1 Scope
1.1This standard covers the furnishing and installation of factory-fabricated visual display units, including markerboards, tackboards, combination units, map and display rails, sliding and folding panel systems, bulletin board cabinets, and the framing, trim, trays, and accessories furnished with them.
NOTE Visual display units are the writing and pinning surfaces of a building — the markerboards and tackboards that turn classrooms, conference rooms, nursing stations, and offices into places where information is composed and posted. (1.2)
NOTE They are nominally simple millwork-adjacent items, but the wrong surface choice has a long, visible, daily-use consequence: a melamine board that ghosts within a semester, a glass board hung on a wall with no blocking, or a modular rail that fails an accessibility review. This standard exists to make those choices deliberately rather than by default. (1.3)
NOTE The unit of selection in this standard is the assembled display unit — a writing or pinning surface, its core, and the frame, trim, and accessories furnished as a factory package — not the raw sheet of porcelain steel or cork. (1.4)
NOTE Surface coatings applied liquid in the field — whiteboard paint and chalkboard paint rolled or sprayed directly onto a wall or door — are a finish-trade item and are not covered here even though the resulting surface performs the same function. (1.5)
NOTE Digital and electronic display boards, interactive flat panels, and roll-down or fixed projection screens are audiovisual systems and are outside this standard; only the passive mounting track ("projection screen receiver") furnished as part of a visual display wall is coordinated here. (1.6)
NOTE Several adjacent products that visually resemble a visual display unit are specified in their own standards rather than here: (1.7)
- Architectural interior signage, wayfinding, and code-required egress signage are specified in Signage, even where a directory or notice board visually resembles a bulletin cabinet.
- Wall and corner protection panels furnished for impact and abuse resistance, rather than as a writing or display surface, are specified in Wall And Corner Protection.
- Acoustic wall panels furnished primarily for sound absorption are specified in Acoustic Wall Panels; a fabric-faced tackboard furnished primarily as a pinning surface is covered here even if it provides incidental absorption.
- Toilet accessories (Toilet Accessories), metal lockers (Metal Lockers), window treatments (Window Treatments), and wood or laminate casework with a whiteboard insert (Wood And Laminate Casework).

3 Submittals
NOTE Action submittals establish that the proposed units meet the specified performance and finish before the manufacturer cuts material, while informational and closeout submittals carry the fire-test evidence, warranty, and maintenance instructions the Owner needs to live with the units for decades. (3.1)
3.2The Contractor shall submit the following action submittals for review and approval before fabrication:
- Product data for each type of visual display unit, including surface material, core construction, frame profile, and accessories.
- Shop drawings showing elevations, dimensions, joint and trim locations, accessory placement, and required blocking and backing.
- Samples of each writing surface, tackboard face, and frame finish in the specified colors.
- Fabric tackboard face samples in the full available range when fabric color is selected by the Architect.
☐ Product data for each unit type
☐ Shop drawings with elevations and blocking
☐ Writing surface / tackboard face samples
☐ Frame finish samples
☐ Fabric face range (when Architect-selected)
3.3The Contractor shall submit the following informational submittals:
- Manufacturer's certification that surface and core materials meet the specified ASTM E84 surface-burning class.
- Manufacturer's certification that aluminum trim is finished to the specified AAMA 611 anodic class or factory paint system.
- Installation instructions, including required blocking, fastener types, and mounting heights.
☐ ASTM E84 class certification

- Executed written warranties, including the porcelain-enamel surface warranty where applicable.
- Operation and maintenance data, including cleaning agents permitted and prohibited for each surface.
☐ Executed written warranties
☐ Operation and maintenance / cleaning data
4 Quality Assurance
NOTE Visual display units shall be the standard factory products of a single manufacturer regularly engaged in their production, furnished as complete assemblies rather than site-assembled from loose components. (4.1)
4.2Units of a given type throughout the Project shall be the products of a single manufacturer.
4.3The installer shall be experienced in mounting factory-fabricated visual display units and shall follow the manufacturer's published instructions for the substrate encountered.
NOTE A mockup is the cheapest place to discover that an anodized frame reads gray against a warm-white wall, or that a fabric tackboard photographs differently than its swatch; on finish-sensitive projects one installed unit of each type should be reviewed before the balance is fabricated. (4.4)
4.5Where a mockup is required, one full unit of each specified type shall be installed in its final location and reviewed before the remaining units are fabricated, and the approved mockup may remain as part of the Work.
