible gasket can plasticize an adjacent sealant or stain the glass edge seal, and the failure appears months after glazing, when the affected units are already installed and finished around. (18.2.5)

18.3 Setting Blocks and Glass Clearances

18.3.1 The setting block material shall be as indicated in the datasheet.

18.3.4 Setting blocks shall be located at the quarter points of the sill edge unless the framing manufacturer's published glazing instructions establish different locations for the lite size and aspect ratio furnished, in which case those locations shall govern.
NOTE A setting block placed under only one lite of an insulating glass unit loads the edge seal in shear and is a direct cause of premature seal failure. (18.3.5)
18.3.6 Edge clearance, face clearance, and glazing bite shall comply with the GANA Glazing Manual and the framing manufacturer's published glazing instructions, and the shop drawing section details shall dimension each of them.

18.4 Glazing Pocket Drainage

NOTE A captured aluminum glazing pocket is designed to admit and drain incidental water rather than to exclude it absolutely, so its performance depends entirely on the drainage path staying open. (18.4.1)
18.4.2 The exterior glazing pocket shall be drained to the exterior through weeps in the exterior glass stop or in the sill member.
18.4.3 Weep size, location, and spacing shall be as published by the framing manufacturer for the system furnished.
18.4.4 Weeps shall discharge onto an exterior surface that sheds the water clear of the wall below, and shall not discharge into a sealant joint, a concealed cavity, or a flashing pocket that has no outlet.
18.4.5 Internal framing drainage cavities shall be interconnected to a weeped outlet at every horizontal member and at the sill.
18.4.6 Weeps shall be left open and unobstructed, and the Contractor shall verify that every weep is open before the work is accepted.
NOTE Blocked weeps convert a drained pocket into a reservoir and are the most frequently identified cause of water reaching the interior through an otherwise correctly built storefront. (18.4.7)

19 Perimeter Sealant Joints

NOTE The perimeter joint between the storefront frame and the adjoining construction accommodates thermal movement of the aluminum relative to a substrate with a different coefficient of expansion, construction tolerance, and structural movement, all at once. Joint width follows from the total calculated movement and the movement capability of the sealant, so narrowing the joint to improve appearance moves the sealant outside its rated range. (19.1)
19.2 The perimeter sealant chemistry shall be as indicated in the datasheet.
Perimeter Sealant Chemistryselect

19.4 Sealant joints exposed to pedestrian traffic or to abrasion at a threshold or a sill shall be Grade P or shall be protected by a cover, and shall not be Grade NS.
19.5 The backer rod type shall be as indicated in the datasheet.
Backer Rod Typeselect
Closed-cell polyethylene
Open-cell polyurethane
Bi-cellular with a closed skin
NOTE An open-cell rod lets a moisture-cure sealant cure from both faces; a closed-cell rod punctured during installation outgasses into the uncured sealant and blisters the joint. The rod type therefore follows from the sealant chemistry rather than being an independent selection. (19.6)
19.7 Backer rod type shall be confirmed compatible with the selected sealant by the sealant manufacturer, and the Contractor shall not substitute a rod type without that written confirmation.
19.8 Joint width and depth shall comply with the sealant manufacturer's published joint design, sized for the calculated total movement between the storefront frame and the adjoining construction.
19.9 The sealant manufacturer shall confirm in writing the compatibility and adhesion of the selected sealant to the framing finish and to each adjoining substrate, based on samples of the actual materials to be used.
19.10 Where an adhesion test fails, the Contractor shall apply the primer or surface preparation directed by the sealant manufacturer and shall repeat the test at the Contractor's cost until it passes.

20 Entrance Doors

20.1 Door Leaf Proportions

NOTE Stile width sets the section available to resist the reaction of a closer arm and the anchorage of a lock or exit device, and it is also the most visible proportion of the door in elevation. The trade names narrow, medium, and wide stile refer to conventional dimension bands rather than to fixed values, and manufacturers differ on where the bands fall. (20.1.1)

20.1.5 The entrance door mid-rail arrangement shall be as indicated in the datasheet.
Entrance Door Mid-Railradio
○ No mid-rail
○ Mid-rail at lock height

NOTE A mid-rail provides the continuous section that a mortise exit device or a mortise lock case is housed in, so a leaf without one constrains the hardware that can be mounted on it. (20.1.6)
20.1.7 The entrance door leaf thickness shall be compatible with the framing pocket depth so that the leaf operates within its frame without binding and within the perimeter clearance the weatherseal is designed to close.

