Rockwool Fixing Brackets SP/L for 400mm Cavity (50 pack)

Rockwool SP/L Fixing Brackets are required for the installation of Rockwool Firestop SP60 and SP120 slabs. They are designed for cavities up to, and including 400mm wide. These bracket clips that are bent to an L shape. The leg with the angled point is 300mm long; this leg is impaled into the base of the fire stop. These brackets are required to maintain stability in the entire structure assembly whilst maintaining the fire rating of the products used. The SP/S Fixing Brackets should be cut on site as necessary to allow at least 75% penetration of the Firestop.

• To be used in conjunction with steel fixings to maintain structural stability,
• To be used with Rockwool's SP Fire barrier systems,
• Comes in a box of 50 bracket clips.

Uses

• To be used in masonry cavity walls and curtain wall constructions with Rockwool SP60 and SP120 Firestop Slabs.

INSTALLATION

Masonry wall cavities

• Cut the Rockwool SP Firestop Slab to suit the cavity size, ensuring a tight fit.
• 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.
• The Rockwool SP Firestop Slab is then impaled onto the SP Fixing Bracket after the next lift of inner leaf masonry.
• Work on both leaves can then be continued and must include either a vertical damp proof course or a cavity tray, installed over the Rockwool SP Firestop Slab.

NB: For cavity widths of 250mm or more, joints between adjacent lengths of firestops should be sealed on the top surface with aluminium foil tape.

Curtain Walling

• Cut the Rockwool SP Firestop Slab allowing an additional 35mm for compression when fitted.
• The Rockwool SP is impaled onto the SP Fixing Brackets at the rate of 2 per 1000mm length, fixed at 500mm 10mm centres,
• The SP Fixing Brackets should be placed 250mm 10mm in from each end of the Rockwool SP Firestop Slab.
• The product should then be fitted securely into the void, and tightly butted to the adjacent Rockwool SP Firestop Slab.
• Once the Rockwool SP Firestop Slab has been accurately fitted, the SP Fixing Brackets must then be mechanically fixed to the edge of the floor slab with metal fixings suitable for masonry.
