Rockwool is a ‘breathable’ material with a vapour resistivity similar to air (5.9 MNs/gm). Rockwool Cavity Wall Batts therefore reduce the risk of condensation and allow natural drying out of the wall construction.
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. They will not react with metal components or cause loss of plasticiser from PVC cables and pipes.
