+description: >
+ When to use: Factory-fabricated, relocatable panel-and-frame partition systems
+ for interior commercial, institutional, and industrial fit-outs where walls
+ must be reconfigured without major demolition — solid opaque panels, full- and
+ partial-height glazed panels, and combination assemblies with their framing,
+ floor runners, head tracks, integrated door frames, utility pathways, and
+ accessories. Typical in office tenant improvements, corporate interiors,
+ healthcare clinics, education, and retail fit-outs where repeated
+ reconfiguration or future subletting is the design intent.
+ Not intended for: operable folding/sliding partitions that merge spaces
+ ([[sync/operable-partitions]]); wire mesh security partitions and cage
+ enclosures ([[sync/wire-mesh-partitions]]); conventional gypsum-board
+ stud-framed non-relocatable partitions ([[sync/gypsum-board-assemblies]]);
+ shaft wall and area separation assemblies ([[sync/gypsum-shaft-wall-assemblies]]);
+ raised access flooring even where partition base plates attach to it
+ ([[sync/raised-access-flooring]]); automatic sliding or swinging entrance door
+ units ([[sync/automatic-entrance-doors]]); and all-glass frameless storefront
+ and entrance assemblies ([[sync/all-glass-entrances]]).
+---
+
+# Scope {toc}
+
+## This Standard covers factory-fabricated demountable (relocatable) partition systems and their framing, floor runners, head tracks, integrated door frames, utility pathways, glazing, and accessories. {note}
+
+## The defining attribute of a demountable partition is that it is engineered to be taken down and reassembled — in whole or in part — without the demolition, disposal, and reconstruction that a conventional stud-and-gypsum wall demands. The system arrives as a kit of standardized, interchangeable components on a common track, so a room can be widened, narrowed, or relocated by a trained crew in hours rather than days. The design intent is repeated reconfiguration over the life of the tenancy, not a one-time installation. {note}
+
+## The Contractor shall furnish all panels, framing, tracks, runners, door frames, trim, fasteners, seals, and accessories as a single complete system from one manufacturer's product family.
+
+## Panel construction within the scope of this Standard includes solid opaque panels, full-height single- or double-glazed panels, partial-height glazed panels with a solid lower section, and combination runs that mix opaque and glazed panels on a common floor track. {note}
+
+## A single continuous partition run frequently combines these panel types — for example a glazed conference enclosure with solid panels flanking a doorway. The convention throughout this Standard is that any continuous run sharing one floor track and one head track is one assembly, evaluated as a whole. {note}
+
+## Operable folding and sliding partitions that open to merge two spaces are outside this Standard; specify them under [[sync/operable-partitions]]. {note}
+
+## Wire mesh security partitions and cage enclosures are outside this Standard; specify them under [[sync/wire-mesh-partitions]]. {note}
+
+## Conventional gypsum-board stud-framed partitions that are not engineered for relocation are outside this Standard; specify them under [[sync/gypsum-board-assemblies]], and shaft wall and area separation assemblies under [[sync/gypsum-shaft-wall-assemblies]]. {note}
+
+## Raised access flooring is outside this Standard even where demountable partition base plates bear on or anchor to it; specify the floor under [[sync/raised-access-flooring]] and coordinate the interface per the Installation section. {note}
+
+## Automatic sliding or swinging entrance door units, and all-glass frameless storefront and entrance assemblies, are outside this Standard; specify them under [[sync/automatic-entrance-doors]] and [[sync/all-glass-entrances]] respectively. {note}
+
+## Hinged, sliding, and pivot doors that are factory-assembled modules of the demountable partition product family ARE within this Standard. The boundary is the entrance assembly type, not the leaf: a manual swing leaf carried in the partition frame is in scope; a powered operator or a frameless all-glass entrance is not. {note}

+```
+
+# Quality Assurance {toc}
+
+## Each partition system shall hold a current ICC-ES evaluation report issued under AC522 covering its structural, seismic, and fire/smoke performance. {note}
+
+## AC522 is the primary third-party evaluation pathway for code-compliant demountable partitions, and the major manufacturers carry evaluation reports under it. The evaluation report is the document the building official relies on to accept the system in lieu of prescriptive code provisions. Specifying a rating the listed product cannot satisfy — most commonly a fire-resistance rating — is a recurring error: demountable partitions can serve as smoke-resistant barriers but almost never qualify as fire-resistance-rated assemblies under ASTM E119. {note}
+
+## The manufacturer shall be regularly engaged in the production of demountable partition systems and shall have produced the specified product line for not less than five years.
