Mayplas MP552 Masonary Cavity Stop Sock – All Sizes

FIRESSOCK

Description

Mayplas MP552 Masonary Cavity Stop Sock  is designed to prevent passage of fire through concealed voids within the external fabric of a masonry wall construction.

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

The barrier is held in place under compression between the inner block work and outer masonry leaf.

Masonry Cavity Stop Sock 552 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 (Appendix A) as a “cavity stop”.
