Spray FoAm Insulation
Foam South offers two types of Spray Foam insulation: Open-cell and Closed-cell.
Open-cell foam is an air barrier, most commonly used in walls, floors, & attic rooflines.
Closed-cell foam is both an air barrier and a moisture barrier, most commonly used in areas of high moisture content, i.e. basements or crawl spaces.
The true power of spray foam in comparison to fiberglass insulation is its ability to eliminate air leaks, not necessarily its R-value. In most cases the first inch of spray foam does the majority of the work.
