Insulation

While pink fiberglass has been the mainstay of insulation for quite some time, newer, more efficient, and greener alternatives are widely available. Alex walks us through these alternatives: new types of batting (such as recycled denim), foam, and loose-fill (recycled paper cellulose). Alex talks to the providers of these alternatives to get the specifics on R factors, cost, durability and environmental impact. He also explores how insulation today can enhance air quality, seal the thermal envelope, and even add rigidity to a structure.
