Prioritising safety, compliance, and comfort
Safety is an essential consideration for every building and regulations for high-rise developments are stricter than ever before. Approved Document B has tightened the restrictions on using combustible materials in certain build-ups and the Building Safety Act (2022) has increased scrutiny of high-risk buildings. And safety is just one of several factors in your specification. We offer a wide range of ceiling, wall, and non-combustible* insulation solutions that can contribute to fire safety, alongside thermal and acoustic performance. Our complete, tested systems are also available to help streamline your specification.

A fully filled cavity with DriTherm® Cavity Slabs will meet the requirements of the Building Regulations 2010 Approved Document B (Part 6), so cavity barriers won't be required. DriTherm® Cavity Slabs have the highest Euroclass A1 reaction to fire classification, in accordance with BS EN 13501-1: 2007. As the insulation fully fills the cavity, no cavity barriers are required. For more details, see BBA Certificate 95/3212.
