Description

A one piece metal fastener with a dish profiled head for mechanically securing drywall and insulated plasterboard panels to walls. Prevents dot and dab plasterboard from falling on persons escaping a blazing building, or on persons entering a blazing building for rescue purposes.

The fire-proof metal fastener has a self-tapping helical shank with work hardened blades able to cut into a wide range of masonry. Hammer in with a rubber mallet or with an SDS adaptor in a light-weight drill set at slow speed on hammer only action.

Benefits

ISF18A fixings are suitable for use with all types of insulated drywall boards. They can be used in conjunction with dot and dab adhesive (3 per board) or in place of it (12 per board), to ensure stability of the boards in the event of a fire.

Cold bridging is minimised thanks to a thermally efficient spiral shaft that has a cross sectional area just 25% of that of a solid shaft of equal diameter. Also by virtue of a fully countersunk head, which indents into the gyproc layer without tearing.

The plasterboard fixing drives directly into Aircrete (Celcon, Thermalite, etc.). Use 5mm pilot hole for fixing in brick, concrete or concrete block.
