An environmentally friendly home is a great benefit for builders, occupants, and the environment. Take an active role in helping reduce greenhouse gases, thus slowing the effects of global warming. By properly sealing a home the amount of oil that is needed to produce electricity and the carbon admitted into the environment is greatly reduced. Spray polyurethane foam insulation, because of its efficiency as an air sealer and waterproofing agent, has the potential to be a key component of the durability management strategy for a home. In addition to adding durability, spray foam contributes to projects' achievement of high levels of energy efficiency because of the high R-value per inch and the performance characteristics of foam.
