Spray foam insulation is insulation that has been applied in liquid form, then expanded to make a thick foam. There are two types: open cell and closed cell spray foam insulation. Closed cell spray foam insulation, although more expensive and dense, is more effective at keeping out moisture and has a higher R value. Open cell spray foam insulation is less expensive, more affordable, and has lower R-value. It can also be used where closed cell foam cannot. Spray foam insulation can also be used in open and closed cell configurations to increase comfort and energy efficiency. Contact us to discuss the details of your project.
