50mm Rockwool Full Fill Cavity Batt are high-performance insulation products designed to fit snugly within the cavities of walls, providing excellent thermal and acoustic insulation. Made from natural volcanic rock, these batts are non-combustible and offer superior fire resistance, making them a safe choice for residential and commercial buildings. These batts ensure a complete fill that minimises thermal bridging and enhances energy efficiency. Their fibrous structure not only helps to retain heat during colder months but also reduces noise transmission, contributing to a more comfortable living or working environment. Rockwool insulation is resistant to moisture and does not promote the growth of mould or mildew, ensuring long-lasting performance. Easy to handle and install, these batts are an ideal solution for new builds and retrofitting projects alike, helping to meet building regulations and improve overall energy ratings. It is BBA for full fill applications in all exposure zones other than in very severe exposure zones with fair-faced masonry. The product is for use in new domestic and non-domestic buildings up to and including 25 meters in height.
