1 Scope

NOTE This standard governs the fabric, hardware, operating systems, mounting, and field procedures for interior window treatments that manage the light and solar heat entering an occupied space through its glazing. (1.1)
NOTE The products in scope are roller shades in solar screen, room-darkening, and blackout fabrics, dual-roller assemblies that carry a solar shade and an opaque shade on one mounting, and draperies hung on architectural track. (1.2)
NOTE A window treatment is selected first for what it does to light. The fabric openness, its solar optical properties, and the way its edges meet the opening decide whether a workstation can be used beside the glass at nine in the morning and whether a room can be darkened for a projected image, and the hardware exists to hold the fabric flat, roll it straight, and put it where the occupant wants it. (1.3)
NOTE Because the fabric hangs freely in an occupied room it is a fire safety element, and because it is operated every day by the people in that room its operating cord is a strangulation hazard governed by ANSI/WCMA A100.1. This standard treats fire performance and cord retention as requirements of the same rank as the optical ones. (1.4)
NOTE Fabric openness varies by orientation on the same building, so it is a per-opening quantity carried on the window treatment schedule, while the fabric family, its fire and emissions performance, the hardware system, and the policy on manual and motorized operation are decided once for the project in the datasheet. (1.5)
NOTE Whether an opening is manual or motorized is a decision independent of which fabric hangs on it; either fabric can be driven either way, and the two selections are made separately in this standard. (1.6)
NOTE The following are governed elsewhere and are outside this standard: (1.7)
  • exterior shading devices, awnings, exterior screens, and sunshades mounted outside the glazing line
  • the glazing, window frames, curtain wall, and storefront the treatments are mounted against
  • horizontal and vertical louver blinds, cellular shades, and roman shades
  • the wall and ceiling blocking and backing the brackets fasten to
  • the lighting control and building automation head-ends and the sequences that command the shades
  • branch circuits and raceways serving shade power supplies
  • valances, cornices, and other soft goods furnished as furniture
1.8 The treatment type and quantity at each opening shall be as indicated on the window treatment schedule.
1.9 Window treatment locations shall be as indicated on the floor plans and interior elevations.

3 Submittals

3.1 Action Submittals

3.1.1 The Contractor shall submit the following for review before any window treatment is fabricated or ordered:
  • a window treatment schedule listing every shade and drapery by opening mark, giving the treatment type, fabric and openness, mounting condition, concealment, operating system, finished width and drop, and quantity, cross-referenced to the floor plans and elevations
  • product data for each fabric, giving the composition, weight, thickness, openness factor, and the published visible transmittance, solar transmittance, solar reflectance, and solar absorptance for the scheduled color
  • product data for the roller tube, brackets, clutch or motor, fascia or pocket components, hembar, channels, and drapery track, with rough-in and clearance dimensions
  • a physical sample of each fabric in each scheduled color, not smaller than 8 in. by 10 in.
  • a finish sample of each exposed hardware finish
  • shop drawings showing each opening condition, the mounting plane and bracket projection, the fascia or pocket detail, the light gap at each jamb, the outside-mount overlap, the channel detail, the division of wide openings into bands, and the alignment of banks to mullions
  • for motorized work, a control riser showing motor type and voltage, power supply locations and their branch circuit feeds, control devices, control zones, the control signal topology, and the interface to any lighting control or building automation system with the demarcation between this work and those systems
  • fire performance reports for each fabric, giving the NFPA 701 test method and result, and the ASTM E84 flame spread and smoke developed indices where an interior finish classification applies
  • low-emitting certification for each fabric where the datasheet requires it
  • fungal resistance and antimicrobial test reports where the datasheet requires them
  • the lightfastness rating of each fabric
Action Submittal Packagecheckbox
☑ Window treatment schedule by opening
☑ Fabric product data with optical properties
☑ Hardware and track product data
☑ Fabric samples in scheduled colors
☐ Hardware finish samples
☑ Shop drawings of opening conditions and details
☐ Motorization control riser and zoning
☑ Fire performance reports

3.1.2 Window treatments shall not be fabricated or ordered until the corresponding action submittals have been reviewed and returned.
NOTE The tube diameter, the fascia depth, and the pocket size each depend on the fabric thickness and the finished drop, so a fabric substitution after the hardware is ordered can leave a roll that no longer fits its fascia. The submittal is reviewed as one coordinated set for that reason. (3.1.3)

3.2 Informational Submittals

3.2.1 The Contractor shall submit the following with or before the action submittals:
  • the manufacturer's written confirmation that each scheduled fabric is qualified on the selected hardware at the largest scheduled width and drop
  • the installer's qualification statement
  • the field measurement record for every opening, taken after the surrounding construction is in place
  • for motorized work, the power supply loading calculation showing the number of motors on each supply against the supply's rated capacity

4 Quality Assurance

4.1 Sources of Supply

4.1.1 The source of the shade fabric relative to the hardware shall be as indicated in the datasheet.
Shade Fabric Sourceradio
○ Fabric from the hardware manufacturer's own fabric line
○ Fabric from a separate fabric source qualified by the hardware manufacturer
4.1.2 The source of the motors and controls relative to the hardware shall be as indicated in the datasheet.
Motor and Control Sourceradio
○ Motors and controls from the hardware manufacturer's own system
○ Motors and controls from a separate control manufacturer qualified by the hardware manufacturer
NOTE A small number of mills weave most of the solar screen fabric sold in the United States, and the same fabric is offered through several hardware manufacturers, so a fabric sourced separately from the hardware is a common arrangement rather than an exception. What the hardware manufacturer supplies in that arrangement is the qualification that the fabric rolls straight on its tube at the scheduled size, which is why the qualification is required rather than the common ownership. (4.1.3)
4.1.4 Whatever the source, the roller tube, brackets, clutch or motor, fascia, and hembar shall be furnished as one coordinated system by a single hardware manufacturer.
4.1.5 Where the fabric is furnished from a separate source, the hardware manufacturer shall confirm in writing that the fabric is qualified on the selected tube at the largest scheduled width and drop.
4.1.6 Where the motors and controls are furnished from a separate source, the hardware manufacturer shall confirm in writing that the motor fits the tube and bracket and that the combination has been tested together.

