90mm Rockwool SP120 Cavity FireStop Slab (Pack-4)

90mm Rockwool SP60 Cavity FireStop Slab (Pack-4)

Closing the Gap.

Fire compartmentation forms an essential part of any fire prevention strategy, providing resistance against fire spread. The ROCKWOOL Insulation SP FireStop Slab has been specifically designed as part of an effective fire stopping insulation system to form cavity fire stops and accommodate an element of movement encountered within buildings.

The 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 of 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 90mm insulation slab 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.

Key Facts

Multiple use - SP FireStop System including the ROCKWOOL SP Firestop Slabs is suitable for a wide variety of purposes including within masonry constructions, curtain walling systems and large cavity voids.

Easy to cut - ROCKWOOL SP FireStop Slabs are designed for cutting on site with a sharp knife or saw and a straight edge. 

Flexible - the SP FireStop System may be installed horizontally or vertically and is suitable for cavity widths between 50mm and 600mm. SP FireStop can also be used horizontally in cavity widths up to 1000mm. 

Up to 2 hours fire resistance – offering significant protection including the passage of smoke.

Easy to install – the dry fit system saves time and resource on site. For easy compression fitting and to accommodate the fixing pattern, cutting should be along the 1000mm length. The SP Fixing Brackets are then re-profiled by hand and cut as necessary to allow at least 75% penetration of the fire stop material.

SP FireStop can also be used horizontally in cavity widths up to 1000mm. Please contact Insulationbee Technical Solutions for fire resistance ratings in voids over 600mm. 

Acoustic performance

ROCKWOOL products have excellent acoustic properties and can significantly reduce the levels of airborne sound transmission through wall and floor cavities. 

Accreditations 

SP FireStop System has been tested and assessed to BS 476: Part 20. BS EN 1366-4: 2006 and classified to BS EN 13501-2. / Third party approved with LPCB – certificate no. 022b. / Authorised for use in LUL surface and sub-surface premises (LUL Ref: 2244).

Installation

Fixing within cladding & curtain walling systems

1. Cut the ROCKWOOL SP Firestop Slab to suit the *cavity size, allowing for additional compression of up to 10mm.

2. The ROCKWOOL SP60 or SP120 Firestop Slab is impaled onto the SP Fixing Brackets at the rate of 2 per 1000mm length, fixed at 500mm ±10mm centres as shown in Figure 4. The SP Fixing Brackets should be placed 250mm ±10mm in from each end of the ROCKWOOL SP Firestop Slab.

3. The product should then be fitted securely into the void and tightly butted to the adjacent ROCKWOOL SP Firestop Slab.

4. Once the ROCKWOOL SP Firestop Slab has been accurately fitted, the SP Fixing Brackets must then be fitted to the edge of the concrete floor slab with metal fixings suitable for masonry. 

Fixing into masonry wall cavities

5. Cut the ROCKWOOL SP Firestop Slab to suit the *cavity size ensuring a tight fit.

6. After suitably re-profiling the SP Fixing Brackets they can be built into the bed joints of the internal leaf at 500mm ±10mm centres. Alternatively the SP Fixing Brackets may be re-profiled by hand into an ‘L’ shape and mechanically fixed to the face of the inner leaf.

7. The ROCKWOOL SP Firestop Slab is then impaled onto the SP Fixing Bracket after the next lift of inner leaf masonry.

8. Work on both leaves can then be continued and must include either a vertical damp proof course (vertical installation) or a cavity tray (horizontal installation) installed over the SP Firestop Slab as shown in Figure 5.
