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.
