ROCKWOOL Cavity Batts provide thermal protection for external masonry walls, and thermal and sound protection within masonry party walls, between dwellings. The batts are quick and easy to accurately cut, and provide a great fit; reducing installation time, avoiding gaps and cold spots, and maximising long-term performance. ROCKWOOL Cavity Batts are also used in masonry party walls to prevent the thermal bypass effect, and so achieve a zero U-value, while also providing the required sound protection and fire resistance.

Acts as a cavity barrier.
