Spray Foam Insulation

Spray foam insulation is a home insulation and air sealing product in one. The combination of insulation and air sealing increases comfort in homes and commercial buildings while reducing energy consumption. Spray foam insulation expands when applied. While fiberglass insulation can be combined with air sealing, spray foam insulation achieves both in one step.

BENEFITS OF SPRAY FOAM INSULATION

 

Spray foam insulation has a variety of benefits:

  • Increased Comfort – By stopping outside air infiltration, spray foam insulation prevents drafts and enhances acoustics.
  • Energy and Cost Savings – The combination of air sealing and insulation can help reduce monthly energy costs.
  • Reduced Outside Air Infiltration – Spray foam insulation seals air leaks and helps prevent outside air infiltration which can help reduce pollen, dust and allergens.
  • Durability to Last a Lifetime – Once applied, spray foam insulation will not shrink, sag or settle even if it comes into contact with water. Spray foam insulation sticks to a wide variety of materials including masonry, cement, metal studs, wood studs and rooflines.

 

TYPES OF SPRAY FOAM INSULATION

There are two different types of spray foam insulation, Open Cell Spray Foam and Closed Cell Spray Foam. They each have unique benefits.

Open Cell Spray Foam
Open cell spray foam insulation works as an insulator and air barrier. Weighing only 0.5 pounds per cubic foot, open cell spray foam gets its name from its broken cell structure. This allows air to fill the empty space inside the material. The typical R-value of open cell foam is 3.7 per inch. Open cell spray foam insulation is vapor permeable, dampens sounds and eliminates air infiltration.

Closed Cell Spray Foam
Closed cell spray foam also works as an insulator and air barrier. Closed cell spray foam is solid and more dense than open cell spray foam. The cells of the bubbles remain intact, which makes the material rigid. The closed cell composition and increased density contribute to a higher R-value than open cell spray foam. Higher density allows closed cell spray foam to contribute to building stability during storms and high winds.