4.2 Installer Qualification

4.2.1 The installer's authorization status shall be as indicated in the datasheet.
Installer Authorizationradio
○ Installer trained and authorized by the hardware manufacturer
○ Installer experienced with the product type without manufacturer authorization
4.2.2 The installer shall have completed not fewer than the number of projects of comparable size indicated in the datasheet using the selected operating system.
Minimum Comparable Projects Completed by the Installerrange
projects
123510
4.2.3 Where the datasheet leaves the minimum blank, no project count is imposed and the installer's authorization status alone governs.

4.3 Mock-Up

4.3.1 The mock-ups required before the balance of the work is fabricated shall be as indicated in the datasheet.
Mock-Ups Requiredcheckbox
☐ One shade of each type and fabric at a representative opening
☐ One complete bank of shades at a representative facade module
☐ One motorized control zone commissioned and demonstrated
☐ One drapery at a representative opening
NOTE A single-opening mock-up lets the Architect confirm the fabric color and openness against the actual glass and daylight, the light gap, and the fascia alignment before the order is placed. (4.3.2)
NOTE A bank mock-up additionally shows whether adjacent shades read as one element, and a motorized zone mock-up shows whether grouped shades stop at the same height, which is the deficiency most visible from across a room. (4.3.3)
4.3.4 The mock-up shall be installed at the opening the Architect designates, and the balance of the work shall not be fabricated until the Architect has accepted the mock-up in writing.
4.3.5 An accepted mock-up may remain as part of the work.

4.4 Field Measurement

NOTE An inside-mounted shade is cut to the opening it goes into, and a nominal dimension that is wrong by a quarter inch produces either a shade that binds or a light gap twice the width intended. (4.4.1)
4.4.2 The Contractor shall field-measure every opening after the jambs, sills, mullions, ceilings, and pocket framing that bound it are in place, and before any shade or drapery is fabricated.
4.4.3 Each opening shall be measured individually at the head, the mid-height, and the sill, and fabricated to the measured dimension rather than to a nominal one.
4.4.4 The field measurement record shall identify each opening by its mark and shall record the out-of-square and out-of-plumb conditions found.

5 Environmental and Service Conditions

5.1 Solar Exposure by Orientation

NOTE The glare an occupant experiences at a workstation depends on the sun's angle relative to the glass, which changes with orientation and with the hour, so no single fabric openness serves every facade of the same building. (5.1.1)
NOTE An east or west facade takes direct sun at a low angle for part of the day and needs a low openness or a second, opaque shade to hold glare at the work surface. A south facade takes high-angle sun that a moderate openness can manage. A north facade or a borrowed-light interior opening receives diffuse light and keeps its view at a higher openness. (5.1.2)
5.1.3 The openness and optical properties selected for each opening shall be consistent with the orientation and glare exposure of that opening.
5.1.4 Where the window treatment schedule assigns a single fabric to openings of different orientations, the Contractor shall bring the assignment to the Architect's attention before the fabric is ordered, and the Architect shall confirm or revise it in writing.

5.2 Glazing Interaction

NOTE An interior shade works in series with the glass and reduces, but does not eliminate, the solar heat the glass has already admitted. Energy the shade absorbs is re-radiated into the room from the space between the glass and the fabric, so a dark fabric behind clear glass can warm the room while it darkens it. (5.2.1)
NOTE A shade with a high solar reflectance on its exterior-facing side returns part of the admitted energy back through the glass, and the combined performance of glass and shade is evaluated together under NFRC 200 or AERC 1.1 rather than from either component alone. (5.2.2)
5.2.3 The glass visible transmittance and solar heat gain coefficient of each glazed opening shall be obtained from GlazingGlass and GlazingResolves to the current adopted revision.sync/glazing before the fabric optical properties for that opening are finalized.

5.3 Plenum and Interior Finish Locations

NOTE NFPA 701 addresses the flame propagation of a hanging textile and does not by itself classify a material for surface burning, so a fabric that hangs in a location the building code regulates as an interior finish, or a pocket that opens into a return air plenum, carries a second requirement under ASTM E84. (5.3.1)
5.3.2 Where the shade pocket opens into a return air plenum, the pocket materials, the fabric within the plenum, and any insulation or lining shall meet the surface burning classification required for that plenum.

5.4 Humidity Exposure

NOTE Fungal growth on a fabric needs sustained surface moisture, which a conditioned office does not supply and a natatorium, a commercial kitchen, a shower room, or an unconditioned vestibule does, so fungal and antimicrobial performance earns its cost where the space's humidity is sustained rather than where it is conditioned. (5.4.1)
5.4.2 Where a shade hangs in a space in which the relative humidity is sustained above 70 percent by the space's use, the fabric shall carry the fungal resistance selected in the datasheet, and where the datasheet selects none, the Contractor shall report the condition to the Architect before ordering.

6 Window Treatment Types

6.1 The treatment types included in the work shall be as indicated in the datasheet.
Window Treatment Types in the Workcheckbox
☐ Solar screen roller shades
☐ Room-darkening roller shades
☐ Blackout roller shades
☐ Dual-roller shades
☐ Draperies on track
NOTE A solar screen shade is an open-weave fabric selected by openness factor that cuts glare and solar heat while keeping a view through the weave. A room-darkening shade is a dense fabric that reduces light substantially without being opaque. A blackout shade is an opaque fabric that passes no light through its body, and the light that reaches a darkened room comes around its edges. A dual-roller assembly carries two of these on one mounting so the occupant can choose glare control with a view by day and darkness on demand. A drapery is a full-height fabric hung on track where a soft appearance is wanted and stack-back at the jamb is acceptable. (6.2)
6.3 The operating systems included in the work shall be as indicated in the datasheet.
Operating Systems in the Workcheckbox
☑ Manual operation
☐ Motorized operation
6.4 The openings that receive motorized operation shall be as indicated on the window treatment schedule.

