What is Foam-Lok?
Foam-Lok is a semi-rigid, non-toxic, spray foam insulation that offers added value as an air and moisture barrier solution that air seals wall, floor, and ceiling cavities to prevent air movement - including spaces around electrical outlets and light fixtures, at baseboards, and where walls meet windows and doors. So everything from frigid winter air to hot, humid summer air cannot seep through your walls to the inside, nor can your comfortable, interior air enter the walls to condense. By virtue of its low permeability to air, its adhesion to other building materials, and its flexibility, Foam-Lok provides value beyond insulation. It provides superior air leakage control, moisture control, and sound control - thus becoming a one-step insulation and moisture, vapor, and air barrier system. And, unlike fiberglass and other "loose fill" insulation methods that do not air seal building cavities, the air sealing characteristics of Foam-Lok provide virtually the same R-value in your home as it does in the laboratory where the listed R-value is measured.
How long has it been around?
Foam-Lok has been installed in various building structures for several decades. However, Foam-Lok's manufacturer LaPolla, has been making spray foam and coating products since the 1970s.
What is it made of?
Foam-Lok is a sugar cane polyol based formula that contains no formaldehyde, or ozone depleting gases like CFCs or HCFCs. Like other foam insulation products in its class, it has the texture (closed cell is almost as hard as wood) and look of angel food cake and is made up of millions of tiny cells. These cells are filled with air and provide permanent control of air and airborne moisture movement. Foam-Lok contains no materials that emit harmful gases. Unlike other foam insulation products, like Icynene, FoamLok is American made.
What are its advantages?
Aside from offering all the same benefits of other soft foam products, Foam-Lok is American made and therefore more affordable. As well as simplifying the construction process for the builder, Foam-Lok eliminates the major causes of building envelope problems, air-borne moisture movement and entrapment. Heating and cooling costs are typically reduced by 30 to 50%, and smaller, less expensive heating and cooling equipment can be used. The extreme comfort of a foamed home is a priceless benefit as well.
