Spray Foam Insulation is the best home insulating material you can use to seal your home.
Spray foam insulation is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes drilled in into a cavity of a finished wall.
Buildings with spray foam insulation routinely perform 30-50% better than buildings with traditional insulation materials.
Creating an air barrier with spray foam improves energy efficiency, keeping your home warmer during the winter and helping your cooling system keep pace with the summer heat. Spray foam virtually eliminates the largest source of energy loss in the average home – the 30 to 40% of energy typically lost through air leakage.
With traditional insulation materials, HVAC professionals typically need to install larger units which cost more to install and operate. The bottom line is that heating and cooling a home insulated with spray foam typically costs much less than an average home.
Spray foam insulation can be categorized into two different types: open cell and closed cell.
- Open cell foam insulation
Open cell is a type of foam where the tiny cells are not completely closed. Open cell is less expensive because it uses fewer chemicals. It is a very good air barrier but does not provide any type of water vapor barrier. It is much more sponge-like in appearance. It is often used for interior walls because it provides sound reduction. It is not recommended for outdoor applications.
- Closed cell foam insulation
Closed cell foam insulation is much denser than open cell. It has a smaller, more compact cell structure. It is a very good air barrier as well as a water vapor barrier. It is often used in roofing projects or other outdoor applications, but can be used anywhere in the home.
Benefits of Spray Foam Insulation include the following:
- Saves on energy costs
- Stops air and moisture infiltration
- Keeps dust and pollen out
- Makes your home more comfortable
- Adds strength to the building structure
- Reduces maintenance and wear of HVAC equipment
