InSkew is a high performance, stainless steel, self-tapping helical fixing for secure timber counter battens, through insulation, in pitched warm roof constructions. Designed specifically for use in warm roof construction, high performance InSkews are hammer or power driven through battens, counter battens and insulation, without affecting its thermal properties, and into the rafters. Their self-tapping design produces excellent holding power in both tension and compression and they are structurally more reliable, due to their helical profile, and more economical than traditional nails as far fewer are required. Since the publication of Building Regulations Part L, 2006, the new u values for pitched warm roofs, where the insulation is above the rafter, is 0.18 “ 0.20 W/m2K. Warm roofs, used to maximise living space and constructed using InSkews, have been shown to comply with these latest Part L Building Regulations. Material: austenitic stanless steel grade 304. Features Compliance with Building Regulations “ Part L. Reduces heat loss and retained heat gain. Lagging of pipes and tanks eliminated. Reduces running costs. No cold bridging. Protection against damp and corrosion. Roof tile ventilation no longer required. Produces a Room-in-a-Roof space.
