Description

MP551 Timber Frame Cavity Barrier and MP551 Timber Frame Party Wall Barrier are polythene enclosed stone mineral wool cavity barriers manufactured in sizes to suit customer specified cavity widths. MP551 Timber Frame Cavity Barriers assist in satisfying requirements of guidance documents such as Approved Document B and The Scottish Technical Handbooks. MP551 Timber Frame Cavity Barriers are suitable for both vertical and horizontal positioning to the edge of cavities such around openings, at compartment lines and to sub-divide cavities. MP551 Timber Frame Party Wall Barrier is suitable for use at party wall lines.

MP551 is stapled at 150 mm 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.