+
+## The installer shall be trained and certified by the system manufacturer for the specified product line.
+
+## All system components — tracks, runners, panels, doors, connectors, seals, and trim — shall be from a single manufacturer's product family.
+
+## Mixing panels from one source with framing from another is not permitted: the structural evaluation report covers the system as a tested assembly, and substituting a component voids the ESR and the warranty. This single-source rule is also why the door hardware must come from the partition manufacturer rather than the project's hollow-metal door hardware section — the frame prep is proprietary and standard hardware will not fit. {note}
+
+## A mockup of one representative panel run, including one door module and one panel-to-panel and panel-to-glass joint, shall be erected for review and shall become the standard of acceptance.
+
+# Acoustic Performance {toc}
+
+## The partition assembly shall achieve the specified Sound Transmission Class (STC) when tested per ASTM E90 and rated per ASTM E413. {note}
+
+## STC is the single-number rating that owners and designers use to set acoustic privacy expectations. Different panel constructions land in very different ranges: a single-glazed framed panel typically reaches STC 35 to 40, a solid opaque panel STC 40 to 52, and a double-glazed (dual-pane) panel STC 42 to 50. The 80%-case target for a private office or conference room is STC 45. {note}
+
+## The laboratory STC of the selected panel shall be confirmed against the manufacturer's ASTM E90 test report for the exact glass thickness, infill, and frame specified, not an adjacent product.
+
+## Flanking paths through the ceiling plenum and floor shall be addressed in the design and the installation so that field acoustic performance approaches the panel's laboratory rating. {note}
+
+## This is the single most common acoustic failure on demountable partition projects. Specifying STC 45 panels without treating the ceiling plenum and sealing floor penetrations routinely yields real-world performance 8 to 12 points below the laboratory rating, because sound travels over the partition through a continuous plenum and under it through unsealed runner gaps. The partition design must coordinate with the ceiling tile NRC/CAC ratings and any required plenum barriers; see ASTM E557 for flanking-path detailing. {note}
+
+## Select the acoustic performance class:
+```datasheet
+label: Acoustic Performance Class (STC)
+type: radio
+options:
+ - "STC 35 — basic open-plan separation (single-glazed)"
+ - "STC 45 — conference and standard private office (default)"
+ - "STC 52 — executive / private, double-glazed or enhanced solid"
+default: "STC 45 — conference and standard private office (default)"
+```
+
+## Specify the panel cavity treatment for solid panels:
+```datasheet
+label: Solid Panel Acoustic Infill
+type: select
+options:
+ - Mineral wool batt
+ - Fiberglass batt
+ - No infill (visual partition only)
+default: Mineral wool batt
+unit: ""
+```
+
+# Fire and Smoke Performance {toc}
+
+## Exposed panel face materials and infills shall meet ASTM E84 Class A — flame-spread index ≤ 25 and smoke-developed index ≤ 450 — for the occupancies governed by IBC Section 803. {note}
+
+## Class A is the default surface-burning requirement for the corridors and rooms of most commercial occupancies. The test report must be for the actual face material specified, since laminate, fabric, veneer, and glass behave differently. {note}
+
+## Where the partition is designated a smoke-resistant barrier, it shall extend to a smoke-resistant ceiling or bulkhead and be sealed at the head, floor, and all penetrations per NFPA 101 Section 8.4. {note}
+
+## A demountable partition can legitimately serve as a smoke barrier when carried to a rated ceiling or a smoke-resistant bulkhead. It cannot, in nearly all cases, serve as a fire-resistance-rated assembly. The Engineer of Record must confirm which role the partition plays before the rating is specified. {note}
+
+## Specify the fire and smoke designation:
+```datasheet
+label: Fire / Smoke Designation
+type: radio
+options:
+ - Non-rated (typical commercial)
+ - Smoke-resistant barrier to smoke-resistant ceiling or bulkhead
+ - UL-classified fire-resistance-rated assembly (verify a listed product exists)
+default: Non-rated (typical commercial)
+```
+
+# Structural and Seismic {toc}
+
+## The partition and its connections to floor and head track shall be designed for a transverse uniform load of not less than 5 psf for any partition exceeding 6 ft in height, per IBC Section 1607.16. {note}
+
+## This is the minimum lateral load any code-compliant partition over 6 ft must resist; the engineer of record verifies that the runner-to-floor and head-track connections develop it. {note}
+
+## Partitions taller than 6 ft shall be laterally braced to the building structure in accordance with ASCE 7 Section 13.5.7 where required by the Seismic Design Category.
