About this detail

This assembly details a pipe and conduit penetration through a non-rated wall construction. The annular space around the piping is packed with 1-inch thick glass or mineral fiber insulation and sealed continuously on all four sides using a 1 1/4-inch diameter polyethylene foam backer rod or closed-cell neoprene sponge rod. Two continuous beads of non-hardening, resilient caulk are applied at the perimeter joints. A smaller conduit penetration detail similarly utilizes a 1-inch wide by 3/4-inch thick closed-cell neoprene strip with two continuous beads of non-hardening resilient caulk.
