Using spray foam insulation is an effective way to increase the energy efficiency of your home. It offers a higher R-Value than other insulation materials such as fiberglass and cellulose. The R-Value is a rating based on the effectiveness of the insulation material to reduce heat flow in winter and cold air flow in summer.
The R-Value of spray foam is determined by the density and thickness of the material. Spray foam is sprayed into the spaces between the studs in walls, ceilings, and attics. It is a good option to use in new construction or in existing homes, pole barns, and commercial buildings. The spray foam will expand to fill the open space and seal nooks and crannies. It is a great choice to insulate rim joists, walls, and attics because it will create a tight barrier to prevent vapor and moisture from passing through the wall and damaging your building’s structure.
The Green Choice: Environmental Benefits of Spray Foam Insulation
Spray foam insulation is an extremely effective insulator, however, the chemicals used to make the product have a high global warming potential (GWP) compared to carbon dioxide. Fortunately, many manufacturers have started to switch to low-GWP blowing agents for their spray foam products, which is an essential part of the green building transition.
The best way to install spray foam is to hire a professional technician to do the work. It is recommended that homeowners vacate the home during the spraying and curing process, which can last 1-3 days. This is because spray foam insulation off-gases large amounts of volatile organic compounds (VOCs) during the spraying and curing process.
