Invest in Spray Foam Insulation
Spray Polyurethane Foam is an insulation drastically different from any other form. It can form a continuous air barrier on walls, roofs, around corners, and on many surfaces in and around a home or building. It is created on-site by mixing two chemicals that react quickly to create a rigid foam. It not only insulates, but seals gaps, and some foams can form a barrier against moisture and vapor.
