Insulated Plasterboard Fixings
Staifix Insofast ISF 18A
Anchors for drywall and insulated plasterboard
The Staifix Insofast ISF 18A anchor secures drywall and insulated plasterboard panels to walls. This one piece fire-proof metal fastener has a self-tapping helical shank with work-hardened blades that cut into a wide range of masonry and timber substrates.
Staifix Insofast 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).
Critically, these high integrity mechanical fixings ensure stability of the boards in the event of a fire to prevent escape routes from becoming blocked.
Heat loss through cold bridging is minimised thanks to a thermally-efficient spiral shaft; the cross-sectional area is just 25% that of a solid shaft of equal diameter.
The fixings are driven-in by the adaptor, powered by a standard light SDS hammer drill (1-2kg with 2-3 joules). Alternatively, these fixings can be installed using a series of light blows from a rubber/plastic mallet.
The anchor drives directly into aircrete blocks and softwood timber. A 5mm pilot hole is recommended for brick, concrete block and hardwood. A 6mm pilot hole is required for structural concrete and engineered brick.
The embedment depths stated do not include any surface coverings, such as plaster, over the host material. Longer fixings may be required to achieve the necessary embedment in the backing structure.
Specifying modern brick-faced soffits just got easier, with the publication of Ancon’s new 16-page Nexus brochure.
Ancon will further expand its wide product range with new product launches at the UK’s largest event for specifiers in the built environment, Ecobuild 2017.