7 Solar Screen Fabric

7.1 Fabric Composition

7.1.1 The solar screen fabric composition shall be as indicated in the datasheet.
Solar Screen Fabric Compositionselect
PVC-coated fiberglass yarn
PVC-coated polyester yarn
PVC-free coated polyester yarn
PVC-free coated fiberglass yarn
Uncoated woven polyester
NOTE Fiberglass yarn does not stretch, so a fiberglass-core fabric holds its dimensions on a wide shade and hangs flat in a heated window; polyester yarn is lighter and more tear-resistant but elongates under its own weight on a tall drop, which shows as a wave along the hembar. A PVC coating gives the yarn its dimensional stability and cleanability at the cost of chlorine content, and the PVC-free coatings trade some of that stability for a fabric that can be specified where halogenated materials are excluded. (7.1.2)
7.1.3 The exterior-facing face of the fabric shall be as indicated in the datasheet.
Exterior-Facing Fabric Faceselect
Same color and construction as the room-side face
White or light exterior face on a colored room-side face
Metallized reflective backing
NOTE A light or metallized exterior face raises the solar reflectance of the shade and returns more heat through the glass, while a dark room-side face lowers the fabric's own brightness and sharpens the view through the weave. A two-faced fabric lets both be chosen at once, and it also gives the building a uniform appearance from the street regardless of the interior color. (7.1.4)
7.1.5 Fabric color and pattern for each opening shall be as indicated on the finish schedule.

7.2 Openness Factor

NOTE The openness factor is the percentage of the fabric area that is open weave rather than yarn, and it is the primary lever between glare control and view. (7.2.1)
NOTE A 1 percent openness is nearly closed to glare and rejects the most solar heat but darkens the room and gives the least view; a 10 percent to 14 percent openness gives the clearest view and the most daylight and the weakest glare control; a 3 percent to 5 percent openness sits between the two on most facades. (7.2.2)
NOTE Fabric color interacts with openness. At the same openness a dark fabric holds glare better and gives a sharper view, and a light fabric reflects more heat but produces more diffuse brightness on its own surface. (7.2.3)
7.2.4 The openness factor of the solar screen fabric shall be as indicated in the datasheet.
Solar Screen Fabric Openness Factorrange

Per drawings — the window treatment schedule (deferred by default)
7.2.5 The openness stated on the schedule for an opening shall govern over a project-wide value in the datasheet.
7.2.6 The openness factor shall be the value published by the fabric manufacturer for the selected fabric and color, determined by an optical method rather than by yarn count.

7.3 Solar Optical Properties

NOTE Solar transmittance, solar reflectance, and solar absorptance sum to 100 percent of the solar energy striking the fabric. Solar reflectance on the exterior-facing side is the property that most improves the shade's thermal performance, and visible transmittance is the property most closely tied to glare. (7.3.1)
7.3.2 The minimum solar reflectance of the exterior-facing face shall be as indicated in the datasheet.

7.3.5 Where the datasheet and the schedule state no optical limit for an opening, the fabric's published values for the scheduled color shall be reported in the submittal and no minimum or maximum is imposed.
7.3.6 Optical properties shall be determined by ASTM E903 or ASTM E1175, or under AERC 1.1, and shall be reported for the scheduled color rather than for the fabric line as a whole.
NOTE Values differ by color within one fabric line, and a white and a charcoal of the same weave can differ in solar reflectance by a factor of five. (7.3.7)

8 Room-Darkening and Blackout Fabric

8.1 The construction of room-darkening and blackout fabric shall be as indicated in the datasheet.
Room-Darkening and Blackout Fabric Constructionselect
Acrylic foam-backed woven polyester
Three-layer laminated woven blackout
PVC-coated fiberglass blackout
PVC-free coated blackout
Dense woven polyester room-darkening without opaque backing
NOTE A foam-backed fabric achieves opacity in a thin, soft cloth and rolls to a small diameter, and its backing is the surface that faces the glass. A laminated blackout carries its opaque layer between two decorative faces so both sides can be colored. A coated blackout is the stiffest and most cleanable and is the one that behaves like a solar screen fabric on the roller. (8.2)
8.3 A fabric designated blackout shall have zero openness and a visible transmittance of zero through its body.
8.4 A fabric designated room-darkening shall have a visible transmittance not exceeding the value indicated in the datasheet.
Maximum Visible Transmittance of Room-Darkening Fabricrange
%
0.5123510
8.5 The Contractor shall not represent a dense solar screen or room-darkening fabric as blackout.
NOTE Most of the light that reaches a room behind a blackout shade comes around the fabric edges rather than through the cloth, so an opaque fabric darkens a room only in combination with the perimeter provisions in the Mounting and Light Control section. (8.6)

9 Fabric Fire Performance

9.1 Flame Propagation

9.1.1 Every shade and drapery fabric installed under this standard shall pass NFPA 701 under the test method applicable to its construction and areal density.
9.1.2 The NFPA 701 test method under which each fabric is tested shall be as indicated in the datasheet.
NFPA 701 Test Methodselect
Test Method 1
Test Method 2
Derived — the construction and areal density of the selected fabric, against the applicability limits NFPA 701 sets for each test method (by default)
NOTE NFPA 701 assigns its two test methods by the fabric itself. Test Method 1 applies to single-layer fabrics and multilayer drapery assemblies up to the areal density the standard states, and Test Method 2 applies to heavier fabrics, to vinyl-coated fabrics and blackout linings, and to plastic films, so the method is not a project choice but a consequence of the fabric selected. (9.1.3)
9.1.4 A drapery assembly of face fabric, lining, and interlining shall be tested as the assembly rather than as separate layers.
9.1.5 The fabric supplier's certificate shall identify the fabric by name, the test method, and the test date, and shall be current at the time of submittal.

