Spray Foam

Posted by on May 6, 2013 in Insulation | 0 comments

There are a couple different types of spray foam, open-cell spray foam and closed-cell spray foam. Both create great air seals when applied, but the difference is in R-Value. Open-cell has an R-Value of roughly 4.0 per inch. Closed-cell has an R-Value of roughly 6.2 to 7.0 per inch, depending on the manufacturer. The other main difference is that closed-cell spray foam can create a good vapor barrier, open-cell cannot. (Manufacturer: Lapolla Industries, Product: Foam-Lok)
