drywall-wood framed systems

Section Pages Good Design Practices 15 Introduction The basic gypsum drywall assemblies described herein offer economical, quickly erected walls and ceilings on wood framing. Excellent sound attenuation at low cost is provided when gypsum panels are resiliently attached. The assemblies are likewise suitable for wall furring and exterior soffit applications. Also designed for wood-frame construction are USG Area Separation Fire Walls/Party Walls fire-rated gypsum drywall assemblies for multi-family housing (see separate System Folder SA925) and Sheetrock Brand Vinyl-Covered Gypsum Panels...

Drywall/Wood Framed Systems Single layer In single-layer ceiling assemblies, SHEETROCK Brand Gypsum Panels are applied across the supports and fastened with nails or screws. Nails are spaced 6Љ to 7Љ o.c. (6Љ for fire-rated construction); 1-1/4Љ Type W screws are spaced 12Љ o.c. Where no fire rating is required, adhesive nail-on fastening improves bond strength and reduces face nailing. Resilient attachment Resilient channel systems offer fire-resistant wood joist floor/ceiling assemblies having highly efficient sound isolation at low cost—qualities particularly needed in apartments, motels and other...