20.2 Door Leaf Construction

Entrance Door Corner Constructionselect
Mechanical mortise and tenon with sealed joints
Screw spline with sealed joints
Welded and dressed corners

NOTE The corner joint is where the leaf's racking resistance is developed and where water entering the glazing pocket collects, so it is both the structural and the water-management critical detail of the leaf. (20.2.2)
20.2.3 Every corner joint shall be sealed against water entry into the internal leaf cavity.
20.2.4 The internal cavity of the door leaf shall be drained to the exterior at the bottom rail.
20.2.5 Hardware anchorage in a door leaf shall bear on a reinforcement, a backing plate, or a tie rod within the stile or rail, and shall not rely on the extrusion wall alone.
NOTE Cyclical hardware loads work fasteners loose out of a thin extrusion wall over the life of a high-traffic entrance, and the resulting play is what eventually distorts the leaf. (20.2.6)

20.3 Door Glazing

20.3.1 Door leaf glazing shall be as indicated in the glazing schedule, and where the schedule does not identify a separate door glass type it shall match the adjacent storefront glazing.
20.3.2 Door leaf glazing and sidelight glazing shall satisfy the safety glazing requirements of this standard for hazardous locations.
20.3.3 Door leaf glazing stops shall be secured from the interior face of the leaf, or shall be secured with tamper-resistant fasteners where they occur on the exterior face.

20.4 Door Clearances and Accessibility

20.4.1 Doors on an accessible route shall comply with ICC A117.1 for clear opening width, maneuvering clearance, opening force, hardware operability, hardware mounting height, and threshold height.

NOTE ICC A117.1 limits the opening force of an interior door on an accessible route to 5 lbf, and that limit applies to the force required to operate the hardware and overcome the closer, not to the force required to overcome a pressure differential across the opening. The building code sets separate, higher limits for exterior and other doors. (20.4.5)
20.4.6 Where the measured opening force at an exterior door exceeds the indicated limit because of wind, stack effect, or building pressurization, the Contractor shall report the condition to the Engineer of Record rather than reduce the closer spring power below the size required to reliably latch the leaf.

21 Entrance Door Hardware

21.1 Hardware Sets and Coordination

21.1.1 Hardware shall be grouped into hardware sets, and each opening shall be assigned a hardware set as indicated on the door schedule.
21.1.2 Every opening assigned the same hardware set shall receive identical hardware.
21.1.3 The hardware schedule shall be prepared or reviewed by a certified architectural hardware consultant.
21.1.4 The hardware schedule shall confirm for each opening that every scheduled item is compatible with the door stile and rail dimensions, is listed by its manufacturer for use on an aluminum stile and rail door, and satisfies the egress and accessibility requirements of the adopted code for that opening.
21.1.5 A device listed only for hollow metal or wood doors shall not be furnished on an aluminum entrance door without the device manufacturer's written confirmation of the application.
21.1.6 Where the parties disagree whether a scheduled item is suitable for an opening, the Engineer of Record shall make the initial determination.

21.2 Hanging Devices

NOTE An entrance leaf carries its weight through the hanging device across a service life measured in millions of cycles, so the hanging method sets both the sag behavior of the leaf and the floor and header construction the opening requires. A continuous device distributes the load along the full leaf height; a pivot concentrates it at two points and puts the closer, where a floor closer is used, into the floor construction. (21.2.1)

21.2.5 The hanging device shall be sized by its manufacturer for the leaf weight, leaf width, and cycle rate of the opening, and the sizing basis shall be stated in the hardware submittal.

