Rockwool Cavity Insulation

You can trust Rockwool Cavity for a trustworthy and cost-efficient method for insulating new masonry cavity walls. Lightweight insulation application brings down heat loss by a considerable extent, with no water transmission from the outer to the inner leaf. As the risk of condensation is low, intermittent heating systems get more effective.
