Metal Pin Screw Fixings (metal pin, plastic body) come in a choice of 5 lengths, allowing them to be used on a variety of thicknesses of insulation. The metal mechanical fixing is made from a metal screw with plastic bodies, meaning that they reduce thermal bridging within the system. The metallic rods are screwed in to give the system stability while reducing the impact on the system when fixing it in place.
These mechanical fixings have an 8mm-wide metal core. The lengths of fixings available are:
115mm (200 fixings per box)
135mm (200 fixings per box)
155mm (200 fixings per box)
175mm (200 fixings per box)
195mm (200 fixings per box)
The Metal Pin Screw Fixings are used to fix the insulation boards to the substrates. With a metal rod and plastic body, they keep thermal bridging down to a minimum, meaning that the system maintains its insulating qualities.
These mechanical fixings are suitable for concrete, brick and other blockwork. If in doubt about the suitability of the substrate, it is recommended a pull test is carried out to ensure it is strong enough to support an EWI system.
