Spray Foam Insulation Complete Guide

Did you know? Spray foam insulation has a life span lasting anywhere from 80 to 100 years!

Spray foam insulation can be made of a combination of polyol resin and isocyanate, which, when combined, form a foam.

Alternatively, the spray foam insulation can be made of polyurethane, which is organic and the most common thing for spray foam insulation to be made of.

Spray foam insulation comes in high, medium, and low density. These different forms are used depending on the R-value that is desired.

Spray foam insulation also comes in two distinct types: open cell or closed cell. 

Closed cell spray foam insulation has a more rigid structure and, as such, tends to last longer than open cell.

How do you use it?

Spray foam insulation is normally used with a spray gun that looks similar to that of a spray gun used for painting.

The foam itself, when first sprayed, comes out fairly thin and normally white. After being sprayed, the foam begins to expand and take up more space.
