Rockwool Cavity Insulation

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.

The application involves blowing the granules into an external cavity wall. It is non-combustible nor does it rot or decay. Improving the acoustic performance of the wall, it is suitable for new builds as well as refurbishment projects.

  • Agrément certified for all exposure zones
  • Act as a cavity barrier
  • Water repellent
  • Excellent thermal and fire insulation
  • Superior fit against blockwork
