Changes to Approved Document B

2020 Amendments

September 2021

Due to these revisions, high-rise apartments will see changes to various design elements, including sprinkler systems and wayfinding signage placement. However, from Nuaire’s perspective, one of the most significant changes is the ban of combustible materials.

These changes to Approved Document B: Fire Safety ban the use of combustible materials both on and within the external walls of multi-storey buildings that contain one or more dwellings and have a storey 18m above ground level. Because of this, combustible materials such as ABS and HIPS are no longer suitable for use as grilles or outlets on high rise projects, so Nuaire have developed a new product range to meet the revised regulations.

Nuaire’s Solution

Earlier this year, we launched our range of metal air bricks.
