It is a polyurethane foam consists of two components to make up a final product used as insulation. One part polyol resin and one part isocyanate 1:1 ratio. Fusion, heat and pressure, combined with two components, make foam.
Closed Cell Spray Foam
Closed cell is the most effective foam insulation. Foam has different density in various applications. Home insulation would be 2lb density, agriculture foam for chicken houses use 10lb foam. Closed cells of the foam, trap gasses as a barrier to insulate. Closed cell foam offers a class II vapor barrier at 1.5″-2″ depending on the manufacture brand. Manufacture data sheets do not consider foam waterproof. However, the foam does resist moisture. Acting as an insulator, air barrier, vapor barrier (at 1.5-2″), the foam also assists with some light pest control.
Open Cell foam
Open cell foams generally tout a .5lb density, meaning .5lbs per cubic foot. Homes may use half pound foam as an insulation and an air barrier. It does not offer a vapor barrier attribute. If open cell gets wet, moisture may be absorbed. Vapor also drives into the foam in colder climates, referred to as vapor drive. Vapor drive occurs when humidity drives into the foam. Extreme temperatures outside and warm conditions inside, create the perfect scenario for vapor drive. This foam is a good product in the correct applications and in the right climate zones.