5 Regulatory and Accessibility Requirements
NOTE A wall-mounted board is an interior finish and a potential protruding object at the same time; it must satisfy the fire performance of IBC Section 803 and the reach and protrusion limits of the ADA Standards, and these two demands occasionally pull against each other. (5.1)
5.2Surface and core materials of markerboards and tackboards shall meet the surface-burning class required for the occupancy and sprinkler condition under IBC Section 803, tested per ASTM E84.
NOTE A Class A interior finish requires a Flame-Spread Index of 25 or less and a Smoke-Developed Index of 50 or less; some occupancies and sprinklered spaces permit Class B (Flame-Spread Index 75 or less, Smoke-Developed Index 450 or less), but Class A is the safe institutional default and the assumption of this standard unless a lower class is documented. (5.3)
● Class A (FSI ≤25, SDI ≤50)
○ Class B (FSI ≤75, SDI ≤450)
5.4Wall-mounted units and their operable parts shall comply with the ADA Standards for Accessible Design and, where adopted by the authority having jurisdiction, ICC A117.1.
5.5A unit mounted with any point of its leading face between 27 inches and 80 inches above the finished floor shall not protrude more than 4 inches from the wall plane into the circulation path.
NOTE Modular rail systems and stacked sliding panels are the usual offenders against the 4-inch protrusion limit, because the panel thickness plus the rail can exceed 4 inches even when each part seems thin; verify the assembled projection, not the catalog panel thickness. (5.6)
5.7Operable parts furnished with the unit — map hooks, sliding-panel pulls, and cabinet latches — shall be within an accessible reach range, with the highest operable part no higher than 48 inches above the finished floor for a forward or unobstructed side reach.
5.8The bottom of a unit intended for accessible writing or posting should be mounted so the writing surface begins within the side-reach range, with the bottom edge no lower than 15 inches above the finished floor where a floor-level reach obstruction governs.
Per drawings — interior elevations (deferred by default)
6 Markerboards
NOTE A markerboard is defined by its writing surface, and the surface choice is the single most consequential decision in this standard because it governs daily usability, magnet support, and warranty life — a 50-year porcelain surface and a 2-year melamine surface look nearly identical on day one and nothing alike after a year of classroom use. (6.1)
NOTE The four common writing surfaces sit on a clear durability-versus-cost ladder: (6.2)
- Porcelain enamel on steel — fired glass-on-steel surface; the most durable and stain-resistant, inherently magnetic, and the correct choice for daily-use institutional rooms; typically carries a 50-year surface warranty.
- Tempered glass — low-iron glass writing surface; premium, ghost-free, and easy to clean; magnetic only when a steel backing is specified; typically a 10-year warranty.
- Painted steel — mid-grade coated-steel surface; better than melamine for moderate use; magnetic but less stain-resistant than porcelain.
- Melamine — resin-faced economy surface; light-duty only, not reliably magnetic, and prone to ghosting and staining under frequent use.
6.3The writing surface material shall be as selected for the room's use frequency, with porcelain enamel on steel specified for classrooms, training rooms, and other rooms used multiple times daily.
NOTE Specifying a melamine surface in a room used several times a day is the most common and most regretted error in this section; melamine ghosts and stains within months of institutional use, and the cost difference to porcelain is recovered many times over in service life. (6.4)
● Porcelain enamel on steel
○ Tempered low-iron glass
○ Painted steel
○ Melamine
6.5Where the design intent shows magnets holding paper to the board, the specified surface shall be inherently magnetic — porcelain enamel on steel, or glass over a steel backing — and melamine shall not be substituted.
NOTE Magnet support is not an aesthetic preference but a substrate fact: only a ferrous backing holds a magnet, so a melamine or bare-glass board will silently fail the design intent the first time a teacher reaches for a magnet. (6.6)
○ Yes — ferrous substrate required
● No
6.7The markerboard core shall be a rigid laminated assembly that holds the writing surface flat over its full span and resists denting from normal handling.
NOTE Honeycomb aluminum cores are the standard institutional choice because they are light and stay flat; particleboard cores appear in economy lines and add weight and warp risk in humid rooms. (6.8)
● 7/8 in honeycomb aluminum core
○ Particleboard core
6.9Tempered glass markerboards shall be fabricated from low-iron glass of the thickness scheduled and, where magnetic function is required, shall be furnished with a continuous steel backing panel.
NOTE Standard tempered glass markerboards use 1/4-inch (6 mm) low-iron glass; low-iron is specified so the writing surface reads clean white rather than the green cast of ordinary float glass. (6.10)
● 1/4 (6 mm) tempered low-iron
6.11The finished writing surface shall not deviate from a true plane by more than 1/8 inch over any 8 feet of length when the unit is installed.
