Frequently asked questions about this product

What should I use to fix the brackets to the substrate?

The fixing brackets should be mechanically fixed in to the edge of the concrete floor slab or in to blockwork. A minimum 50mm masonry screw should be used.

Does ARC Fire Stop Slab need a compression fit?

A 5mm compression fit is required. When cutting on-site, it is important to ensure the cut size is suitable for the as-built cavity, as no gaps can remain between the barrier and the internal or external leaf.
