75mm Rockwool SP60 Firestop Cavity Slab

The 75mm Rockwool SP60 Firestop Cavity Slab features exceptional lateral compression properties that create a secure, tight seal between structural elements. This fire-stopping system combines the SP FireStop Slab with SP FireStop fixing brackets to deliver a straightforward installation process that requires minimal on-site preparation. The medium-density 75mm ROCKWOOL fire slab incorporates dual-sided foil facing with integrated cutting guides for accurate placement. Engineered to block smoke infiltration and deliver up to 2 hours of fire resistance, this system achieves outstanding fire protection ratings. Movement tolerance of +/- 3% ensures structural stability, whilst its superior acoustic performance significantly suppresses sound transmission across wall and floor cavities.

1. Versatility: Suitable for a wide range of applications, including masonry wall constructions, curtain walling systems, and large cavity voids.
2. Ease of Cutting: 75mm ROCKWOOL SP FireStop Slabs are designed for on-site cutting with a sharp knife or saw and a straight edge.
3. Flexible Installation: The SP Firestop 60 & 120 can be installed horizontally or vertically in cavity widths of up to 400mm.