21.3 Door Closers

Door Closer Functions Requiredcheckbox
☑ Adjustable closing speed
☑ Adjustable latch speed
☑ Back-check
☐ Adjustable back-check position
☐ Delayed action
☐ Hold-open
☐ Adjustable spring power
NOTE Back-check resists the leaf beyond a set opening angle, which is what stops a wind-caught leaf from driving its hardware into the adjacent glazing or wall. It restrains the leaf; it does not stop it, so it does not replace a stop or holder. (21.3.4)
21.3.5 Each closer shall be adjusted at substantial completion so that the leaf latches reliably from the fully open position under the building's normal operating pressure differential, and so that the measured opening force complies with the limit indicated in the datasheet.
21.3.6 Where the two adjustments conflict at a given opening, the Contractor shall report the conflict to the Engineer of Record rather than resolve it unilaterally.

21.4 Exit Devices

21.4.1 Exit devices shall conform to ANSI/BHMA A156.3.
21.4.2 Where the adopted building code requires panic hardware or fire exit hardware for the occupancy and occupant load served by an opening, an exit device satisfying that requirement shall be furnished at that opening.

NOTE Vertical rod devices latch a leaf at its head and sill, which is what allows a pair of leaves to be secured without a fixed mullion; a rim device latches into a strike and therefore needs something fixed to latch into. The concealed variants place the rods within the leaf, which requires the leaf section to accommodate them. (21.4.4)

Surface mounted adjustable sweep with an elastomeric insert
Surface mounted automatic drop seal
Concealed automatic drop seal mortised into the bottom rail
NOTE A drop seal is raised clear of the floor while the leaf swings and is driven down against the threshold as the leaf closes, so it can seal against a tighter clearance than a sweep that must ride over the floor through the whole swing. It also introduces a cam mechanism that requires adjustment and eventual replacement. (21.7.4)
21.7.5 The door perimeter weatherseal shall be as indicated in the datasheet.
Door Perimeter Weathersealselect
Pile weatherstrip set in a kerf
Fin seal set in a kerf
Compression bulb seal

21.7.6 Perimeter weatherseals shall be continuous at the head, at both jambs, and at the meeting stiles of a pair, with no gap at a corner or a transition.
21.7.7 Weatherseals and door bottom seals shall be replaceable from the accessible face without removing the leaf, the frame, or the threshold.

22 Aluminum Finishes

22.1 Finish Selection

NOTE An anodic coating is an integral conversion of the aluminum surface and its color comes from the oxide itself or from pigment deposited within it; an organic coating is applied over the metal and its color comes from the coating. The two families weather differently, are repaired differently, and differ in the color ranges available. (22.1.1)
22.1.2 The finish on exterior-exposed aluminum shall be as indicated in the datasheet.
Exterior Exposed Aluminum Finishselect
Mill finish
Architectural Class I clear anodic coating
Architectural Class I integral color anodic coating
Architectural Class I electrolytically deposited color anodic coating
Architectural Class II clear anodic coating
Architectural Class II integral color anodic coating
Anodic coating with a clear organic topcoat per AAMA 612
Organic coating per AAMA 2603
Organic coating per AAMA 2604

NOTE A different interior and exterior finish requires that the two halves of a framing member be finished before they are joined, which is available where the thermal barrier is assembled from separately finished profiles and is not available where the barrier is poured into a single extrusion. (22.1.4)
22.1.5 The finish color shall be as indicated in the datasheet.
Finish Colortext
Enter value...
Per drawings — finish schedule (deferred by default)
22.1.6 The Contractor shall confirm with the coating applicator that the specified color, gloss, and any metallic or mica effect are available in the selected finish system before the finish is released, and shall report any unavailable combination to the Engineer of Record.

