You'll need the right caulk, gaskets, and airtight electrical boxes

摘要

A wide variety of caulks can be used for airtight drywall, but most experts recommend poly-urethane for sealing drywall to framing. Gaskets, however, outperform caulk in this application. Atrnleast three types of gaskets have been used successfully for airtight drywall sealing: open-cell foam gaskets (available from Denarco, manufacturer of Sure Seal gaskets; 269-435-8404), EPDM gaskets (photo left; www.conservationtech nology.com); or gaskets that are made from ripped lengths of foam sill seal.
