Cavity Walls

We manufacture a PIR insulation board that is suitable for partial fill cavity wall constructions up to 25m in height.

For new build projects, our board ensures you benefit from high standards of insulation without a great increase in the overall wall thickness - meaning internal habitable space is not compromised. This is an increasingly significant benefit as thermal regulations become more stringent, ensuring that the footprint of the building is not increased with an larger cavity, a necessary compromise with lesser performing insulations.

Our Eurowall Cavity wall insulation board is ideal for this application, and, if a lightweight block is used for the inner leaf construction, can meet the latest Building Regulation requirements with a single 130mm layer. When used within the masonry cavity walls constructed in accordance with BBA Certificate 02/3908, Eurowall Cavity will not prejudice the fire resistance properties of the walls.