+
+## In Seismic Design Category C and above, the partition shall use the manufacturer's floating head-track detail providing a clearance gap of not less than 1/2 in. (13 mm) on each side at all head-track connections and penetrations. {note}
+
+## The floating head track lets the building structure deflect and sway without loading the partition, and the clearance gap is mandatory in SDC C and above under ASCE 7 Section 13.5.7. Specifying a fixed head track in a seismic project voids the ICC-ES compliance and creates real liability — confirm the detail with the structural engineer of record. {note}
+
+## The floor runner baseplate point and line loads shall be verified against the capacity of the supporting floor finish or raised access floor panel before installation.
+
+## Select the Seismic Design Category governing the project:
+```datasheet
+label: Seismic Design Category
+type: radio
+options:
+ - SDC A or B (no special partition bracing)
+ - SDC C (floating head track + 1/2 in. clearance required)
+ - SDC D, E, or F (floating head track + engineered bracing)
+default: SDC A or B (no special partition bracing)
+```
+
+# Panel Construction {toc}
+
+## Solid Opaque Panels {toc}
+
+### Solid opaque panels shall consist of a rigid core faced on both sides with the specified finish material and edged by the system's framing on all four sides. {note}
+
+### The core may be steel-skinned, aluminum-skinned, or wood-core depending on the product line and the acoustic class; the cavity carries the acoustic infill and any utility raceway. {note}
+
+### The exposed face material shall be the finish selected below and shall carry the ASTM E84 class required for the occupancy.
+
+### Select the solid panel face material:
+```datasheet
+label: Solid Panel Face Material
+type: select
+options:
+ - High-pressure laminate
+ - Fabric-wrapped acoustic
+ - Wood veneer
+ - Markerboard (writable)
+ - Tackboard
+ - Glass whiteboard insert
+default: High-pressure laminate
+```
+
+### Select the frame material and finish:
+```datasheet
+label: Frame Material and Finish
+type: select
+options:
+ - Aluminum extrusion, powder coat
+ - Aluminum extrusion, anodized
+ - Steel, powder coat
+ - Solid wood veneer
+default: Aluminum extrusion, powder coat
+```
+
+### Factory-applied powder coat on frames and metal panel faces shall conform to AAMA 2604 for commercial durability.
+
+### Where a lighter-duty finish is approved, factory-applied powder coat shall conform to AAMA 2603 at minimum.
+
+## Glazed Panels {toc}
+
+### Glazed panels shall be framed lites of the glass type selected below, set in the system's gaskets and retained by the panel framing. {note}
+
+### Single-glazed panels carry one lite in the frame; double-glazed (dual-pane) panels carry two lites separated by an air gap, which is what lifts their STC into the mid-40s. The glazing choice drives both acoustic class and cost. {note}
+
+### Glass shall be tempered or laminated safety glazing meeting IBC Section 2406 where required by location.
+
+### Select the glazing configuration:
+```datasheet
+label: Glazing Configuration
+type: radio
+options:
+ - Single-glazed (one lite, STC ~35-40)
+ - Double-glazed (two lites with air gap, STC ~42-50)
+default: Single-glazed (one lite, STC ~35-40)
+```
+
+### Select the glass type:
+```datasheet
+label: Glass Type
+type: select
+options:
+ - Tempered clear
+ - Tempered fritted or acid-etched
+ - Laminated
+ - Back-painted
+default: Tempered clear
+```
+
+### Select the glass thickness:
+```datasheet
+label: Glass Thickness
+type: radio
+options:
+ - "1/4 in. (6 mm) tempered (single-glaze standard)"
+ - "3/8 in. (10 mm) tempered (higher STC / safety)"
+ - "Laminated (per safety glazing requirement)"
+default: "1/4 in. (6 mm) tempered (single-glaze standard)"
+unit: ""
+```
+
+## Partial-Height and Combination Panels {toc}
+
+### Partial-height panels shall combine a solid lower section with a glazed upper section, with the sill height of the solid base as selected below. {note}
+
+### A common configuration is a 36 in. solid base with glazing above to roughly 9 ft AFF; the acoustic rating of a partial-height run is lower than a full solid run because of the glazed area and any open transom. {note}
+
+### Combination runs mixing opaque and glazed panels shall share a common floor track and head track and shall be coordinated as one assembly.