22.2 Anodic Coatings

22.2.1 Anodic coatings shall conform to AAMA 611 at the architectural class indicated in the datasheet.
22.2.2 Minimum anodic coating thickness and coating weight shall be as established by AAMA 611 for the indicated class:
Architectural class Minimum coating thickness Minimum coating weight
Class I 0.7 mil 32 mg/in²
Class II 0.4 mil 17 mg/in²
NOTE Anodic coating thickness governs how long the oxide layer resists the abrasion, weathering, and cleaning that will be applied to it, so the class is selected against the exposure and the expected maintenance rather than against appearance, which is indistinguishable between classes when new. (22.2.3)
NOTE Anodic color is developed in the oxide and varies with alloy chemistry, extrusion lot, bath condition, and rack position, so two runs of the same specified color will not match exactly. Anodized aluminum also cannot be touched up in the field the way an organic coating can. (22.2.4)
22.2.5 All anodized extrusions for a single storefront elevation shall be anodized from the same alloy lot and in a single production run, or shall be run in a controlled sequence with documented color matching between runs.
22.2.6 The Contractor shall submit range samples establishing the acceptable color limits before production anodizing begins, and finished work outside the accepted range shall be replaced at the Contractor's cost.

22.3 Organic Coatings

NOTE AAMA 2603, AAMA 2604, and AAMA 2605 establish progressively more demanding requirements for the same measured properties, principally color retention, gloss retention, chalk resistance, and film integrity after a stated period of South Florida exposure. The three are distinguished by the severity and duration of the exposure the coating must survive, not by the coating being a different kind of product. (22.3.1)
22.3.2 Organic coatings shall conform to the AAMA specification indicated in the datasheet, and the coating applicator shall furnish test data demonstrating conformance for the specific color furnished.
22.3.3 Organic coatings shall be applied to a pretreated surface in accordance with the coating manufacturer's published process, and the pretreatment shall be identified in the submittal.
22.3.4 Dry film thickness shall be as required by the applicable AAMA specification and shall be verified and recorded by the applicator for each production run.
22.3.5 Field touch-up of an organic coating shall be limited to abrasion and minor damage, shall use the coating manufacturer's air-dry touch-up product for the furnished color, and shall not be used to repair a member with damage to the substrate or to the pretreatment.
NOTE An air-dry touch-up is a different chemistry from the factory-cured coating and weathers differently, so an extensive touch-up will become visible as the surfaces age at different rates. (22.3.6)

23 Anchorage and Perimeter Conditions

23.1 Anchorage Methods

23.1.1 The storefront shall be anchored to the surrounding structure at the head, sill, and jambs by anchors sized and located by the project structural calculations.

23.1.6 Fasteners and anchors in contact with aluminum shall be stainless steel, or shall be a coated carbon steel isolated from the aluminum, so that the connection is not a galvanic cell.
23.1.7 Anchors shall not be installed into light-gauge steel framing, wood framing, or a substrate that has not been engineered to receive the calculated anchor reactions.
23.1.8 Where the surrounding construction cannot receive the anchor reactions, the Contractor shall report the condition to the Engineer of Record before installation, and reinforcement of the surrounding construction shall be provided before the storefront is set.

23.2 Movement Accommodation

NOTE The structure above a storefront deflects under live load and creep after the storefront is set, and the framing must absorb that movement without transferring the load above into the head member. (23.2.1)
23.2.2 The vertical movement allowance at the head anchorage shall be as indicated in the datasheet.
Head Anchorage Vertical Movement Allowancerange
in.
0.250.3750.50.7511.52
Per drawings — structural drawings (deferred by default)
23.2.3 The head condition shall be detailed so that the indicated vertical movement is accommodated without loading the framing, without closing the perimeter joint below its minimum sealant width, and without loss of the air and water seal.
23.2.4 Anchor slots and clearances relied on for movement shall not be filled with sealant, grout, shim stock, or fastener heads that prevent the movement they were provided for.

