Isover CWS 32 Cavity Wall Insulation is an outstanding solution for enhancing thermal performance in masonry cavity walls. Crafted by Saint-Gobain, a leader in sustainable building solutions, this cavity slab, is engineered to deliver superior insulation, compared to its couterparts, while prioritising environmental responsibility.

Made from premium quality glass mineral wool, Isover CWS 32 cavity wall slab insulation offer exceptional thermal conductivity, thanks to its reduced K-Value, ensuring optimal energy efficiency in residential and commercial structures. Cavity slabs are precisely designed to be 455mm wide to fit between standard wall ties, making installation stress and mess-free.

The innovative design of Isover cavity wall insulation allows it to seamlessly fit between wall tie spacing of the masonry cavity walls, maximising thermal insulation without compromising on space. Its non-combustible nature provides peace of mind, meeting the highest safety standards for construction materials.

Key Features

• Premium Quality Materials: avity insulation si amde of top-grade fibreglss or glass mineral wool.

• Optimal Thermal Conductivity: Engineered to deliver excellent thermal conductivity of 0.032 W/m.K, these cavity slabs enhance energy efficiency in buildings.

• Seamless Integration: Designed to fit flawlessly into masonry cavity walls, maximising thermal insulation without sacrificing space. Cavity slabs contain water repellent binder that help with condensation and moistire issues

• Non-Combustible Design: Isover CWS 32  cavity insulation achieves a Euroclass A1 Reaction to Fire classification, according to EN 13501-1., thereyby providing peace of mind with its non-combustible nature, meeting stringent safety standards for construction materials.

• Sustainable Production: Made from up to 75% recycled glass, these cavity slabs contribute to environmental sustainability while maintaining high-quality performance.

• Certified Performance: Isover cacity insulation is recognised by BBA (British Board of Agrément) for its exceptional thermal performance and durability. Cavity Wall Slab (CWS) 32 has been assessed by the BBA as fit for use in defined full fill and partial fill masonry cavity wall applications if installed, used and maintained as set out in the certificate

Applications: 

Isover cavity wall insulation can be used to insulate:

• External Walls - for full fill masonry cavity walls insulation
• Partial Fill Masonry Cavity Wall insulation as well
