Warmth you can feel, with fire safety built in
Most people choose cavity wall insulation for one reason: a warmer home and lower heating bills. ISOCLAY® helps deliver that by filling the cavity seamlessly and providing strong thermal performance with a thermal conductivity. A big plus is that it is also fire safe. The mineral based insulation has limited combustibility, produces very little smoke, and does not create flaming droplets. Comfort and peace of mind, in one system.
Cavity wall insulation for masonry and prefab timber walls
ISOCLAY® is designed for seamless cavity insulation in double-leaf walls, improving thermal comfort and helping reduce heat loss in traditional brick homes. It is also a strong solution for modern prefab construction, including timber or gypsum based wall systems, where reliable cavity filling and strong fire performance are important. Thanks to its mineral based formulation and in situ application, ISOCLAY® supports consistent insulation results across both classic masonry cavities and lightweight prefab wall assemblies.

Effective insulation. Sustainable renovation.
ISOCLAY® is an innovative, mineral insulation material that is non-combustible and designed for simple, fast installation. It is particularly well suited for energy-efficient retrofit renovation of cavity walls. In many cases, the investment pays for itself within 4 to 7 years, making it both an environmentally and economically attractive choice.
By combining a hydrophobic, open-cell structure with a fast, reliable and seamless in-situ application, the system helps deliver consistent results. Unlike many conventional solutions, the foam can be disposed of with demolition waste without complex separation processes, or reused as a base layer material.