23.3 Sill Water Management

NOTE A sill component that collects and drains incidental water is what keeps water that gets past the exterior seal from reaching the construction below. It only works if the water it collects has somewhere to go and cannot run off the end of the run. (23.3.1)
23.3.2 The sill water management method shall be as indicated in the datasheet.
Sill Water Management Methodselect
Continuous extruded aluminum subsill receptor
Sheet metal sill pan flashing
Flexible membrane sill pan flashing

No end dam
23.3.4 Unless the datasheet indicates otherwise, an end dam shall be provided at every termination of a subsill or sill pan, including at each jamb and at each intermediate break in the run.
23.3.5 The sill component shall be drained to the exterior, and its drainage outlet shall discharge onto an exterior surface rather than into a concealed cavity.
23.3.6 Sill pan flashing, head flashing, end dams, and perimeter counterflashing shall be coordinated with Sheet Metal Flashing And TrimSheet Metal Flashing and TrimResolves to the current adopted revision.sync/sheet-metal-flashing-and-trim.
23.3.7 Sill and head flashings shall be installed and sealed before the storefront framing is set into the rough opening.
NOTE Water collected by a sill component that runs out an open end enters the wall construction directly below the sill, where it is concealed from view until the damage is substantial. (23.3.8)

23.4 Air and Water Control Layer Continuity

23.4.1 The air control layer and the water resistive barrier of the adjoining wall shall be sealed continuously to the perimeter of the storefront framing, with no break in either layer across the opening.
23.4.2 The perimeter air and water control transition shall be as indicated in the datasheet.

Per drawings — perimeter transition details
23.4.3 The transition material shall be confirmed compatible with the adjoining barrier, with the framing finish, and with the perimeter sealant by the transition material manufacturer.
23.4.4 Transition materials shall be lapped in shingle fashion from the bottom up so that water reaching the transition from above is directed onto the exterior face of the storefront or into the sill component, and never behind the barrier.
23.4.5 The Contractor shall obtain the Engineer of Record's observation of a completed perimeter transition at the first opening of each condition type before the transition is concealed by adjoining construction.

24 Delivery, Storage, and Handling

24.1 Framing members shall be delivered with the finish protected by a strippable film, a paper interleaf, or an equivalent protection, and the protection shall remain in place until the member is installed.
24.2 Materials shall be stored above grade, under cover, on skids or in racks, and shall be protected from standing water, from mortar and concrete splatter, and from ultraviolet degradation of gaskets and sealants.
24.3 Insulating glass units shall be stored upright on resilient blocking with air circulation between units, and shall not be stacked flat.
NOTE Glass stored in contact with standing water, or in a stack where water can be drawn between lites, stains at the glass surface, and the stain cannot be removed. (24.4)
24.5 Sealants, gaskets, and thermal barrier components shall be stored within the temperature range published by their manufacturers, and material stored outside that range or past its shelf life shall be removed from the site.
24.6 Damaged, deformed, or finish-marred members shall be replaced and shall not be repaired in the field except as permitted by the finish requirements of this standard.

25 Installation

25.1 Pre-Installation Coordination

25.1.1 Before storefront framing is delivered to the site, the Contractor shall conduct a pre-installation meeting attended by the storefront installer, the glazier, the trades installing the adjoining air barrier, flashing, and cladding, and the structural engineer's representative where anchorage is engineered.
25.1.2 The pre-installation meeting shall establish rough opening dimensions and tolerances, the sequence of perimeter barrier work relative to storefront installation, anchor type and embedment at each condition, glazing and hardware delivery timing, and the field test schedule.
25.1.3 Deficiencies in the adjoining construction identified at the meeting or at delivery shall be corrected before the storefront is installed.

25.2 Rough Opening Tolerances

25.2.1 Rough openings shall be plumb, level, and square within the framing manufacturer's published tolerances, and within the tolerance indicated in the datasheet, whichever is more stringent.
Rough Opening Tolerancerange
in. per 12 ft
0.06250.1250.18750.250.3750.5
25.2.2 An out-of-tolerance opening shall be corrected before framing is set.
NOTE Forcing framing to fit an out-of-square opening locks stress into the assembly, which distorts gasket compression, opens the perimeter joint unevenly, and shortens the life of the sealant. (25.2.3)

