Air Seal & Wrap Open Air Space Around Chimney in Simsbury, CT
Challenge
The building code requires that no combustible materials, including wood framing and insulation, be within 2" of a masonry chimney. this has left millions of homes with an airspace from the basement or crawl space right to the attic. Air that you paid to heat is continually leaking out of your home to the vented attic where it is lost. Results - a more drafty, uncomfortable home that's harder to heat, higher fuel and electric bills.
Solution
First, the space between the wood framing and masonry is flashed with metal and then sealed airtight with special high-temperature fire caulk. Then, completely fireproof "Rock Wool" insulation panels are installed around the chimney so that TruSoft™ cellulose insulation may be blown against the chimney. In some cases, unfaced fiberglass batts may be used instead of Rock Wool panels. "Chimney Wrap" leaves no gaps in the insulation around your chimney, and seals one of the biggest air leaks in your home. Results - Lower house air leakage, less heat loss, home is more comfortable and easier to heat, lower fuel bills.
