SPRAY FOAM INSULATIONSpray Foam Insulation

What is Spray Foam Insulation? Spray foam insulation is a mixture composed of isocyanate and polyol resin that comes together at the tip of a gun, where it 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. There are two forms of spray foam insulation; open cell and closed cell.

Open cell foam insulation Open cell is a type of foam where the 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 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 as an outdoor barrier.

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 and works as a water vapor barrier. It is often used in roofing and other outdoor applications, but can be used anywhere in the home.

Why Spray Foam? Spray foam helps your home in three ways: 1- its high R-Value gives great thermal performance, so it minimizes hot and cold spots that can make your home uncomfortable and lower the efficiency of your heating and cooling systems. 2- Spray foam provides added integrity to your walls. 3- Spray foam acts as a moisture vapor barrier to help reduce the risk of moisture in the wall cavity, this reduces mold, mildew and wood rot.

Why is Air Sealing so important? If spray foam insulation is applied without proper air sealing, the home can lose efficiency through air leakage. This is one of the main causes of hot and cold spots that can cause a home to be uncomfortable. As with any building product, insulation is only as effective as its installation. Properly insulating and sealing your homes with spray foam can help lock in 20% or more of your cooled or heated air, making it a greener alternative.
