Fire Protection for timber and steel frame and masonry cavity walls.
The cavity barriers can be used in both vertical and horizontal applications, providing an effective fire, acoustic and thermal barrier within external wall cavities and separating party walls.
ROCKWOOL TCB Cavity Barrier products have been created to provide excellent levels of fire stopping for timber frame and masonry properties. They have been designed to meet the minimum building regulation requirements for cavity barriers in concealed wall cavities, having been tested and assessed for up to 60 minutes’ integrity and insulation, thereby exceeding minimum requirements.
These cavity wall insulation products have been created from non-combustible stone wool and wrapped within a resilient polythene sleeve which acts to provide weather protection during installation. The TCBs are supplied in a red polythene sleeve.
Feature and benefits:
The Cavity Barriers have been tested and assessed for up to 60 minutes fire resistance (integrity and insulation) in accordance with BS 476 and BS EN 1366-4:2006 +A1 2010.
Rockwool Cavity Barriers comply with the generic description for cavity closers to prevent flanking noise transmission, along concealed cavities in both external and separating walls.
