Firecode is a sealant that will control fire, smoke, and acous-tical issues in your buildings. A rust-red appearance makes it easy for contractors and in-spectors to identify. The acrylic latex-based product is intended for use as a joint sealant in fire-rated partitions and shaft walls, smoke barriers, sound-rated as-semblies, and through-penetra-tion fire-stop systems. Cost: $5.50 to $7. USG. 800-USG-4968. www.usg.com.
