INSOFAST - A new insulation fastener range with a twist

Twistfix launch an innovative range of insulation fasteners, featuring a unique corkscrew design to provide easier and more secure fixing of insulation. INSOFAST fixings are approved by leading insulation manuf­ac­turers and suppliers for a wide range of applications .

The range includes a thermal break fastener for external wall insulation systems, together with dedicated fire-resistant fasteners for fastening fireproof insulation slabs to soffits and button head fixings for fixing composite insulation boards to flat roof decks

These versatile insulation fasteners are suitable for a wide variety of substrates when driven home using a conventional hammer or a special SDS hammer drill adapter.­  Hammer in directly or use pilot hole when fixing into harder substrates such as brick and concrete. They can also be fixed directly into aircrete blocks without pre-drilling and into timber.

The patented fasteners have a thermally-efficient spiral shaft, 75% smaller in cross sectional area than conventional shafts of equivalent diameter, providing reduced cold bridging and minimised disturbance to the materials being used.
