Follow good safety/industrial hygiene practices during installation. Wear appropriate personal protective equipment. Read SDS and literature before specifi cation and installation. 19 LINEAR COMPONENTS USG 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. USG True Wood linear plank system installs on USG Donn® Brand Drywall Suspension System, and the typical layout for this system is Main Tees (DGLW26) installed 4 feet on center hung every 4 feet along the main and cross tees installed every 4 feet between the mains. For USG True Wood linear system, the linear planks are screw attached to the cross tees and run parallel to the main tees. USG True Wood linear planks are installed in a progressive fashion with the aesthetic felt toward 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. USG True Wood linear planks are screw attached with 1/2 wood lath 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 prepunch the grid flange to assure connection integrity. Use 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, two 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. 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.
