Air-Lok Spray Foam Insulation

The first type of spray foam insulation is open cell. As the name suggests, open cell insulation consists of small pockets that aren’t completely enclosed. These foams expand a lot (up to three inches per pass), and the dried foam remains relatively soft and flexible. These products typically use water or carbon dioxide as the propelling agent, making them less harmful to the environment than their closed-cell counterparts. Open cell foam creates an effective barrier against air movement and sound. It’s useful in walls, ceilings, and roofs. However, due to the open cells, this foam is more likely to absorb moisture and vapor, so it can require the addition of a vapor barrier on the inside of the foam in many applications.

Cost will depend on the amount of labor required during installation. Labor costs often lie between $0. 95 to $2 per square foot. In addition, the materials required for insulation may also add to your final cost. There are several methods through which insulation can be done. Spray foam: this involves insulation foam being applied directly to surfaces of interest using a spray gun. Foam board: consists of caulking and furring stripes being applied on walls using an adhesive. Loose fill insulation: this method uses a machine that applies fiberglass, cellulose, and mineral insulating materials on surfaces of interest.
