Insulation Slabs

About

Insulation Slabs Insulation slabs are a flexible, semi-rigid form of insulation used across a wide range of construction applications. Unlike rigid boards, slabs are designed to be easily cut and friction-fitted into place — making them particularly well-suited for stud walls, between joists, and rafter insulation where a snug fit is essential to avoid thermal bridging. What Are Insulation Slabs Used For? Insulation slabs are commonly used in the following applications: Stud wall insulation — friction-fitted between timber or metal studs for thermal and acoustic performance Floor insulation — between joists in suspended timber floors Rafter insulation — between rafters in pitched roof build-ups Acoustic partitions — higher-density slabs for sound reduction between rooms Mineral Wool Insulation Slabs The majority of insulation slabs are manufactured from mineral wool (glass wool or rock wool). Mineral wool slabs offer excellent thermal and acoustic properties, are non-combustible, and are easy to handle and install on site. Rock wool slabs tend to have higher density and better acoustic performance, while glass wool slabs are lighter and ideal for general thermal applications.
