Spray Foam Insulation

Spray foam insulation has residential, industrial and agricultural applications.  The product itself is polyurethane foam which is available in both Open and Closed Cell Foam Insulation.  Spray foam insulation is applied as a liquid using a foam gun. This liquid expands to fill all available space and hardens to form a tight seal.

Open Cell Spray Foam Insulation is a breathable product that is mainly used in both new build and existing residential properties.

Closed Cell Spray Foam Insulation is generally used for industrial, agricultural and commercial buildings. Closed Cell Insulation is not breathable but forms a solid skin where applied.

The product is certified by the NSAI and Cooper Insulation is an approved installer for CPI Spray Foam, one of the leading suppliers of spray foam insulation in Ireland. Further information is available in our Technical Library
