Eco-Friendly Basement Insulation | This Old House

From the creator

Closed cell insulation plays a dominant role in the Concord house, and in the basement, there's a little trick to making it work with the concrete foundation. SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse. Because the Concord basement will be a living space, they take extra measures to insulate the space correctly. Richard Trethewey talks about how to best heat the home, which is difficult because of its unconventional layout and minimal wall space. He uses an unconventional zoning method, radiant floor heating, and a small duct high-velocity system. Charlie Silva shares his trick that allows the insulation to perform optimally and prevent thermal bridging. Insulation consultant Adam Piccirilli talks about the new environmentally friendly spray foam insulation required in most states.
