We supply 100mm cavity wall insulation, made to be extremely durable, safe, and thermally effective. As a Eurowall+ insulation, it is made of non-flammable glass mineral wool and can be used in both residential and commercial masonry cavity walls.

As a flexible choice for many projects, our 100mm cavity insulation can be installed up to 25 meters high for full-fill applications and has no height restrictions when used as partial-fill. It has demonstrated dependability even in harsh weather conditions and has been approved by the British Board of Agrément (BBA) for use in all exposure zones in the United Kingdom.

A water-repellent additive is incorporated into the boards to prevent water intrusion and help shield the structure from moisture damage. They are intended for friction fitting between typical vertical wall tie spacings and are supplied at a width of 455 mm. This speeds up installation, reduces waste on-site, and increases the efficiency of your project.
