Key Information

Product Information

The Rockwool SP Firestop Fixing Brackets are a vital component of the Rockwool SP FireStop System—an innovative fire protection solution developed to maintain fire compartmentation and slow the spread of fire within buildings. This system is specifically designed to create effective cavity fire stops and plays a key role in enhancing a building’s passive fire protection.

Designed for Performance and Practicality

The brackets come in two sizes: SP/S (small) for cavity widths up to 100mm and SP/L (large) for cavities up to 400mm. Supplied in packs of 50, they arrive flat-packed in a compact cardboard box and can be easily reshaped by hand to suit the application during installation. This makes them especially convenient for on-site adjustments without the need for specialised tools.

Easy to Shape, Simple to Install

To meet the fire testing requirements and certification of the SP FireStop system, it is essential that these dedicated fixing brackets are used during installation. They are designed to allow at least 75% penetration into the SP FireStop EN slab, which can be trimmed to fit on-site using a sharp knife or insulation saw. Brackets should be mechanically fixed with appropriate fixings depending on the building substrate, as outlined in the product’s technical datasheet.