25.3 Framing Erection

25.3.1 Storefront framing shall be installed in accordance with the framing manufacturer's written instructions and ASTM E2112 where its practices apply to the condition.
25.3.2 The Contractor shall install the sill component and seal it to the substrate, then the jamb members, then the head member, then the intermediate horizontals and verticals, then the perimeter joint, then the glazing, and finally the doors and their hardware.
25.3.3 Framing members shall be installed plumb, level, and square.
25.3.4 Vertical members shall be within 1/16 in. of plumb over the full member height.
25.3.5 Horizontal members shall be within 1/16 in. of level over the full member length.
25.3.6 Misalignment shall be corrected by adjusting the anchorage or by refabricating the member, and shall not be corrected by shimming the member out of plane.
25.3.7 Aluminum in contact with concrete, masonry, mortar, or preservative-treated wood shall be separated from that material by a coating, a gasket, or a membrane.

25.4 Glazing Installation

25.4.1 Glazing shall be installed after the framing is complete, aligned, anchored, and protected from weather.
25.4.2 Glazing pockets shall be clean, dry, and free of debris and construction residue before a unit is set.
25.4.3 Units shall be set on setting blocks with the interior gasket continuous around the perimeter and the exterior stop and gasket fully engaged.
25.4.4 Gaskets shall be installed in continuous lengths, and where a splice is unavoidable it shall be located as directed by the framing manufacturer's published instructions and shall be sealed.
25.4.5 Insulating glass units shall not be cut, drilled, ground, or otherwise modified at the site, and a unit that does not fit its opening shall be replaced by the fabricator.
NOTE Site modification of a sealed unit breaches the edge seal, and the resulting failure is excluded from the unit warranty. (25.4.6)
25.4.7 Glazing sealants shall be applied within the temperature and humidity range published by the sealant manufacturer, and work performed outside that range shall be removed and replaced.

25.5 Door and Hardware Installation

25.5.1 Entrance doors shall be installed after framing and glazing are complete so that the leaves are not exposed to damage during those operations.
25.5.2 Hardware shall be installed and adjusted in accordance with each hardware manufacturer's written instructions.
25.5.3 Each closer shall be adjusted at substantial completion for closing speed, latch speed, back-check, and, where furnished, delayed action.
25.5.4 The Contractor shall measure and record the opening force at each door at substantial completion and shall include the record in the closeout submittals.
25.5.5 The hardware adjustment verification requirement shall be as indicated in the datasheet.
Hardware Adjustment Verificationselect
Installer adjusts and documents each opening
Certified architectural hardware consultant adjusts and documents each opening
Independent third party verifies and documents each opening
Not required

26 Field Testing

NOTE Laboratory testing qualifies the system as designed; field testing verifies the assembly as built, including the perimeter transitions that no laboratory specimen contains. Field water test pressures are set below laboratory pressures by AAMA 502 and AAMA 503 because the field specimen includes those transitions and the chamber seal itself. (26.1)
26.2 The laboratory tests required shall be as indicated in the datasheet.
Laboratory Performance Tests Requiredcheckbox
☑ Air infiltration per ASTM E283
☑ Static water penetration per ASTM E331
☐ Cyclic water penetration per ASTM E547
☑ Structural performance per ASTM E330
☐ Thermal transmittance and condensation resistance per AAMA 1503
☐ Inter-story drift per AAMA 501.4
☐ Missile impact and cyclic pressure per ASTM E1886 and ASTM E1996
☐ Sound transmission loss per ASTM E90
26.3 The field tests required shall be as indicated in the datasheet.
Field Performance Tests Requiredcheckbox
☑ Diagnostic water spray check per AAMA 501.2
☐ Field air leakage per ASTM E783

