Closed Cell

Closed Cell

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

Providing an energy-conserving solution to most structures

As a component of a systems approach to proper building envelope construction, closed-cell spray polyurethane foam provides exceptional performance in minimising heat transfer, moisture gain, air leakage and improving racking strength.

 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 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 vapour 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.
