STONESHIELD Timber Frame Cavity Barriers assist in satisfying requirements of guidance documents such as Approved Document B for England and Wales, Irish Approved Document B Fire Safety Volume 2 Technical Documents and The Scottish Technical Handbooks. The data shown below is from tests made to BS EN 1366-4:2021.

STONESHIELD Timber Frame Cavity Barriers have been tested with Timber Frame Cassettes, vertically and horizontally, both mid cavity to the edge of cavities around openings, and also at compartment lines sub-dividing cavities. They are also suitable for masonry to masonry applications.

STONESHIELD Timber Frame Party Wall Barrier is suitable for use at party wall lines.

STONESHIELD Timber Frame Cavity Barriers are stapled at 150mm centres to the inner OSB substrate at designated positions prior to brickwork being erected which then compresses the barrier within the cavity creating a seal against smoke and heat transmission.