26.4 The number of field test locations shall be as indicated in the datasheet.
Field Test Locationsrange
locations
1234568101520
Per drawings — field test plan (deferred by default)
26.5 Field test locations shall be selected by the Engineer of Record to represent typical construction, and shall include at least one door perimeter and at least one typical mid-elevation bay where those conditions occur on the project.
NOTE The diagnostic water spray check per AAMA 501.2 applies a calibrated nozzle at no pressure differential and is used to locate leakage at gaskets, joints, and transitions during construction. It does not measure performance and does not satisfy a requirement for chamber testing. (26.6)
26.7 Field testing shall be scheduled after the storefront and the adjoining envelope construction at the test location are complete, and before interior finishes conceal the interior face.
26.8 The field test agency shall be independent of the storefront installer, and shall be engaged and paid by the Owner unless the Contract Documents assign that engagement otherwise.
26.9 Where a field test fails, the Contractor shall repair the deficiency and shall repeat the failed test at the same location at the Contractor's cost until it passes.
26.10 Where a field test fails, the Contractor shall bear the cost of the retest, of the repair, and of removing and reinstating any adjoining work required to make the repair.
26.11 Where two consecutive tests fail at different locations, the Engineer of Record may direct additional test locations, and the Contractor shall bear the cost of those additional tests and of any resulting repairs.
26.12 A repair requiring disassembly of framing shall be documented in writing before it is performed, and shall not void the warranty on framing sections not disassembled.

27 Cleaning and Protection

27.1 Construction Protection

27.1.1 Installed framing, glass, and hardware shall be protected from damage by adjoining construction operations from installation through substantial completion.
27.1.2 Protection shall include guards at door stiles and at exposed mullions where material handling occurs, covering at glass in openings through which construction traffic passes, and removal of abrasive debris before any cleaning operation.
27.1.3 Welding, cutting, and grinding shall not be performed within 25 ft of installed glass unless the glass is shielded by a sacrificial blanket or screen.
NOTE Weld spatter and grinding debris fuse into the glass surface and cannot be removed, so the affected lite is replaced. The cost of that replacement late in a project is far larger than the cost of the shielding. (27.1.4)
27.1.5 Runoff from concrete, masonry, mortar, and fireproofing shall be kept off the storefront finish and glass, and any that reaches those surfaces shall be removed before it dries.

27.2 Final Cleaning

27.2.1 At substantial completion, framing, glass, gaskets, and hardware shall be cleaned in accordance with the framing manufacturer's and the finish manufacturer's published cleaning procedures.
27.2.2 Acidic cleaners, alkaline cleaners, abrasive cleaners, and solvents not identified as acceptable by the finish manufacturer shall not be used on any finished aluminum surface.
NOTE Cleaning agents that damage an anodic or organic finish do so on first contact, and the damage is a permanent change to the finish rather than a soil that can be cleaned off. (27.2.3)
27.2.4 Glass shall be cleaned with a non-abrasive glass cleaner accepted by the glass fabricator.
27.2.5 Razor scraping shall not be performed on a coated glass surface.
27.2.6 The Contractor shall replace glass and finished members that cannot be restored to the accepted appearance standard by the permitted cleaning methods.

28.8 Where a warranted component is repaired or replaced under warranty, the warranty on the repaired or replaced component shall run for a full new term from the date of that repair, or for the remainder of the original term, whichever is longer.
NOTE A re-warranty limited to the remainder of the original term expires almost immediately for a repair performed late in that term, which leaves the Owner with a new component and no coverage on it. (28.9)
28.10 Warranty repair shall include the cost of removing and reinstating adjoining work required for access, and the cost of repairing collateral damage caused by the warranted failure or by the repair.
28.11 Warranty exclusions shall be stated specifically in the warranty document, identifying the excluded cause and its scope.
28.12 A blanket exclusion that does not identify a specific cause shall not be accepted.
28.13 A field test performed under AAMA 502 or AAMA 503, and a repair performed to correct a field test failure, shall not be an excluded cause under any warranty furnished for this work.

29 Spare Parts and Maintenance Materials

29.1 The Contractor shall furnish spare parts and maintenance materials to the Owner at substantial completion, with a written inventory receipted by the Owner.
29.2 The spare parts furnished shall be as indicated in the datasheet.

29.4 Spare gaskets, seals, and setting blocks shall be from the same production lot as the installed material where the material is lot-sensitive, and shall be labeled with the profile designation, the lot, and the date of manufacture.
NOTE Spare material stored beyond the shelf life published by its manufacturer is not usable for its intended repair, so the labeling is what lets the Owner know when the stock must be replaced rather than relied on. (29.5)
