About this detail

A non-rated partition wall base sits on a mass timber floor assembly. The structural floor consists of 5-ply cross-laminated timber panels topped with a 1/4-inch thick acoustical underlayment and 1 1/2 inches of gypsum concrete. The partition track is fastened through the gypsum concrete into the timber deck using 6-inch long Simpson SDS screws spaced at 32 inches on center, requiring pre-drilling through the gypcrete. A 1/4-inch non-hardening resilient acoustical sealant is applied at the base of the partition on each side, with edge beads and resilient base installed as scheduled.