6.12The writing surface shall resist ghosting under normal dry-erase use, demonstrated by the manufacturer's documented ghost-resistance procedure for the specified surface.
7 Tackboards
NOTE A tackboard is a pinning surface, and its face material is chosen for the room's moisture exposure and aesthetic rather than for durability of writing; the four common faces range from utilitarian burlap to self-healing washable vinyl to natural cork to designer fabric. (7.1)
NOTE The available tackboard faces serve different conditions: (7.2)
- Type I burlap — economical woven jute face for low-visibility utility locations.
- Type II self-healing vinyl — washable, mildew-resistant vinyl that closes pinholes; the durable choice for healthcare and high-moisture or high-traffic locations.
- Type III natural cork — resilient natural-cork face with a warm appearance; the traditional classroom and office choice.
- Type IV fabric — woven fabric face over a backing, available in a wide designer color range and in acoustical and non-acoustical builds.
7.3The tackboard face material shall be as scheduled for the room's exposure, with self-healing vinyl specified where the surface is exposed to moisture, frequent cleaning, or infection-control wipe-down.
○ Type I burlap
○ Type II self-healing vinyl
● Type III natural cork
○ Type IV fabric
7.4Self-healing vinyl tackboard face material shall weigh not less than 21 ounces per lineal yard.
NOTE The 21-ounce minimum weight is what separates an institutional-grade vinyl face that closes pinholes for years from a light commodity vinyl that tears at the pin line; specifying the weight, not just "vinyl," is what enforces the difference. (7.5)
7.6Fabric tackboard color, where shown as selected by the Architect, shall be confirmed early enough to accommodate the manufacturer's lead time for non-stock fabrics.
NOTE Custom and designer tackboard fabrics commonly run an 8-to-12-week lead time; a late "as selected by Architect" fabric is a frequent cause of schedule slippage on occupied-building work, so the selection deadline belongs on the submittal schedule, not in the punchlist. (7.7)
● Manufacturer standard stock color
○ Architect-selected designer fabric
Per drawings — finish schedule
7.8The tackboard core shall be a rigid laminated assembly faced as specified and shall hold pins without splitting or losing pinning resistance over its service life.
7.9Where a cellulosic fiberboard core is furnished, it shall conform to ASTM C208 for cellulosic fiber insulating board.
● 5/8 in honeycomb aluminum core
○ Cellulosic fiberboard core (ASTM C208)
○ Particleboard core
8 Combination Units
NOTE A combination unit places a markerboard and a tackboard in one frame, side by side or stacked, so a single elevation covers both functions; it is specified as one assembly to keep the frame, trim, and accessories continuous across the two surfaces. (8.1)
8.2A combination unit shall be furnished as a single factory assembly with a continuous frame spanning both the markerboard and tackboard panels.
8.3The markerboard and tackboard panels within a combination unit shall each meet the surface and core requirements of their respective sections of this standard.
● Side-by-side (markerboard and tackboard horizontal)
○ Stacked (markerboard over tackboard)
○ Markerboard center with tackboard ends
Per drawings — interior elevations
● Predominantly markerboard
○ Equal split
○ Predominantly tackboard
9 Frames, Trim, and Accessories
NOTE The frame and trim are the visible edge of every unit and the part most often left to default; an anodized-clear aluminum frame reads silver, which may or may not be the intended look against the room's millwork and wall color, so the finish is a coordinated selection rather than an afterthought. (9.1)
9.2Aluminum frame and trim extrusions shall be Alloy 6063 conforming to ASTM B221.
9.3Anodized aluminum frame and trim shall receive a clear architectural anodic finish, Class II minimum (0.010 mm), conforming to AAMA 611.
NOTE Clear anodized Class II is the 80-percent-case default frame finish; painted aluminum to match millwork is a legitimate choice but requires an early color selection and may extend lead time, so it is a deliberate decision rather than a substitution at submittal. (9.4)
● Clear anodized aluminum (AAMA 611 Class II)
○ Painted aluminum (color as scheduled)
○ Satin stainless steel
○ Wood veneer (species as scheduled)
Per drawings — finish schedule
9.5A marker or chalk tray shall be furnished with each markerboard unless the Contract Documents specifically omit it.