9.2 Surface Burning

9.2.1 The ASTM E84 surface burning classification required of the fabric shall be as indicated in the datasheet.
Fabric Surface Burning Classificationselect
No surface burning classification required at the installed locations
Class A
Class B
Class C
Derived — the interior finish class the adopted building code assigns to the occupancy and location the shade is installed in, and whether the fabric or its pocket is exposed within a return air plenum (by default)
NOTE A Class A classification is a flame spread index of 25 or less and a smoke developed index of 450 or less under ASTM E84, and a plenum location additionally requires a smoke developed index of 50 or less. (9.2.2)
9.2.3 Where a classification applies, the classification shall be demonstrated for the fabric as installed, including any backing, coating, or lining.

10 Fabric Emissions, Lightfastness, and Hygiene

10.1 Low-Emitting Certification

10.1.1 Whether the fabric is required to carry a low-emitting certification shall be as indicated in the datasheet.
Low-Emitting Fabric Certificationradio
○ Certified low-emitting fabric required
○ Not required
10.1.2 Where a certified low-emitting fabric is required, the fabric shall be certified under UL 2818 to the GREENGUARD Gold criteria or shall be tested under the CDPH Standard Method v1.2 and shall meet its limits.
NOTE Shade fabric is among the largest continuous interior surfaces in an occupied room, so its emissions are weighed by the green building rating systems that count interior products, and a project pursuing such a rating has a concrete reason to require the certification. (10.1.3)

10.2 Lightfastness

NOTE A window treatment fabric is exposed to sunlight every day it is deployed, and the lower portion of a shade that is partly raised for most of the year fades ahead of the portion that stays rolled, so a fabric that fades produces a visibly two-toned shade within a few seasons on a sunny facade. (10.2.1)
10.2.2 The fabric shall hold a gray scale rating of 4 or better under AATCC TM16.3 after the exposure indicated in the datasheet.
Minimum Lightfastness Exposure at Gray Scale Rating 4range
hours
20406080100200300500
10.2.3 Where the datasheet leaves the exposure blank, the fabric manufacturer's published lightfastness rating shall be reported in the submittal and shall become the warranty basis for fading.

10.3 Fungal Resistance and Antimicrobial Activity

10.3.1 The fungal resistance and antimicrobial performance required of the fabric shall be as indicated in the datasheet.
Fungal Resistance and Antimicrobial Performancecheckbox
☐ Fungal resistance demonstrated under ASTM G21
☐ Mildew resistance demonstrated under AATCC TM30
☐ Antimicrobial activity demonstrated under ASTM E2180
NOTE Fungal resistance and antimicrobial activity are different properties. The first is the fabric's own resistance to supporting mold, which a glass or coated polyester yarn has largely by nature; the second is an added agent that inhibits bacteria on the surface, which is a claim a healthcare owner may want documented. (10.3.2)
10.3.3 Where an antimicrobial claim is made for a fabric, the active agent shall be identified in the submittal and its activity demonstrated under ASTM E2180 rather than asserted.

11 Roller Shade Hardware

11.1 Roller Tube

11.1.1 The roller tube material shall be as indicated in the datasheet.
Roller Tube Materialselect
Extruded aluminum
Galvanized steel
11.1.2 The roller tube diameter for each shade shall be as indicated in the datasheet.
Roller Tube Diameterrange
in.
1.251.51.7522.533.54
Derived — the shade width, the rolled fabric volume at the full scheduled drop, and the fabric weight, against the hardware manufacturer's published deflection limit for each tube (by default)
NOTE The tube diameter follows from the width and the load on it rather than from a preference. An undersized tube on a wide shade deflects under its own weight, and a deflected tube makes the fabric wander toward one end as it rolls, which is the defect called telescoping and the most common roller shade complaint. (11.1.3)
11.1.4 Tube deflection at the scheduled width and drop shall not exceed the hardware manufacturer's published limit for straight fabric tracking.
11.1.5 The tube shall carry a continuous fabric attachment along its full length so the fabric is held square to the tube axis.

11.2 Roll Direction

11.2.1 The direction in which the fabric leaves the tube shall be as indicated in the datasheet.
Roll Directionradio
● Regular roll
○ Reverse roll
NOTE A regular roll drops the fabric off the back of the tube nearest the glass, which keeps the fabric closest to the glazing and out of the way of the room. A reverse roll drops the fabric off the front of the tube, which hides the tube behind the fabric where no fascia is used and gains clearance past a window handle or a deep sill projection. (11.2.2)

11.3 Brackets

11.3.1 Each shade shall be carried on a drive-end bracket that houses the clutch or motor and an idler-end bracket, with the brackets sized for the tube diameter and the load.
11.3.2 Banks of adjacent shades shall be carried as indicated in the datasheet.
Bracket Configuration for Banks of Shadesselect
Individual end brackets at each shade
Shared intermediate brackets between adjacent shades
Continuous mounting extrusion carrying the bank
NOTE A shared intermediate bracket carries the idler of one shade and the drive of the next on a single mounting, which keeps the gap between bands small and aligns them at one height. A continuous extrusion goes further and carries the whole bank on one line, which also supports a continuous fascia across the mullions. (11.3.3)
11.3.4 Bracket projection shall clear the glass, the frame, any operable sash, and any window hardware through the full travel of the shade.

11.4 Fabric Width and Banding

11.4.1 Openings wider than the fabric bolt width shall be treated as indicated in the datasheet.
Treatment of Openings Wider Than the Fabric Bolt Widthselect
Railroaded fabric
Seamed fabric
Divided into coupled bands driven by one operator
Divided into independently operated bands
NOTE Railroading turns the fabric so its bolt width runs vertically, which makes a seamless band wider than the bolt at the cost of a pattern turned sideways and a drop limited to the bolt width. A seam keeps the pattern upright and is visible in transmitted light. Dividing the opening into bands keeps every band within the bolt and within the tube's deflection limit, at the cost of a light line between bands. (11.4.2)
11.4.3 The maximum width of a single band shall not exceed the hardware manufacturer's published limit for the selected tube and fabric.
11.4.4 Fabric edges shall be cut cleanly by a method that leaves no loose yarn, and the edges shall be straight and parallel over the full drop.

