Staifix Insofast ISF 18A Insulated Plasterboard Fixing

Product catalog summary

Product Overview: The Staifix Insofast ISF 18A is a fire-proof mechanical fixing designed for drywall and insulated plasterboard. It features a helical shaft to minimize heat loss through cold bridging and a countersunk head to prevent tearing and retain filler. This product is part of the Staifix range of helical fixings.

Benefits: The ISF 18A fixings are suitable for all types of insulated drywall boards and can be used with or without 'dot and dab' adhesive. They ensure stability in the event of a fire, preventing escape routes from being blocked. The thermally-efficient spiral shaft reduces heat loss, with a cross-sectional area of just 25% of a solid shaft of equal diameter.

Installation: The fixings are installed using an SDS hammer drill and an adaptor. They can be driven directly into aircrete blocks and softwood timber, while a 5mm pilot hole is recommended for brick, concrete block, and hardwood. A 6mm pilot hole is required for structural concrete and engineering brick.

Product Specification: The fixings are made from zinc-plated AISI 1008 steel or austenitic 304 stainless steel, with a shank cross-sectional area of 9mm². Typical load capacities are 649N for aircrete, 622N for brick, and 681N for softwood. Pull-through capacities are 255N for 9.5mm plasterboard and 340N for 12.5mm plasterboard. Embedment depths vary by material, and available lengths range from 65mm to 145mm.

Usage Recommendations: When used with the 'dot and dab' method, three fixings per panel are required, with each dab measuring 50mm to 75mm wide and approximately 250mm long.
