SYSTEM
OVERVIEW
True Wood Systems True Wood Lay-In panels work just like traditional acoustical panels. Available in many
wood species and four perforation patterns.
True Wood Accessible Reveal panels install on a traditional suspension system and
provide a clean uninterrupted wood ceiling with complete access to the plenum. Available
in many wood species and four perforation patterns.
True Wood Linear is available in a variety of finishes and install directly to USG drywall
grid system, making the system great for large open spaces.
Sizes True Wood Lay-In panels and Accessible Reveal panels come in 2' x 2' and 2' x 4' sizes as
a standard.
True Wood Linear comes in a nominal 4" x 96" and 6" x 96" plank sizes and install with a
3/4 inch gap.
Suspension System True Wood Lay-In is available for both 15/16" DX™, 9/16" Centricee™ and 9/16" Fineline™
suspension systems. All Lay-In tiles have a 5/16" Shadowline™ or Fineline edge standard.
Panels may be field-cut at wall and columns but otherwise should be used in full
modules.
True Wood Accessible Reveal tiles installs on to 15/16" DX grid only, the reveal created
by the abutting tiles leaves a 3/8" gap that conceals the suspension system. Accessible
Reveal tile should be used in full modules but previsions can be made to accommodate
field-cut conditions
True Wood Linear is fastened directly to drywall suspension system and special
considerations have to be taken for access and field-cut conditions.
Perimeter Details Optional Compasso™ trim may be used with True Wood Lay-In and Accessible Reveal
ceilings for a finished appearance at exposed edges. See brochure IC400 in the USG
Specialty Ceilings Binder for more information.
True Wood perimeter trim can be used with all True Wood systems to ensure a panel
species and perimeter trim wood species match.
Acoustical Performance Perforated Lay-In and Accessible Reveal panels with a Acoustibond sound backer achieve
.60 NRC when installed in an enclosed plenum (18" depth min.). Available fiberglass
backing provides even greater acoustical performance.
Project Conditions Installation shall be done only when the temperature and humidity closely approximate
the interior conditions that will exist when the building is occupied. The heating and
cooling systems shall be operating before, during, and after installation, with the humidity
of interior spaces maintained between 25% and 55%.
Building environmmental conditions should be maintained in accordance with ASHRAE
Standard 62.1, 2013.
It is important that plenums have proper ventilation, especially in high moisture areas.
There shall be no excessive build up of heat in the ceiling areas.
Prior to the start of installation, all exterior windows and doors are to be in place, glazed,
and weather-stripped. The roof is to be watertight, and all wet trades' work is to be
completed, and thoroughly dry.

True Wood Products are FSC
Certified
Refer to CISCA Wood Ceilings Technical Guidelines for best practices on installing wood
ceilings.
Mechanical, electrical and other utility service installations above the ceiling plane shall
have been completed. No materials should rest against, or wrap around, the ceiling
suspension components or connecting hangers.
Wood shall be stored flat and level in a fully enclosed space. The Ceiling Panels shall be
stored off the floor. Care in handling must be exercised to avoid damage.
True Wood may be cut with a variety of tools including table saws, circular saws, jig
saws, and hole saws. Please follow the safety instructions issued by the power tool
manufacturer.
A miter saw or table saw are the best choices for maintaining a clean, straight cut. For
portable circular saws (Skilsaws) use either 24 or 40 tooth carbide blades to cut True
Wood.
For making holes for can lights, a hole saw is recommended. A jigsaw can also be used.
Use fine tooth blades that are specified for cutting veneers.

LINEAR
Components
Lay-out and site preparation The True Wood linear planks come finished on four sides with veneer and stain (if
applicable). The two short ends or butt ends are not finished and proper care must be taken
to assure these ends are either hidden or treated in the field to match the exposed face.
The True Wood linear plank system installs on USG’s Donn Brand Drywall Suspension
system and the typical layout for this system is Main Tees (DGLW26) installed four feet
on center hung every four feet along the main and cross tees installed every four feet
between the mains. For the True Wood linear system the linear planks are screw attached
to the cross tees and run parallel to the main tees.
The True Wood linear planks are installed in a progressive fashion with the aesthetic felt
towards the direction of the install. The spacing of the planks can be from zero to 7/8" of
an inch, great care should be taken to maintain the same spacing and blocks or gauges
should be used.
Some portion of the grid may be exposed, these areas should be treated in the field
with ‘flat black’ paint that is suitable for galvanized material and the environment of the
installation.
Plank Installation The True Wood linear planks are screw attached with 1/2 Wood Lathe screws from the
back of the ceiling through the flange of the cross tee and into the plank. It is critical that
the attachment of the planks be secure and that the fasteners are not ‘overdriven’, in some
cases it may be necessary to pre-punch the grid flange to assure connection integrity.
Using spring clamps to position the plank in place and assure its spacing and alignment.
Splice Plates: Place butt joints over framing members, otherwise framing angle or wood
can be used as a splice plate. Plan on using at least four 1/2" wood lath screws, 2 on each
side of the splice. True Wood can be used with a biscuit joiner as well to join butt ends.
Cutting butt ends at a 22-degree angle lessens the chance of seeing the exposed edge of
the panel line.
Finishing and Touch Up Touch up kits can be supplied by USG but similar material can be obtained from a local retailer
that carries wood finishing products. A sample should be tested for match and consistency.
