The RW5 are the best quality resin bonded Slabs designed for full fill cavity insulation applications and is an effective cavity wall insulation material. These slabs feature great applications in a wide range of thermal, acoustic and fire insulation requirements in buildings and industries. These slabs are ideal for many applications including thermal insulation for cavity walls.

The ProRox SL 960 100mm have good thermal and fire resistance properties and therefore reduces the risk of condensation in cavity wall constructions. The use of these slabs also prevents the transmission of water from the outer leaf of the construction to the inner leaf. The built-in structure of the fibers used in Rockwool Slabs also makes them the ideal to be used as a sound absorber, with high coefficients over a wide frequency range.
