SP FireStop System®
The ROCKWOOL SP FireStop System comprises of both the SP FireStop Slab, SP Firestop Plus Slab and SP FireStop fixing brackets. The SP slabs incorporate a foil facing to both sides which helpfully includes cutting lines to support accurate installation.
Whilst resisting the passage of smoke, the SP FireStop System can achieve a fire resistance rating of up to 2 hours in voids of up to 600mm.* In certain applications the system can accomodate movement of +/- 3%. ROCKWOOL SP Firestop system can also help to reduce the levels of sound transmission through wall and floor cavities.
*subject to application
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
Authorised for use in LUL surface and sub-surface premises (LUL Ref: 2244)
Third Party approved with Certifire: CF5836
This information is a summary of the products performance and will vary dependent on the application. Please refer to the product datasheet for full details.
- Easy to cut - ROCKWOOL SP FireStop Slabs are designed for cutting on site with a sharp knife or saw and a straight edge.
- Versatile - the SPFireStop System may be installed horizontally or vertically. It is suitable for cavity widths between 50mm and 600mm*. SP FireStop can also be used horizontally in cavity widths up to 1000mm. Please contact ROCKWOOL Technical Solutions for fire resistance ratings in voids over 600mm.
- Up to 2 hours fire resistance* - offering protection including restricting 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.
The SP Firestop system should be installed in accordance with the guidance noted in the Technical Data sheet and brackets should be mechanically fixed using fixings suitable for the substrate.
In line with evolving construction methods, the SP FireStop System has been successfully tested in conjunction with a Masonry Support System where the system penetrated the SP Firestop.
