Thermal Insulation Cavity Batt
ROCKWOOL Thermal Cavity Batt 37 is a full fill stone wool insulation solution for masonry cavity wall constructions such as home extensions. Thermal Cavity Batt 37 is Euroclass A1 non-combustible, water repellent and vapour permeable, allowing the material to breathe, and will not harbour mould.
Thermal Cavity Batt 37 is easy to handle and install, allowing for a close fit against brick and blockwork. The ROCKWOOL cavity insulation is resistant to sagging or slumping over time, to deliver long term thermal performance.
In 2024, we’re updating the packaging used to protect our Trade Range products to improve its impact on the environment. We’ll be rolling this new look product packaging out across our range throughout the year, so soon you’ll start to see a change on the shelves.
