How Does Spray Foam Insulation Work
Spray foam insulation is an air barrier material that seals ceiling cavities against air movement. Unlike conventional insulation materials, spray foam fills cracks, gaps, and crevices on installation. It does not sag or break over time. This foam can be sprayed into an open cavity, like in new construction, attics, crawl spaces and rim joists. Find out in this infographic how spray foam insulation work.
