Insulation Attachment
Icopal Thermazone PIR insulation boards should be attached at the minimum rate of 11 tubes & fasteners per 1.2 m x 2.4 m board (unless otherwise specified and approved). An increased density may be recommended depending on project location, height and exposure etc.
Membrane Attachment
For every mechanically fastened roof, a wind uplift calculation and fastener specification will be required prior to installation of the Icopal roof waterproofing membrane. All calculations are conducted in accordance with BS 6399 or BS EN 1991 parts 1-4, as appropriate.
Fastener Application
No pre-drilling is necessary for timber and steel decks.
Simply insert the fastener through the tubular washer and install with a standard clutch drive electric screw gun (0 – 2500 rpm). Optimum fastener performance is achieved when fastener is installed perpendicular to the deck and into the top flutes of a steel deck.
The TX-25 recess provides excellent drivability and the drill-point design cuts a hole in the steel deck maintaining contact between the deck and the minor diameter of the fastener, increasing back-out resistance.
