Timber Frame Cavity Barrier 551 to Suit 50mm Cavity - 1HR

TIMBER FRAME CAVITY BARRIER 551 is designed to prevent passage of fire through concealed voids within the external fabric of a timber frame building.

The polythene enclosed rock fibre barrier is manufactured in bespoke sizes to suit the specified cavity width.

The barrier is stapled to the inner timber substrate prior to brickwork being erected and is compressed into the cavity.

Timber Frame Cavity Barrier 551 assists in satisfying requirements of guidance documents such as Approved Document B and The Scottish Technical Handbook.

The product reduces flanking sound transmission at separating wall and floor junctions and complies with Robust Detail as a “cavity stop”.

Suitable for both vertical and horizontal positioning to the edge of cavities, around openings, at separating compartment lines and to sub-divide cavities.
