New MCRMA Guidance Document on Cavity Barriers

THE METAL Cladding and Roofing Manufacturers Association (MCRMA) has published a new Guidance Document, GD36 Cavity barriers for ventilated rainscreen façades.

Most modern buildings contain a multitude of concealed cavities and voids within or passing through walls, floors, ceilings and roofs. Effective fire stopping and cavity barriers are essential to restrict the spread of smoke or flames, and to maintain compartmentation. Cavity fire barriers are an essential element of fire protection.

Guidance Document on Cavity Barriers

The new document from the MCRMA sets out to consider the key questions about cavity barriers and offers advice for their correct specification.

It explains the difference between a fire stop and a cavity barrier, examines the regulations for the various parts of the UK, and gives installation recommendations.

The document is available for download on the MCRMA website.

Formed in 1990, the MCRMA supports systems manufacturers in the metal cladding and roofing industry. The association encompasses the needs of component manufacturer suppliers, stockholders, systems installers, independent roofing and cladding inspectors plus industry support services providers, all providing independent building envelope solutions for metal-based roofing and cladding systems, products and services.
