Spray Foam Insulation

Spray Foam Insulation Spray Foam Insulation is the right choice for any application!

If you’re not familiar with spray foam insulation, think of a foam coffee cup or a foam ice chest. Both products keep heat or cold in, while protecting the exterior from transferring temperature. Spray foam insulation does exactly the same thing.

Spray foam insulation doesn’t just insulate your home like fiberglass, cellulose or other insulation products – it also seals air leaks. Why does this matter? Air sealing prevents air from inside your home from escaping through the cracks and crevices in your home. These exist around recessed (can) lights, plumbing stacks, electrical wires, attic hatches or doors, around chimneys or flues, and duct chases. This means conditioned air you’ve already paid for stays in your home.

There are two types of spray foam insulation: open cell spray foam and closed cell spray foam. 

Open Cell Spray Foam
Open cell spray foam insulation works as an insulator and air barrier. The typical R value of open cell foam is 3.7 per inch. Other features of open cell spray foam insulation are:

  • it is vapor permeable
  • is able to accommodate seasonal movement
  • is not a food source for mold
  • dampens sound

Closed Cell Spray Foam

As with open cell spray foam insulation, closed cell spray foam works as an insulator and air barrier. An additional feature of closed cell spray foam is that it is solid. The cells of the bubbles remain intact (closed), which makes the product rigid. The closed cell composition and increased density contributes to a higher R-value than that of open cell foam. This can contribute to building stability during storms and high winds.
