150mm Superglass Superwall 36 Cavity Batt 1200mmx455m (3.28m2)

At Mitcham Builders Merchants, we supply high-performance 150mm cavity wall insulation that delivers exceptional thermal efficiency for both domestic and commercial projects. Manufactured from non-combustible glass mineral wool, the Eurowall+ range is a reliable choice for masonry cavity walls where insulation quality and safety are essential.

Suitable for full-fill applications up to 25 metres in height, and with no height restrictions for partial-fill, our 150mm cavity insulation provides flexibility for a wide range of builds. Approved by the British Board of Agrément (BBA) for use in all UK exposure zones, this insulation offers proven resistance against harsh weather conditions.

Each board is treated with a water-repellent additive to protect against moisture ingress, thereby helping to safeguard the structure and ensure long-term performance. Supplied at 455mm wide, the boards are designed for friction fitting between standard wall tie spacings, reducing the need for cutting and minimising waste on-site.

You can order online for same-day or next-day delivery across South London, or visit our Croydon branch to view our full range in person. Our knowledgeable team is always on hand to provide expert advice, ensuring you get the right insulation and building supplies for your project - all from a single trusted supplier.