NOTE The marker tray is the accessory most often assumed and least often specified; it is listed as an "accessory" in manufacturer literature, so a board ordered without explicitly calling out the tray arrives without one and becomes a punchlist item. (9.6)
● Continuous marker tray (full width)
○ Continuous chalk tray (full width)
○ No tray
NOTE A display rail (map rail) is a hook-bearing extrusion for hanging maps and charts; a projection screen receiver is a track for a roll-down screen — they look similar at the top of a display wall, so each shall be specified explicitly to the function it serves. (9.7)
9.8Where a map or display rail is shown, it shall be furnished as a continuous extrusion with map hooks and, where scheduled, a cork insert strip.
9.9Where a projection screen receiver is shown at the head of a display wall, it shall be furnished as a continuous mounting track sized for the screen specified under the audiovisual scope, and shall not be substituted by a map rail.
☐ Map / display rail with hooks
☐ Cork insert strip
☐ Projection screen receiver track
☐ End map hooks
10 Bulletin Board Cabinets
NOTE A bulletin board cabinet is a tackboard behind a glazed, lockable door — a display case for posting notices that must stay put, used in corridors, lobbies, and controlled-information locations where an open tackboard would invite tampering. (10.1)
10.2A bulletin board cabinet shall be furnished as a complete assembly comprising a tackboard back panel, a frame, a glazed swinging or sliding door, and locking hardware.
10.3The cabinet glazing shall be tempered glass where the cabinet is located within 10 feet of an operable window, a skylight, or other high-ultraviolet or impact-prone location.
NOTE Acrylic glazing is acceptable in interior, low-UV locations but yellows and scratches under ultraviolet exposure; tempered glass is required near windows and skylights for both clarity retention and impact resistance. (10.4)
○ Tempered glass
● Acrylic
10.5Where locking hardware is specified for a bulletin board cabinet and electric latching is required, the electric strike shall conform to ANSI/BHMA A156.31.
● Keyed cam lock
○ Keyed cylinder lock
○ Electric strike (ANSI/BHMA A156.31)
○ No lock
11 Panel Systems
NOTE Panel systems trade a fixed board for flexibility: a modular rail lets markerboard and tackboard panels be swapped or rearranged, and a sliding multi-panel track multiplies writing surface in a fixed wall width by overlapping panels that slide aside. Both introduce structural and accessibility demands a fixed board does not. (11.1)
11.2A modular support-rail system shall be furnished with a continuous wall-mounted extrusion and interchangeable markerboard and tackboard panels that clip or slide onto the rail.
11.3The assembled projection of a modular rail system, measured from the wall plane to the outermost panel face, shall be verified against the 4-inch ADA protrusion limit for any portion mounted between 27 inches and 80 inches above the finished floor.
11.4A sliding multi-panel system shall be furnished with a wall-mounted track sized for the number of overlapping panels scheduled and shall operate smoothly across its full travel.
NOTE Sliding-panel and folding-panel systems hang their weight from a top track, which requires structural header blocking at the top of travel; if that blocking is not shown on the structural or framing drawings it surfaces as an RFI at rough-in, after the wall is closed. (11.5)
● Fixed single panel (no system)
○ Modular interchangeable-panel rail
○ Sliding multi-panel track (2 to 4 panels)
○ Folding multi-panel
Per drawings — interior elevations
12 Portable Visual Display Units
NOTE A portable unit is a freestanding board on a base or casters, specified where the program needs a writing surface that moves between rooms or rolls out of the way; it carries no wall-mounting or blocking obligations but shares the same surface-material logic as a fixed board. (12.1)
12.2A portable visual display unit shall be furnished as a freestanding floor-standing assembly with a stable base and, where scheduled, locking casters.
12.3A double-sided portable unit shall provide an independently specified writing or tackable surface on each face.
○ Single-sided markerboard on casters
● Double-sided markerboard on casters
○ Markerboard one side, tackboard other side
○ Floor easel
● Locking swivel casters
○ Fixed glides
○ Tripod easel legs
13 Sizes and Configuration
NOTE Visual display units are sold in a small set of standard module sizes that align with classroom and conference-room walls; specifying a standard module avoids the cost and lead-time penalty of a custom size, while a custom size is reserved for walls that genuinely cannot accept a standard module. (13.1)
13.2Units shall be furnished in the standard module width and height scheduled, with custom sizes used only where a standard module cannot fit the available wall.
