Open-cell is usually less expensive because it is developed using fewer chemicals. Open-cell is superior as an air barrier and is sponge-like in appearance. It is often used to insulate interior walls because it minimizes outdoor noise intrusion. Closed-cell spray foam insulation is a higher-density foam than open-cell. The structure of the actual cells is more compact. It is both an air barrier, water-resistive, and vapor barrier. Closed-cell can be installed anywhere in the home Contact us Call : (941)-426-1040 Email: jwinsulation@yahoo.com Fax: (941)-426-9060 Mailing address: 5468 Cold Spring Lane North Port, FL 34291 © 2016 JW Insulation.
