We stock 75mm cavity wall insulation that’s designed for excellent thermal performance, durability, and safety. Made from non-combustible glass mineral wool, this Eurowall+ insulation is suitable for use in masonry cavity walls in both domestic and non-domestic buildings.

It can be installed up to 25 metres in height for full-fill applications, with no height restrictions when used as partial-fill, making it a versatile option for many projects. Approved by the British Board of Agrément (BBA) for use in all UK exposure zones, it offers proven reliability even in challenging weather conditions.

The boards include a water-repellent additive to resist water ingress, helping to protect the structure from moisture damage. Supplied at 455mm wide, they are designed for friction fitting between standard vertical wall tie spacings. This not only speeds up installation but also reduces on-site cutting and waste, making your project more efficient.

Whether you’re looking for 75mm cavity insulation for new builds or refurbishments, our high-quality Eurowall+ range delivers performance you can trust.
