Closed Cell Foam Insulation

Closed-cell spray foam insulation is one of the most efficient insulating materials commercially available, with aged R-Values above 6.0 per inch.

The description “closed-cell” comes from the cell structure of the finished insulation material. One cubic inch of polyurethane foam insulation contains millions of tiny plastic closed cells filled with Enovate® 3000, a non-ozone depleting blowing agent.

The blowing agent is captured within the cells which contributes to highly efficient insulating properties. In addition, closed-cell foam provides an inherent air barrier with low moisture vapor permeability, and excellent resistance to water. The density for closed-cell spray foam is approximately two pounds per cubic foot. The medium density foam provides sheer and racking strength to wall assemblies in building applications.

Closed-cell spray foam insulation systems, when properly installed, deliver energy savings of up to 45%.

Small imperfections in the building envelope (holes, cracks, gaps) not properly sealed will eventually lead to poor building performance or worse, moisture accumulation, allergen/pathogen growth, and very possibly structural failure. The solid nature and sealing capability of closed-cell spray foam, inhibits moisture-driven elements. Two inches of closed-cell spray polyurethane foam insulation will minimize air infiltration, exfiltration, convection, conduction and control solar driven moisture in the building envelope.
