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.
