ROCKWOOL SP FireStop Slab provides a unique lateral compression to facilitate a tight fit between substrates.
As a simple to use, cut and install solution, the ROCKWOOL SP FireStop System comprises both the SP FireStop Slab and SP FireStop fixing brackets. A medium density ROCKWOOL slab, it incorporates a foil facing to both sides which helpfully includes cutting lines to support accurate installation. Whilst resisting the passage of smoke and providing up to 2 hours fire resistance, the SP FireStop System can achieve a fire resistance rating of up to 2 hours in voids of up to 600mm.
Protecting against both movement of +/- 3% and also acoustic loss, this ROCKWOOL product has outstanding acoustic properties, significantly reducing the levels of sound transmission through wall and floor cavities.