NOTE The 96-inch by 48-inch unit is the 80-percent-case classroom and conference-room module; widths of 36, 48, 60, 72, 96, 120, and 144 inches and heights of 36, 42, and 48 inches are the standard catalog range. (13.3)

● Surface-mounted
○ Recessed (flush to wall plane)
○ Modular support rail
○ Portable (freestanding)
Per drawings — interior elevations
14 Coordination, Blocking, and Backing
NOTE A visual display unit is only as well-mounted as the wall behind it, and the heaviest units fail the most quietly: a large-format glass markerboard can exceed 10 pounds per square foot and will pull out of unreinforced gypsum board, so the blocking is part of the specification, not an installer's improvisation. (14.1)
14.2Continuous wood or steel blocking shall be provided in the wall framing at every wall-mounted unit, coordinated with the gypsum board assembly trade (Gypsum Board Assemblies) before the wall is closed. 14.3Blocking and backing for heavy units — large-format glass markerboards and stacked panel systems — shall be sized for the unit's actual weight rather than for a generic light fixture, and the required blocking shall be shown on the framing drawings.
NOTE Coordinating blocking late, by addendum, is the classic miss on this section; the blocking requirement is cheap to show on the framing drawings and expensive to add after the wall is rocked, so it is coordinated at framing, not at trim-out. (14.5)
15 Installation
15.1Units shall be installed plumb, level, and true to the lines and elevations shown, with the writing or display surface in a single plane across multi-panel runs.
15.2Units shall be anchored to the coordinated blocking or backing with the fasteners specified by the manufacturer for the substrate.
15.3Units shall not rely on gypsum-board anchors alone where blocking is required.
15.4Mounting heights shall match the interior elevations and shall satisfy the accessibility reach and protrusion limits established in the Regulatory and Accessibility Requirements section.
15.5Field-cutting or field-drilling of porcelain-enamel or glass writing surfaces is prohibited; units requiring penetrations shall be factory-fabricated to the required configuration.
NOTE A porcelain or glass surface that is drilled or cut in the field cracks the fired enamel or the temper and voids the warranty; any required cutout is a factory operation, which is why the configuration must be finalized before fabrication rather than adjusted on site. (15.6)
15.7Adjacent units intended to read as a continuous run shall be installed with consistent, hairline joints and aligned trim.
16 Cleaning and Protection
16.1Units shall be protected from damage and from construction dust and overspray after installation and until Substantial Completion.
16.2Protective coverings and any factory-applied film shall be removed and the writing and display surfaces cleaned in accordance with the manufacturer's instructions immediately before Substantial Completion.
NOTE The wrong cleaner ruins the right surface: abrasive pads and solvent cleaners that are fine on one surface scratch or dull another, so the cleaning agents permitted and prohibited for each surface are carried in the maintenance data rather than left to the custodial staff to discover. (16.3)
17 Delivery, Storage, and Handling
17.1Units shall be delivered in the manufacturer's protective packaging, with each unit labeled to identify its type, size, and intended location.
17.2Units shall be stored flat or on edge as directed by the manufacturer, indoors, protected from moisture, and not stacked in a manner that distorts the writing surface or dents the frame.
17.3Glass markerboards shall be handled and stored on edge in protective crating until installation to avoid surface contact damage and edge chipping.
18 Warranty
NOTE Surface warranty length is the clearest signal of surface quality, and the spread is large — a half-century for porcelain, a decade for glass, a few years for melamine; specifying the warranty makes the lifecycle-cost argument concrete rather than rhetorical. (18.1)
18.2The manufacturer shall warrant each writing surface against defects in material and workmanship for the period appropriate to the specified surface, and shall furnish the executed warranty as a closeout submittal.
18.3Porcelain-enamel-on-steel writing surfaces shall carry a manufacturer's surface warranty of not less than 50 years; tempered-glass surfaces not less than 10 years.
● 50 years (porcelain enamel on steel)
○ 10 years (tempered glass)
○ 5 years (painted steel)
○ 1 to 5 years (melamine)
18.4The manufacturer shall warrant frames, trim, and accessories against defects in material and workmanship for not less than one year from Substantial Completion.
19 Spare Parts
NOTE Spare accessories — map hooks, cabinet keys, and a marker-tray or cork-strip section — are inexpensive at the time of purchase and effectively unobtainable as a matched item years later, so a small spare stock is specified up front rather than chased after a loss. (19.1)
19.2The Contractor shall deliver to the Owner the spare accessories scheduled below, packaged and labeled, before Substantial Completion.
☐ Map hooks (per cent of installed quantity)
☐ Bulletin cabinet keys (two per keyed group)
☐ Spare marker / chalk tray section
☐ Spare cork insert strip section
☐ Touch-up frame finish
