Spray foam insulation is a form of spray plastic that can be used as insulation and an air-sealing barrier on roofs, corners, walls and contoured surfaces. It’s made by mixing different liquid components that react and quickly form the resulting foam. For more info see here.
Types of Spray Foam Insulation
There are two main types; open cell and closed cell (this can also be broken down and classified as low, medium and high-density foam insulation). The less expensive open cell insulation uses fewer chemicals and can be a very effective air barrier, but does not act as a water vapor barrier. Typically it is used for indoor insulation, and can also be a great sound barrier.
Closed cell foam insulation has a more dense and compact structure, and can also be used a water vapor barrier. Due to its structure, it can be used both indoors and outdoors (including roofs).
There are many benefits to using this type of insulation in your home or commercial building, but here are a few:
-First and foremost, in can lower your utility bills. This is because it stops air and moisture infiltration. Studies have shown that without proper insulation, a home can lose up to 40 percent of its total energy due to air infiltration.
-It adds additional strength to the structure of the building.
-It can help keep dust and pollen out
-It’s permanent and requires no additional maintenance