11.5 Hembar

11.5.1 The hembar type shall be as indicated in the datasheet.
Hembar Typeselect
Concealed hembar sealed in a fabric pocket
Exposed extruded aluminum hembar
Fabric-wrapped exposed hembar
NOTE The hembar weights the bottom of the fabric so it hangs flat and rolls evenly, and its form decides how the bottom edge reads and how it meets a sill. A concealed hembar inside a sewn or welded pocket disappears into the fabric; an exposed hembar reads as a finished bar in a coordinated finish; a wrapped hembar covers the bar in the shade fabric and suppresses the light line at the bottom edge of an opaque shade. (11.5.2)
11.5.3 The hembar shall be straight and shall be weighted for the shade width so that the fabric does not flutter under air movement or hang unevenly.

12 Roll Concealment

12.1 The concealment of the roll at each opening shall be as indicated in the datasheet.
Roll Concealmentselect

NOTE A fascia is a removable extrusion that conceals the roll and the brackets on an exposed mount. A recessed pocket conceals the shade within the ceiling and, with a closure, hides the roll from below at every shade position. A cassette encloses the roll on all sides in a self-contained head. An exposed roll conceals nothing and leaves the tube and fabric roll in view. (12.2)
12.3 Unless the datasheet selects an exposed roll, the roll and its brackets shall be concealed by the selected fascia, pocket, or cassette.
12.4 The fascia profile shall be as indicated in the datasheet.

12.6 The fascia depth shall be not less than the hardware manufacturer's published minimum for the tube and the rolled fabric at the full scheduled drop.
12.7 A recessed pocket shall be sized to the hardware manufacturer's published minimum clear opening for the tube, the rolled fabric at full drop, the brackets, and any closure, and shall provide access to remove the shade without cutting the ceiling.
12.8 Recessed pocket locations and dimensions shall be as indicated on the reflected ceiling plans and ceiling details.

12.10 A fascia across a bank of shades shall be continuous across the bank, or shall be jointed only at mullion lines.

13 Manual Operation

13.1 Manual Operator

13.1.1 The manual operator type shall be as indicated in the datasheet.
Manual Operator Typeselect
Continuous-loop bead chain clutch
Spring-assisted bead chain clutch
Crank operator with a detachable wand
Cordless spring roller
NOTE A bead chain clutch holds the shade at any position and needs no spring adjustment, and it is the operator most of the commercial market runs on. A spring-assisted clutch adds a lift assist for shades whose fabric and hembar weight would otherwise need an unreasonable pull. A crank with a detachable wand removes the loop entirely at the cost of slower operation, and a cordless spring roller is operated at the hembar and suits only openings within reach. (13.1.2)
13.1.3 The bead chain material shall be as indicated in the datasheet.
Bead Chain Materialselect
Stainless steel bead chain
Nickel-plated brass bead chain
Plastic bead chain
NOTE A metal chain carries a heavier shade without stretching and holds its finish, and a plastic chain is quieter against a wall and is not cold to the hand. (13.1.4)
13.1.5 The clutch shall be rated by the hardware manufacturer for the weight of the fabric and hembar at the largest scheduled width and drop, and shall hold the shade at any intermediate position.
13.1.6 The chain loop shall reach the operating height established under the Accessible Operation section and shall not lie on the sill or the floor.

13.2 Cord Retention

NOTE The free loop of a bead chain is a strangulation hazard, and ANSI/WCMA A100.1 addresses it by requiring the loop of a custom corded product to be held under tension by a retention device fastened to the building so that no hazardous loop can form. (13.2.1)
13.2.2 Every continuous-loop chain shall be installed with the manufacturer's cord retention device fastened permanently to the wall, jamb, or sill so that the loop is held taut and cannot be pulled away to form a free loop.
13.2.3 The retention device shall be the device tested with the operator under ANSI/WCMA A100.1, and a field-improvised tie-off shall not be substituted for it.
13.2.4 Where the operator is designed so that the shade does not operate unless the retention device is mounted, that interlock shall not be defeated.
13.2.5 A crank wand, when detached, shall be stored on the hook provided at the opening.

13.3 Corded Operation Policy

13.3.1 Whether corded manual operation is permitted on the project shall be as indicated in the datasheet.
Corded Manual Operationradio
● Permitted
○ Not permitted
13.3.2 Where corded manual operation is permitted, every corded shade shall carry the retention device required under the Cord Retention article.
13.3.3 Where corded manual operation is not permitted, every manual shade shall use a cordless spring roller or a crank operator, or shall be motorized.
NOTE The residual hazard of a corded product is highest in a space occupied by young children, such as a childcare room, a pediatric patient room, or a dormitory, and that is the condition under which a project excludes corded operation rather than relying on the retention device alone. (13.3.4)
13.3.5 The Contractor shall not substitute a corded product at an opening the schedule designates as cordless or motorized.

14 Motorized Operation

14.1 Motor Power Source

14.1.1 The motor power source shall be as indicated in the datasheet.
Motor Power Sourceselect
Low-voltage DC motor from a Class 2 power supply
Line-voltage 120 V AC motor
Line-voltage 277 V AC motor
Battery-powered motor with a rechargeable integral battery
Power over Ethernet motor
NOTE A low-voltage motor is fed from a Class 2 supply through wiring that the shade installer can run without a line-voltage permit, is quiet, and is the motor most control systems are built around; it needs a power supply located within the wiring distance the manufacturer publishes. A line-voltage motor is stronger and suits large shades, and each motor is an electrical outlet requiring a branch circuit and an electrician. A battery motor needs no wiring and needs recharging on an interval set by its use. A Power over Ethernet motor takes power and control on one cable from a network switch, which suits a building already wired for it. (14.1.2)
14.1.3 Low-voltage power supplies shall be listed under UL 1310 as Class 2 power units, or shall be listed Class 2 outputs of a listed control panel.
14.1.4 Power supply locations shall be as indicated on the electrical drawings.
14.1.5 The number of motors connected to one power supply shall not exceed the supply's rated capacity as published, and the loading calculation shall be submitted.
14.1.6 Line-voltage motors shall be fed from branch circuits provided under the electrical work as indicated on the electrical drawings.
14.1.7 Where battery motors are selected, each motor shall be accessible for recharging without removing the shade, and the published cycles per charge shall be stated in the submittal.
14.1.8 Every motorized operator shall be listed under UL 325.
14.1.9 All wiring shall comply with NFPA 70, and radio-frequency devices shall comply with 47 CFR Part 15.
14.1.10 The responsibility for low-voltage shade power and control wiring shall be as indicated in the datasheet.

