A semi-rigid partial fill insulation solution for masonry and framed cavity wall construction, ROCKWOOL High Performance Partial Fill Cavity Slab is designed to withstand typical conditions on-site and absorb any irregularities on the inner leaf. Made of renewable stone wool fibres, HP Partial Fill slabs further maximise energy efficiency by knitting together when tightly jointed to eliminate gaps

ROCKWOOL HP partial fill cavity slab can be used in any exposure zone where a residual cavity width of 50mm or greater is maintained. However, the use of the product does not preclude the need to apply any external render coat or other suitable finish in severe exposure zones where such application would be normal practice.
