50mm Rockwool Cavity provides a completely reliable and cost-effective method of insulating new masonry cavity walls. The lightweight insulation batts considerably reduce heat loss without permitting water transmission from the outer to the inner leaf. The risk of condensation is also reduced and intermittent heating systems will be more effective.

Application:

Thermal insulation fully filling the cavity between two masonry leaves in external walls.