+
+### Specify the solid base (sill) height for partial-height panels:
+```datasheet

+max: 48
+step: 6
+unit: in
+```
+
+# Panel Dimensions {toc}
+
+## Panel module widths shall be selected from the manufacturer's standard list before the layout is finalized, so that rooms course out without filler panels or corner gaps. {note}
+
+## Standard module widths run 12 in., 18 in., 24 in., 30 in., and 36 in., with 24 in. the common planning module. Laying out rooms to architectural dimensions without first obtaining the manufacturer's module list is a frequent pitfall: it forces filler panels or frame gaps at corners and doorways. Obtain the module list at design development and dimension the rooms to it. {note}
+
+## Panel thickness shall be coordinated with the acoustic class and with the door hardware backset before fabrication. {note}
+
+## The 86 mm (3-3/8 in.) standard cavity is the 80%-case default; a 102 mm (4 in.) enhanced cavity is used for higher acoustic class or thicker glass and deeper utility chases. The thicker cavity changes the door hardware backset, so confirm coordination. {note}
+
+## Select the panel thickness:
+```datasheet
+label: Panel Thickness
+type: radio
+options:
+ - "3-3/8 in. (86 mm) standard cavity (default)"
+ - "4 in. (102 mm) enhanced acoustic / utility cavity"

+label: Partition Height (AFF)
+type: range
+min: 8
+max: 14
+step: 0.5
+unit: ft
+```
+
+## Panels taller than the standard product range shall use the manufacturer's extended-height stud and framing kit, verified against the structural and seismic requirements for the increased height. {note}
+
+## Standard product lines span roughly 8 ft to 10 ft AFF, with 9 ft the 80%-case for commercial spaces. Extended-height kits reach 12 ft to 14 ft for high-bay spaces; confirm the specific product's extended-height ceiling before committing the layout. {note}
+
+# Door Modules {toc}
+
+## Doors integrated into the partition shall be factory-assembled modules of the same product family, with the leaf, frame, hardware prep, threshold, and seals furnished by the partition manufacturer. {note}
+
+## Demountable partition door frames use proprietary hardware prep. Specifying standard hollow-metal hardware in the project's door hardware section produces an RFI when that hardware will not fit the proprietary frame — the door module must be procured complete from the partition manufacturer. {note}
+
+## The door type shall match the selection below and shall be coordinated with the adjacent panel coursing and the accessibility clearances at the opening.
+
+## Door swing, sliding pocket depth, and threshold heights shown on the drawings shall be honored [[drawing: door location and swing]].
+
+## Select the door type:
+```datasheet
+label: Door Type
+type: radio
+options:
+ - Single-leaf hinged (swing)
+ - Sliding pocket door
+ - Sliding bypass door
+ - Frameless pivot door
+default: Single-leaf hinged (swing)
+```
+
+## Select the door leaf material:
+```datasheet
+label: Door Leaf Material
+type: select
+options:
+ - Solid (matching panel face)
+ - Full-glazed tempered
+ - Partial-glazed (vision lite)
+default: Full-glazed tempered
+```
+
+# Utility Integration {toc}
+
+## Electrical and low-voltage raceways within the panel cavity shall be coordinated with the building rough-in so that conduit stubs and junction boxes align with the partition raceway entry locations. {note}
+
+## When the building electrical rough-in does not match the partition raceway entries, the result is field modification after the partition is installed — wires fished in the wrong place, boxes cut where the panel has no chase. The raceway entry locations must be set on the shop drawings and matched by the electrical rough-in. {note}
+
+## Where the partition sits on a raised access floor, the floor runner anchors shall not interrupt the under-floor electrical raceway routing, and the runner load shall be within the raised floor panel rating. {note}
+
+## The floor runner bears on the raised floor panel surface, and the power distribution typically runs in the plenum below. The raised access floor specified under [[sync/raised-access-flooring]] must be coordinated for both the runner point load and a clear path for the under-floor raceways so anchors do not pierce a cable tray or block a feed. {note}
+
+## Full-height partitions cutting across an open-plan HVAC zone shall be flagged for mechanical re-zoning, since an uncoordinated partition creates pressure imbalance and thermal complaints. {note}
+
+## This is a mechanical coordination issue the partition layout should surface early: a new full-height enclosure dropped into an open zone with shared diffusers and returns will starve one side and over-supply the other unless the HVAC is re-zoned or balanced. {note}
+
+## Specify the integrated utility provisions:
+```datasheet
+label: Integrated Utility Provisions
+type: checkbox
+options:
+ - Electrical power raceway in panel cavity
+ - Data / low-voltage raceway
+ - Power outlets and USB charging
+ - Display / monitor mount backing
+ - Coordination with raised access floor power
+```
+
+# Relocatability and Sustainability {toc}
+
+## The system shall be warranted for the specified number of reconfiguration (reuse) cycles, with panels and components rated for reuse after reconfiguration. {note}
+
+## Relocatability is the whole point of a demountable system, so the contract should pin down how many reuse cycles the manufacturer warrants. Leading manufacturers warrant panel components for three to five reconfigurations; where lifecycle performance is a contract requirement, specify the minimum cycle count rather than relying on the catalog default. {note}
+
+## Where LEED Materials and Resources credits or ANSI/BIFMA e3 conformance is a project requirement, the system shall meet the specified minimum recycled content by weight. {note}
+
+## Many demountable systems achieve 30% to 50% recycled content by weight, and some are procured as furnishings under ANSI/BIFMA e3 rather than as a construction specification. The procurement category — construction versus furnishings — is driven by the project delivery method and owner preference and should be settled before bidding. {note}
+
+## Specify the minimum warranted reuse cycles:
+```datasheet
+label: Warranted Reuse Cycles
+type: radio
+options:
+ - 3 reconfigurations (standard)
+ - 5 reconfigurations (enhanced lifecycle)
+default: 3 reconfigurations (standard)

+
+# Installation {toc}
+
+## Installation shall be performed by the manufacturer-certified installer in accordance with the approved shop drawings and the manufacturer's written instructions.
