Spray Foam Insulation
There are Two Types of Spray Foam Insulation:
Open Cell – Attics in homes
Closed Cell – Commerical Properties (Industrial Units/Offices – Sheds – Garages – Containers)
Open Cell Spray Foam – Attics in homes
Open cell spray foam expands to over 200 times its size when applied. It is ideal for use in your home attic as it fills every nook and cranny, creating an airtight envelope.
Coveted for its thermal conductivity and airtightness, open cell spray foam also allows your timbers to breathe, which is necessary to prevent damp and condensation build up. This is achieved because the cells are open, allowing water vapour to escape to the outside air.
Under Part L of the Irish Building Regulations, a 50mm air gap must be maintained between roofing felt and insulation material to allow water vapour to escape. We achieve this by attaching CPI Foam’s unique ‘breathable vent card’ to your rafters, then apply the spray foam insulation directly on the semi-permeable vent card.
Closed Cell: Outdoor Sheds – Commercial Buildings -Containers
Closed Cell Spray Foam
Closed cell spray foam insulation differs from open cell as its cells are closed and it expands to only 20-30 times size. It is used on any type of metal, asbestos wall or roofing and is mainly used in agricultural, commercial and industrial applications.
Closed cell spray foam has excellent thermal properties and can be applied on supporting beams to eliminate cold bridging. With new EU regulation for commercial and agricultural building expected soon, closed cell spray foam insulation provides a cost effect solution to these CO² emission inspired regulations.
