Preventing fire spreading through concealed voids is essential for improving safety and property protection. One of the best ways to achieve this is to correctly specify and install cavity barriers.
ROCKWOOL Cavity Barriers have been specifically developed to exceed minimum building regulation requirements for fire resistance in concealed wall cavities. They have been tested and assessed for up to 60 minutes fire resistance (Integrity and insulation).
Rockwool insulation products do not contain blowing agents with an ozone depletion potential (ODP) or global warming potential (GWP), are CFC-HCFC-HFC free and 97% recyclable. Compatible with most materials with which it is likely to come into contact in normal building and industrial applications. Will not react with metal components or cause loss of plasticiser from PVC cables and pipes.
