The different types of Spray Foam Insuation

Spray foam insulation is a hot item right now! From new construction to retrofit construction the product is available everywhere. But, what’s the difference? Here is a basic run down of spray foam insulation.

The main differences between open and closed cell foam are moisture permeability, R-Value, and flexibility. Closed cell foam is a moisture vapor barrier. It will not allow moisture to travel thru the foam. Open cell foam is not a moisture vapor barrier, and will allow moisture to pass thru it. Closed cell and open cell also have different R values. Although it is important, R-value should not be the determining factor when it comes to spray foam. Open and closed cell foam are both great insulation materials but are typically used in different areas of a home. Both can be used overlapping depending on the application needed. R values for Closed cell foam is around 7.0 per inch as compared to 3.7 per inch in open cell. However, both foams are excellent products for your home.

  1. This was a good read! My insulation has really helped cut down on energy use, but it’s getting old so I may update with spray foam. It has really helped in my basement along with waterproofing to keep it warm and dry.
