150mm Isover Cavity Wall Slab (CWS) 36 3.28m²/Pack (20/Plt) 5200625453


Designed for thermal efficiency and superior performance, the 150mm Isover Cavity Wall Slab (CWS) 36 is a premium glass mineral wool insulation solution. Engineered for use in partially filled masonry cavity walls, this product provides excellent thermal and acoustic performance while supporting modern energy-saving construction standards.


Product Features/Specifications: 

The CWS 36 slab features a semi-rigid texture, light yellow colour, and is manufactured from high-quality glass mineral wool. Each slab fits snugly between wall ties without slumping, ensuring consistent thermal insulation throughout the wall cavity. Its hydrophobic properties help resist moisture ingress, making it ideal for UK weather conditions.


Detailed Product Benefits:  

The Isover CWS 36 150mm slab is built to deliver low thermal conductivity (0.036 W/m·K), ensuring outstanding insulation performance that meets and exceeds Building Regulations. It is easy to install, cut, and handle—thanks to its semi-rigid composition—and maintains shape over time without sagging. With Euroclass A1 fire classification, it offers exceptional fire safety. Made from up to 86% recycled materials, this product is also an environmentally responsible choice for eco-conscious builds.


Applications and Versatility: 

Perfect for new builds and extensions, the Isover CWS 36 slab is specifically developed for use in partially filled masonry cavity walls in both residential and commercial settings. It is ideal for builders and contractors seeking efficient, easy-to-install insulation with a focus on performance, sustainability, and long-term value. Beyond thermal insulation, it contributes to acoustic control by dampening sound transfer between walls.