14.2 Motor Sound Level

14.2.1 The maximum sound level of a motor in operation shall be as indicated in the datasheet.
Maximum Motor Sound Level at 3 ftrange
dBA
30353840424446485055
14.2.2 Where the datasheet leaves the sound level blank, the motor manufacturer's published sound level shall be reported in the submittal and no limit is imposed.
NOTE A motor that is inaudible in a lobby is audible in a conference room while a presentation is under way, and the quiet motors sold for that setting cost more and run slower, so the limit is set by the space rather than by the product. (14.2.3)

14.3 Motor Limits

14.3.1 Upper and lower travel limits shall be set for every motorized shade at commissioning so that the hembar stops at the head and at the sill positions the Architect designates.
14.3.2 Limit settings shall be recorded by shade mark and delivered with the closeout submittals.
14.3.3 Where the motor provides intermediate preset positions, the presets for each control zone shall be programmed as directed by the Architect and recorded.

14.4 Control Signal Topology

14.4.1 The control signal topology shall be as indicated in the datasheet.
Control Signal Topologyselect
Wired low-voltage control bus
Radio-frequency wireless
Ethernet network
Dry-contact or analog inputs from another control system
NOTE A wired bus is immune to the interference and the range limits of radio, and every device on it is a wiring drop. Radio control needs no control wiring and is the simpler retrofit, and its range is reduced by the metal studs, the ductwork, and the concrete the building is made of, so a repeater plan is part of the design. A networked motor addresses each shade on the building network and depends on that network being available. Dry-contact control makes the shade a slave to another system and offers no feedback. (14.4.2)
14.4.3 Where radio control is selected, the Contractor shall verify signal reception at every motor and control device before the ceilings are closed, and shall provide repeaters where reception is not reliable.

14.5 Control Integrations

14.5.1 The control devices and integrations provided shall be as indicated in the datasheet.
Control Devices and Integrationscheckbox

14.5.3 Where an interface to the lighting control or building automation system is selected, this work shall provide the motors, the shade-side controllers, the gateway, and a documented point list, and the sequences that command the shades shall be the work of Lighting ControlsLighting ControlsResolves to the current adopted revision.sync/lighting-controls or Building Automation SystemBuilding Automation SystemResolves to the current adopted revision.sync/building-automation-system.
NOTE An automated solar-tracking sequence positions each zone by the sun's computed angle on that facade, and a daylight sequence positions it by a measured light level. The first needs no sensor and never reacts to a cloud; the second reacts to conditions and needs a sensor whose view of the sky is kept clear. (14.5.4)
14.5.5 Wall-mounted control stations shall be located as indicated on the electrical drawings.

14.6 Control Zones

14.6.1 Motorized shades shall be grouped into control zones as indicated on the contract documents.
14.6.2 Shades within one zone shall respond to a single command and shall stop at the same height within the tolerance stated under Testing.
NOTE A zone is the unit an occupant commands, and a bank of shades that shares one solar condition and one room is commanded as one zone so that the facade reads as one element and no occupant is left with a single shade out of step with the rest. (14.6.3)

15 Dual-Roller Shades

15.1 The fabric pairing on dual-roller assemblies shall be as indicated in the datasheet.
Dual-Roller Fabric Pairingselect
Solar screen shade with blackout shade
Solar screen shade with room-darkening shade

15.2 The bracket arrangement of dual-roller assemblies shall be as indicated in the datasheet.
Dual-Roller Bracket Arrangementradio
○ Single dual bracket carrying both tubes
○ Two independent brackets stacked front and back
NOTE A dual bracket carries both tubes on one mounting at a fixed spacing and a single fascia depth, and is the arrangement the hardware manufacturers publish pocket and fascia dimensions for. Two stacked brackets let the two shades be mounted at different planes, which an offset head condition can require, at the cost of a deeper pocket and two sets of anchorage. (15.3)
15.4 Each shade of a dual-roller assembly shall be operated independently of the other.
15.5 Where one shade of a dual-roller assembly is motorized, both shall be motorized unless the schedule indicates otherwise for that opening.
15.6 The pocket, fascia, and bracket projection at a dual-roller assembly shall be sized for both rolls at full drop.

16 Draperies and Track

16.1 Track and Operation

16.1.1 Drapery track shall be extruded aluminum architectural track with carriers, end stops, and master carriers rated by the track manufacturer for the weight of the scheduled drapery at the scheduled fullness.
16.1.2 The drapery track operation shall be as indicated in the datasheet.

