All the timber in your home needs to 'breathe', building regulations state in your attic a 50mm air gap is required between insulation material and the roofing felt unless the roof is counter battened where the foam can be sprayed directly on the roofing felt.
CPI Foam's E500 open cell spray foam and breathable vent card system have been tested in Irish climatic conditions and have received the coveted NSAI nsai agrément certificate. All our staff have been trained and certified to use all CPI products.
Most roofing systems in Ireland are not counter battened so its very important to maintain a 50mm air gap between the foam and roofing felt. We are able to achieve a continuous 50mm air gap by employing CPI Foam's unique breathable vent card system.
The card to attached to the rafters at the required 50mm from the felt. The foam is then applied to exposed rafters and the card. As the card is rigid it doesn’t warp or degrade like cardboard yet allowing water vapour to escape.
