CavityStopSock
Description

ARC Cavity Stop Sock restricts the spread of smoke and flames within external masonry walls, as well as minimizing the effect of flanking noise pollution at wall junctions. The barriers are manufactured from low-resin, non-combustible rock fibre mineral wool insulation and are sleeved in polythene for on-site protection.

It is designed to be compression-fitted within a masonry cavity as the brick and block work progresses; no mechanical fixing is required.

Features:

  • Up to four hours' fire integrity.
  • Specified in semi-detached houses, apartments and major projects.
  • Complies with Robust Detail Part E and Building Regulations (E&W).
  • Can be manufactured to suit cavity widths of up to 300 mm.
  • Easy to install.
  • BRE Green Guide 'A+' rating.
  • Manufactured under ISO 9001- and ISO 14001-certified 'Quality and Environmental Systems'.
