How Do I Choose the Best Spray Foam Insulation?
Spray foam insulation is used in home improvement to increase the energy efficiency of the house, therefore lowering the heating and cooling costs. This type of insulation is released as a liquid that is composed of a polymer, usually polyurethane or modified urethane, and a foaming agent. The process of applying this insulation material is relatively simple. A nozzle is inserted behind the wall, under the floor or in the ceiling, via a small hole. The liquid is sprayed through the nozzle where it turns into foam and fills the area completely. There are three main types of spray foam insulation: three-pound foam (1.36 kg), two-pound foam (0.9 kg) and half-pound (0.23 kg) foam. Three-pound (1.36 kg) spray foam is mostly used in roof and attic insulation. It is the most expensive of the spray foams because it is also the most dense. The three-pound (1.36 kg) spray foam has an R-value (resistance to heat flow) of six, meaning it can trap gases denser than air. Depending upon the climate i