+
+## Floor runners and head tracks shall be set straight, level, and plumb within the manufacturer's tolerance before any panels are set.
+
+## Seismic clearance gaps at the head track shall be maintained at not less than 1/2 in. (13 mm) on each side at all penetrations and connections in Seismic Design Category C and above.
+
+## All floor penetrations, runner gaps, and head-track joints shall be sealed acoustically where the partition carries an STC requirement. {note}
+
+## The acoustic rating specified is meaningless if the perimeter leaks. Sealing the runner-to-floor gap and the head-track joint is what closes the under-partition and over-partition flanking paths that otherwise erode the lab STC in the field. {note}
+
+## The partition-to-ceiling interface shall be coordinated with the ceiling installation, including grid interruption, light fixture relocation, and sprinkler offset where full-height panels meet a suspended ceiling. {note}
+
+## Full-height panels running to the underside of a suspended T-bar ceiling force the ceiling and the partition to coordinate where the grid is cut, where fixtures move, and where sprinkler heads offset. This interface is routinely missed in early design and surfaces as field conflict. {note}
+
+## Select the ceiling interface detail:
+```datasheet
+label: Ceiling Interface
+type: radio
+options:
+ - Full-height to underside of structure (deck)
+ - Stop at suspended ceiling grid with split-stud detail
+ - Floating head track to accommodate slab deflection
+default: Stop at suspended ceiling grid with split-stud detail
+```
+
+# Testing {toc}
+
+## Field acoustic verification shall be performed where the contract specifies a field STC, comparing the installed assembly against the specified rating. {note}
+
+## Where acoustic privacy is contractually critical, a field test confirms that the flanking paths were actually controlled and the installation matches the lab assumptions; it is the only way to catch a plenum or perimeter leak before occupancy. {note}
+
+## Completed partition runs shall be inspected for plumb, level, joint tightness, finish defects, and door operation.
+
+## Any deficiency identified during inspection shall be corrected before acceptance.
+
+# Delivery, Storage, and Handling {toc}
+
+## Panels, glass, and frames shall be delivered in the manufacturer's protective packaging and shall not be unwrapped until ready for installation.
+
+## Glazed panels shall be stored upright on edge in racks, protected from point loads and surface contact that could scratch the glass or finish.
+
+## Materials shall be stored indoors in a dry, conditioned space, protected from moisture, dust, and construction traffic.
+
+# Warranty {toc}
+
+## The manufacturer shall warrant the system against defects in materials and workmanship for not less than the period specified below from the date of Substantial Completion.
+
+## The warranty shall cover the panels and components through the specified number of reconfiguration cycles when relocated by a manufacturer-certified installer.
+
+## Specify the warranty period:
+```datasheet
+label: Warranty Period
+type: radio
+options:
+ - 5 years
+ - 10 years
+ - Manufacturer's standard limited lifetime
+default: 5 years
+```
+
+# Spare Parts {toc}
+
+## The Contractor shall furnish the Owner a stock of spare components to support future reconfiguration without reorder delay.
+
+### The spare-parts stock shall include the following:
+- Connectors, seals, and trim consumed per panel relocation, in the quantity listed in the relocation kit inventory.
+- Not less than two replacement panels of each face material and one spare glazed panel of each glass type.
+- Touch-up finish for each frame and panel face color.
+
