Insofast-18 warm roofing fixings are button-headed nails having engineered Thor Helical shanks to corkscrew into roofing timbers. Insofast flat roof fixings offer a 80% reduction in cold bridging, compared to zinc plated Suretwist fixings, due to a CSA measuring just 9mm2 and due to stainless steel being 4 times less conductive than carbon steel. Additionally stainless insulation fasteners offer maximum protection against the corrosion potential of interstitial condensation.
