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.
ARC OSCB cavity barriers are designed for installation within cavities where ventilation is required in service use.
Product detailsARC Party Wall DPC enables the closing of an external cavity at either party wall or party floor junctions where building regulations require the use of mineral wool closer for acoustic insulation purposes.
Product detailsARC Eco-Closer closes the cavity around window and door openings in masonry walls, providing up to 60 minutes fire integrity.
Product detailsARC Fire Stop Strip is designed to prevent the passage of smoke and flames through narrow voids in the construction.
