Description

Cavities are created in many wall constructions to aid thermal insulation performance and to provide a moisture barrier. Such constructions are common in residential, public and commercial buildings.

Completely closing the cavity, for example with solid cavity barriers, can detract from its performance and can result in both thermal and moisture bridging and potential structural damage.

These wall cavities can form unrestricted chimneys which, if left unprotected, can allow fire to spread both vertically and horizontally around a building.

Cavities are subject to Building Regulations and most should be fitted with fire barriers to prevent the spread of fire via the open cavity.

To combat this ASTROFLAME as part of its continuing development of passive fire protection solutions has developed a Cavity Fire Barrier On a Roll.
