Attic Insulation Cork


Insulating your attic with spray foam insulation can reduce your heating bills by up to 50%.

Spray foam insulation is a polyurethane polymer and is chemically inert. This means that after it has been applied it does not pose any health and safety risk making it an ideal insulation material for attic conversions.

There are 2 types of spray foam insulation, open cell and closed cell. Open cell foam is used in all domestic or residential applications, closed cell foam is used in industrial or commercial applications.

We use CPI Foam's Ezero E-500 open cell spray foam insulation. The foam has been tested by the National Standards Association of Ireland (NSAI) and has received its coveted Agrément Certificate.

The NSAI has conducted rigorous test to make sure the foam performs to the manufactures specification and is tested in Irish climatic conditions.

Building Regulations

Section B.5.2.1 R 2 (a) of the Irish Building Regulation regarding the Conservation of Fuel and Energy – Dwellings Building Regulations 2011 states that: "Insulation between and below rafters, 50 mm ventilated cavity between insulation and sarking felt"

The reasoning behind this rule is to allow your roof timbers to 'breathe'. The escaping water vapour need to find access to the outside air without impediment so a 50mm air gap is required between roofing felt and insulation material.

Breathable Vent Card

In order to meet this regulation CPI Foam has developed a unique 'Breathable Vent Card System'.

The cards are attached to your rafters exactly 50mm from the felt.

The cards are rigid yet allow water vapour to escape while maintaining the integrity of the foams airtightness properties.

Note: If your roof has been counter battened creating an air gap between the felt and tiles then the foam may be applied directly to to the felt.
