Spray foam insulation is a type of insulation that is applied as a liquid and then expands into a thick foam. There are two types of spray foam insulation- closed cell and open cell. Closed cell spray foam is denser and more expensive, but it is also more effective at preventing moisture infiltration and providing R-value. Open cell spray foam is less dense, less expensive, and provides less R-value, but it can be installed in areas where closed cell spray foam cannot. Both types of spray foam insulation are effective at reducing energy consumption and improving the comfort of your home or business. Call us today to discuss your project!
