Frequently Asked Questions About Spray Foam Insulation

How does spray foam insulation work?

Spray foam insulation is made by mixing chemicals that react with one another to create a foam. Spray foam is applied to surfaces as a liquid and then expands on contact, creating a foam barrier that insulates and effectively fills all cracks and voids. There are two main types of spray foam insulation, open-cell, and closed-cell.


What is the difference between open-cell and closed-cell spray foam insulation?

There are two main types of spray foam insulation, open-cell, and closed-cell. Open-cell spray foams use less material, is less costly, and has a soft, sponge-like texture that retains a continual air seal throughout a building. Meanwhile, closed-cell spray foams are denser, can accommodate code requirements in narrow spaces, and have a rigid texture which adds wall-racking strength and impact resistance to your property. The goals that you want to achieve with your insulation will determine what kind of spray foam is best for your property.


Can I install spray foam insulation on my own?

No. We do not recommend DIY spray foam installation. The proper installation of spray foam insulation requires complex equipment and extensive training in safe installation methods. Further, since spray foam insulation expands quickly and adheres to any surface, it must be applied in a timely and expert manner. An uneven distribution of spray foam can lead to immediate and future problems. 


When does spray foam insulation need to be installed?

Spray foam insulation should be installed after the installation of rough plumbing, heating and air conditioning ducts, and electrical wiring, but before the interior walls are finished in a new construction project. Spray foam insulation can also be added to the inside of roofs and under the floors of homes and buildings that have already been built.


Does spray foam insulation work better than traditional types of insulation?

Yes. Spray foam is the best insulation for your home or business. Spray foam is incredibly dense and is bonded tightly, allowing for a secure air and moisture barrier. Further, because spray foam insulation can provide a seamless coverage, the energy efficiency of your home or commercial property will increase, saving you money on your electricity bill.
