Spray foam insulation is the best choice to insulate your home under certain circumstances. There are two types of foam insulation: liquid foam insulation and foamed-in-place insulation. To insulate your home using liquid foam, the materials can be foamed-in-place, injected, poured, or sprayed. To insulate your home using foam-in-place, the materials can be blown on the surfaces of attics, into walls, or under floors. Doing so will reduce air leakage. Foam-in-place insulation can also be used effectively to insulate small cracks or holes.
If you’re interested in insulating your home with foam-in-place, it may be helpful to know there are two types: closed-cell and open-cell. Closed-cell foam uses closed high-density cells and is filled with gas to expand the foam so that it can easily fill the spaces around it. Open-cell foam uses lower-density cells and is filled with air rather than gas, so the insulation is more porous.
Deciding which type of foam material to insulate your home with depends on two factors: how you will use the insulation and your budget. Closed-cell foam will resist moisture and air leakage more effectively than open-cell foam, but the material is more dense and more expensive to install. Open-cell foam, on the other hand, is less dense and therefore less expensive to install, but may not be as effective resisting moisture.
Most foam materials are made of cementitious, phenolic, polyisocyanurate (polyiso), or polyurethane. Typically, foam materials now do not use chlorofluorocarbons or hydrochlorofluorocarbons due to their harmful nature to the ozone layer.