Drapery Draw Configurationselect
Center opening
One-way draw
Per drawings — the window treatment schedule (deferred by default)
16.1.5 Stack-back position and dimension for each drapery shall be as indicated on the window treatment schedule.
NOTE A drapery that stacks over the glass reduces the daylight opening by the stack width, and a drapery that stacks past the jamb needs wall beyond the opening to stack onto, so the stack-back is decided at each opening with the elevation in view. (16.1.6)

16.2 Heading, Fullness, and Lining

16.2.1 The drapery heading style shall be as indicated in the datasheet.
Drapery Heading Styleselect
Ripplefold
Pinch pleat

16.2.2 The fullness ratio of the drapery fabric width to the track width shall be as indicated in the datasheet.
Drapery Fullness Ratiorange
ratio
11.21.51.822.53
NOTE Fullness is the fabric folded into the finished width, and it decides both the appearance and the stack. A ripplefold heading runs at a fullness set by its snap tape and carrier spacing, while a pleated heading is sewn to whatever fullness the fabric allows, so the ratio and the heading are chosen together. (16.2.3)
16.2.4 The drapery lining shall be as indicated in the datasheet.
Drapery Liningselect
Unlined
Lined
Blackout lined
Lined and interlined
NOTE A lining protects the face fabric from sun and gives the building a uniform appearance from outside; a blackout lining makes the drapery opaque; an interlining adds a soft layer that improves the drape and the thermal and acoustic value of the assembly at the cost of weight the track has to carry. (16.2.5)
16.2.6 Drapery fabric for each opening shall be as indicated on the finish schedule.
16.2.7 Every layer of the drapery assembly shall meet the flame propagation requirement of this standard, tested as the assembly.

17 Mounting and Light Control

17.1 Mounting Condition

17.1.1 The mounting condition at each opening shall be as indicated in the datasheet.
Mounting Conditionselect
Inside jamb mount
Outside mount on the wall face
Outside mount on the mullion face
Ceiling or soffit mount
Per drawings — the window treatment schedule (deferred by default)
NOTE An inside mount sets the shade within the reveal for the cleanest relationship to the window and leaves a light gap at each jamb equal to the bracket deduction. An outside mount oversizes the shade past the opening to overlap the wall or mullion and closes that gap, at the cost of a larger visible shade and a projection into the room. A ceiling or soffit mount hangs the shade from above and is the mount a recessed pocket uses. (17.1.2)
17.1.3 The mounting condition shall be coordinated with the jamb, mullion, and head construction of the opening, and the Contractor shall report an opening whose construction cannot receive the scheduled mount to the Architect before fabrication.

17.2 Light Gap at Inside Mounts

17.2.1 The maximum light gap at each jamb of an inside-mounted shade shall be as indicated in the datasheet.
Maximum Light Gap per Side at Inside Mountsrange
in.
0.250.3750.50.6250.751
17.2.2 Where the datasheet leaves the gap blank, the hardware manufacturer's published bracket deduction for the selected operator shall govern.
NOTE The gap between the fabric edge and the jamb is set by the width the bracket and clutch or motor occupy, and it cannot be reduced below that deduction without the fabric rubbing the jamb. The deduction differs between a clutch and a motor, so a mixed manual and motorized bank shows two gap widths unless the hardware is selected to equalize them. (17.2.3)
17.2.4 The light gap shall be measured from the fabric edge to the jamb face at the mid-height of the opening, and the gap at the two jambs of one shade shall not differ by more than 1/8 in.

17.3 Outside Mount Overlap

17.3.1 The overlap of an outside-mounted shade past each side of the opening shall be as indicated in the datasheet.
Outside Mount Overlap per Siderange
in.
0.511.52346
Per drawings — the window treatment details
NOTE A larger overlap closes the side light path more completely and covers an out-of-square opening, and it also widens the shade past what the eye reads as the window. (17.3.2)

17.4 Perimeter Light-Control Channels

17.4.1 The perimeter channels provided at room-darkening and blackout shades shall be as indicated in the datasheet.
Perimeter Light-Control Channelsselect
No perimeter channels
Side channels at both jambs
Side channels at both jambs and a sill channel
Per drawings — the window treatment schedule
NOTE A side channel captures the fabric edge and blocks the light path at the jamb, and a sill channel captures the hembar and closes the bottom. Together with a closed head they make the darkening the opaque fabric promises, and without them a blackout shade leaves a bright frame of light around itself. A solar screen shade gains nothing from channels, because light passes through its weave regardless. (17.4.2)
17.4.3 Where channels are selected, the fabric edges shall run within the channels over the full travel without binding, and the channels shall be light-tight to the jamb and sill.
17.4.4 Where channels are selected, the head shall be closed by a fascia, cassette, or pocket closure that blocks light between the roll and the head.
17.4.5 The Contractor shall not represent a blackout shade installed without perimeter channels as achieving full darkening.
17.4.6 Channel details and the resulting overlap onto the wall shall be as indicated on the window treatment details.

17.5 Banks and Mullion Alignment

17.5.1 Where shades occur in a bank across a glazed facade, the shades, brackets, fascia, and hembars shall align with the window mullions and with each other so that the bank reads as one element.
17.5.2 Adjacent bands in a bank shall align in height at every stopped position, and the gap between bands shall be consistent across the bank within 1/8 in.
17.5.3 Mullion locations shall be as indicated on the window elevations.

18 Accessible Operation

18.1 The provision for operation at openings on an accessible route shall be as indicated in the datasheet.
Accessible Operation Provisionselect
Manual operator within the reach range and operable with one hand
Motorized operation with a wall control within the reach range
18.2 Where the adopted accessibility code requires the operable parts at an opening to be accessible, the chain, wand, or control shall be located within the reach range ICC A117.1 and the 2010 ADA Standards establish for the approach at that opening, and shall be operable with one hand without tight grasping, pinching, or twisting of the wrist.
NOTE A bead chain loop meets the reach requirement only where its retention device places the loop within the reach range, and a crank wand meets it only while the wand is stored where it can be reached. Motorized operation with a wall control at switch height meets it directly, and is the reason motorization is selected at openings whose head is beyond reach. (18.3)
18.4 The openings designated accessible shall be as indicated on the accessibility plans.

