Rockwool HP Partial Fill Cavity Slabs comprise a robust outer surface (designed to withstand on-site rigours) engineered to a resilient inner face (designed to absorb
irregularities of the inner leaf).
The robust surface maintains a more clearly defined cavity whilst the resilient inner surface eliminates ‘stand off’ from the inner leaf, maximising thermal performance.
Due to the nature of the material, the
slabs will knit together when tightly butt jointed. Extraneous heat loss caused by gaps is eliminated, ensuring a thermally efficient system.
