Open Cell Vs. Closed Cell

Open Cell Foam

Spray polyurethane foam, commonly known as spray foam, is an insulating foam plastic that is spray-applied as a liquid and then expands to 120 times its liquid volume to insulate and seal all cracks, gaps, and joints it‘s applied to. It can cut heating and energy bills by up to 50%. Open-cell spray foam insulation has tiny cells which are not completely closed. Open-cell is usually less expensive because it is developed using fewer chemicals. Open-cell is superior as an air barrier, and is sponge-like in appearance. It is often used to insulate interior walls because it minimizes outdoor noise intrusion. It is not recommended for outdoor applications.

  • – Semi-rigid and soft to the touch
  • – Creates phenomenal air seal, eliminates drafts
  • – Provides excellent sound attenuation
  • – Less dense than closed cell foam
  • – Cost less than closed cell

Closed Cell Foam

Providing multipurpose protection in a single application, serves as air, water and vapor barriers all in one. By keeping out unwanted outside air and water, homeowners can enjoy comfort without worry of outside allergens and possible mold growth from moisture condensation or leakage. Our Closed Cell foam also provides an industry-leading flame spread rating of 0-5; which means, in case of a fire, the rate in which the flame burns and moves is slowed.

Close Cell foam is the perfect insulation solution for homeowners as it delivers quality insulation, cost effectiveness, and energy efficiency.