19 Testing

19.1 The field demonstrations performed before acceptance shall be as indicated in the datasheet.
Field Demonstrations Requiredcheckbox
☑ Full-travel operation of every manual shade
☑ Straight fabric tracking without telescoping
☑ Cord retention device installed and fastened at every corded shade
☑ Upper and lower limits set at every motorized shade
☑ Level deployment of every control zone
☐ Control device and integration response by zone
☐ Perimeter light seal at every channeled opening
☐ Full travel of every drapery on its track
19.2 The Contractor shall operate every manual shade through its full travel in the presence of the Architect and demonstrate that the clutch holds at intermediate positions and that the fabric tracks without rubbing the jamb.
19.3 Fabric shall not drift laterally on the tube by more than 1/8 in. over one full lowering and raising, and where the parties disagree whether a shade is telescoping the Architect shall make the initial determination.
19.4 The Contractor shall demonstrate at every corded shade that the retention device is fastened to the building and holds the loop taut.
19.5 The Contractor shall operate every motorized shade from each control device that commands it and demonstrate correct direction, the commissioned upper and lower limits, and operation within the sound level selected.
19.6 Shades within one control zone shall stop within 1/4 in. of the same height at every commanded position.
19.7 Where an interface to the lighting control or building automation system is provided, the Contractor shall demonstrate each zone's response to a command from that system with a representative of that system present.
19.8 Where perimeter channels are provided, the Contractor shall demonstrate the darkening achieved at a representative channeled opening with the room lights off.
19.9 A shade that fails a demonstration shall be corrected and demonstrated again, and the cost of the correction and of the repeated demonstration shall be borne by the Contractor.

20 Installation

20.1 Anchorage and Blocking

NOTE The operating load, the weight of a wide shade, and the handling the shade receives in service pull a fastener set in gypsum board alone out of the wall, and blocking behind the board cannot be added after the wall or ceiling is closed without opening it. (20.1.1)
20.1.2 Brackets, mounting extrusions, fascia, pockets, channels, retention devices, and drapery track shall be fastened to blocking, backing, framing, or structure.
20.1.3 Blocking and backing for window treatments shall be installed during framing under Rough CarpentryRough CarpentryResolves to the current adopted revision.sync/rough-carpentry and Gypsum Board AssembliesGypsum Board AssembliesResolves to the current adopted revision.sync/gypsum-board-assemblies at the locations shown on the shop drawings.
20.1.4 The Contractor shall confirm the blocking locations against the shop drawings before the wall and ceiling substrates are closed, and shall report a missing or misplaced block to the Architect before closure.
20.1.5 Anchorage at openings where no backing exists shall be as indicated in the datasheet.
Anchorage Where No Backing Existsradio
○ Hollow-wall anchors permitted with the Architect's acceptance
○ Hollow-wall anchors not permitted
20.1.6 Where hollow-wall anchors are not permitted, backing shall be added and the substrate closed before the bracket is installed.
20.1.7 Where hollow-wall anchors are permitted, each anchor shall be rated by its manufacturer in the substrate present for not less than four times the operating load at that bracket, and the anchor type shall be identified on the shop drawings for the Architect's acceptance.
NOTE An existing wall in a renovation, and a wall on which the blocking was not placed, present the same problem, and the two answers differ in cost and in the certainty of the result. A rated anchor set correctly in a substrate it was rated for carries a light shade for the life of the building; the same anchor in a substrate it was not rated for does not, and the failure is not visible until the shade comes down. (20.1.8)

20.2 Sequence and Protection

20.2.1 Window treatments shall be installed after the ceilings, the wall finishes, the glazing, and the principal dust-generating work in the space are complete.
20.2.2 Where the schedule requires shades to be installed before that work is complete, they shall be kept in their protective packaging or covered in place until the work is complete.
20.2.3 Shades and draperies shall be installed level and plumb, at the mounting condition scheduled, in accordance with the hardware manufacturer's published instructions.
20.2.4 Fabric shall be handled with clean hands or gloves, and a fabric that has been soiled, creased, or kinked during installation shall be replaced rather than cleaned in place.
NOTE Soils and oils are difficult to remove from a shade fabric, and an abrasive or solvent cleaning the fabric manufacturer has not approved damages the weave, the coating, or the color. (20.2.5)

20.3 Cleaning

20.3.1 At completion the Contractor shall clean every fabric by the fabric manufacturer's approved method and shall remove packaging, labels, and debris from the work.
20.3.2 A cleaning method the fabric manufacturer has not approved shall not be used on any fabric under this standard.

21 Delivery, Storage, and Handling

21.1 Shades, draperies, and hardware shall be delivered in the manufacturer's protective packaging with each item labeled by its opening mark.
21.2 Shades shall be delivered to the site not earlier than the point in the construction sequence at which the spaces receiving them are ready to receive and protect them.
21.3 Shades and fabric rolls shall be stored indoors in a clean, dry, conditioned space, flat or upright as the manufacturer directs, off the floor, and away from moisture, direct sunlight, and construction traffic.
21.4 Fabric shall not be stored where it can be crushed, kinked, or soiled, and a roll that has been stood on its end or has had material stacked on it shall be inspected for creasing before installation.
21.5 Motors, power supplies, and control devices shall be stored within the temperature and humidity limits published for them.
21.6 Items damaged in transit, in storage, or in handling shall be replaced rather than repaired unless the Architect accepts a specific repair in writing.

22.6 Where the contract documents state a longer warranty period than the datasheet, the longer period shall govern.
22.7 A warranty correction shall include removal and reinstallation of the affected shade, replacement of fabric that cannot be matched within the same dye lot across a bank, and repair of finishes damaged in gaining access, at no cost to the Owner.
22.8 Work performed under this warranty shall itself be warranted for a full new term equal to the original period measured from the date the correction is completed, or for the remainder of the original period, whichever ends later.
22.9 The warranty shall exclude damage from abuse, from a cleaning method the fabric manufacturer has not approved, and from operation outside the manufacturer's instructions.

23 Spare Parts

Fabric Attic Stock as a Percentage of Installed Arearange
%

NOTE Attic stock of a fabric is cut from the same dye lot as the installed shades, and a shade replaced later from a new lot can differ visibly from its neighbors in a bank, which is what the attic stock exists to prevent. (23.2)
23.3 The Contractor shall deliver the spare hardware and control items indicated in the datasheet to the Owner before the work is accepted, and shall obtain a signed receipt for them.
Spare Hardware and Control Itemscheckbox
