Self-drilling insulation screws fix rigid board and mineral wool directly to light gauge steel purlins and roof decking with no pre-drilling — the bugle head pulls the board down without crushing it. Available in Torx T25 and Phillips PH2 drives, in lengths from 60mm to 300mm, with EvoShield® 500HR coating as standard. Pair with a round or oval stress plate to spread the load on soft or thick insulation.

Sharp point insulation screws drive straight into timber rafters, joists and boards, with a coarse single thread for maximum pull-out in softwood and a 1,000-hour EvoShield® coating for extended service life. Self-drilling versions also handle timber, so one screw can cover a mixed steel-and-timber job.

Galvanised metal insulation anchors fix rigid boards and mineral wool to blockwork, brickwork and concrete through a simple 8mm drilled hole, with a 40mm compression disk holding the insulation firm — A2 stainless versions cover more demanding environments. Concrete insulation screws with a UV-stabilised 25mm nylon head fix insulation systems direct to concrete ceilings and soffits in lengths up to 350mm, and for built-up roofs on concrete decks, heavy duty multi-purpose roofing screws fasten insulation and single ply membrane to steel, timber and concrete alike.

Stress plates, recessed washers and insulation disks stop membrane and insulation pulling over the fastener head on single ply and built-up flat roofs. Choose galvanised round and oval plates for standard work, A2 stainless for corrosive conditions, and polypropylene or capped washers where a thermal break or telescopic fixing is needed.
