How do I form a cavity barrier?

The definition and requirement for a ‘cavity barrier’ is detailed within building regulations, e.g. Approved Document B, Scottish Technical Standard 2, and is not the same as ‘fire-stopping’ or ‘fire barrier’.

The fundamental performance required from a cavity barrier is to seal a cavity, this could be within a construction element e.g. partition cavity or to divide a larger space e.g. void above a ceiling, against the penetration of fire and smoke or to restrict its movement within a cavity.

The documents mentioned above, (ADB & Scottish Technical Standard 2) give further detail on cavity barrier requirements, fixing and installation.

Once the requirements are fully defined our Technical Consultants may be able to provide further guidance on the use of our systems to create cavity barriers. Fill in our technical enquiry form with full project details, for our Technical Support Team to review.
