ROCKWOOL® High Performance Partial Fill Cavity Slabs are a robust and durable solution for the thermal insulation of external masonry cavity walls. High Performance Partial Fill slabs further maximize energy efficiency by knitting together when tightly jointed in order to eliminate performance sapping gaps.
