Primary Types of Spray Foam insulation

  1. Open-Cell Spray Foam Insulation

As a result of having substantially less foam material than closed-cell foam, this type’s R-value is lower. Applying it causes it to grow to a thickness of around 3 inches. 3.5 to 3.6 inches, or a total of 10 to 11 inches, are lost in their R-value when it expands. It works best for soundproofing and economical insulation in climates with warmer winters and summers.

  1. Closed-Cell Spray Foam Insulation

In contrast to open-cell spray foam, this product is significantly denser. It ranges from 6.5 to 7 R-values per inch. Homes in climates where better thermal resistance is required are ideal candidates for it. Because it is denser, it can only expand to a thickness of roughly an inch. Multiple applications may produce an increased R-value.

Thickness for Open-Cell Spray Foam

  • Basement walls: 3 inches
  • Garage Insulation: 4 inches
