More About Our Cavity Insulation Products
Our range of cavity insulation slabs are high-performance rock mineral wool products available in various densities to meet your project’s specific needs.
Rockwool provides sound insulation slabs designed to control room acoustics while adding a thermal layer, making them ideal for areas such as home offices, bedrooms, and media rooms. These high-density, mineral wool slabs have non-directional fibers that trap sound waves and reduce vibrations, creating quieter interiors.
Isover cavity wall slabs provide thermal efficiency in external masonry cavity walls. These glass mineral wool slabs come with a water-repellent binder and are designed to fit securely between standard wall ties spacing, reducing heat loss and supporting energy savings.
