High Performance Partial Fill Cavity Slab
The ROCKWOOL High Performance Partial Fill Cavity Slab is a semi-rigid insulation solution designed for masonry cavity wall construction.
It is Euroclass A1 rated and has been designed to provide thermal performance and ease of installation, with the dual density absorbing irregularities on the inner leaf and provide a robust outer surface to fix retaining clips onto. These features in turn support the longevity of the external wall construction by delivering long-term energy efficiency and minimising heat loss through gaps in the insulation layer.
