DESCRIPTION


Product Specification

Designed for use as a fire rated acoustic closer for party wall junctions. It helps reduce flanking sound transmission at the junction of internal separating and external cavity walls and complies with Robust Detail (Appendix A) as a “cavity stop”.

It is protected from moisture ingress by its integral DPC which must be installed with the DPC located to the rear of the outer masonry layer.

Consideration must be given to the overall width of the party wall construction – please contact Mayplas technical team for further guidance.
