150mm Isover Cavity Wall Slab (CWS) 32 2.18m²/Pack (15/Plt) – 5200619455


The Isover Cavity Wall Slab (CWS) 32 is a premium-quality, 150mm thick glass mineral wool insulation solution, specifically designed to deliver outstanding thermal and acoustic performance for masonry cavity walls. Engineered with both efficiency and sustainability in mind, it’s an essential choice for modern building projects that demand high performance and ease of installation.


Product Features/Specifications: 

Featuring a semi-rigid construction and a distinctive yellow appearance, the Isover CWS 32 is made from non-combustible glass mineral wool, offering robust thermal insulation alongside excellent sound reduction properties. Each pack covers 2.18m², and with 15 packs per pallet, it’s ideal for both small and large-scale projects.


Detailed Product Benefits:  

The Isover CWS 32 offers industry-leading thermal performance with a low thermal conductivity of 0.032 W/m·K, significantly reducing heat loss through external walls. Its semi-rigid composition ensures a snug fit within cavity spaces, minimising air gaps and maintaining insulation integrity over time. The product is also water repellent, reducing the risk of moisture ingress and damp issues, while its breathable composition supports optimal indoor air quality.


Manufactured using up to 75% recycled glass, Isover CWS 32 meets demanding environmental standards, making it a smart choice for eco-conscious builds. It’s also non-hygroscopic and resistant to fungal growth, contributing to the long-term durability and health of the building envelope.


Applications and Versatility:  

Designed for use in traditional masonry cavity wall constructions, this insulation slab is suitable for new builds, extensions, and renovation projects. It can be used in both residential and commercial settings, supporting compliance with Part L of the Building Regulations. Its ease of handling and friction-fit installation make it an excellent option for contractors looking to maximise efficiency without compromising on performance.
