How To
- Determine total fastener length needed (insulation + membrane + minimum embedment).
-
Using a screw gun with a #3 Phillips bit, position the fastener perpendicular to the roof surface.
-
Drive until a slight depression appears around the pressure plate or insulation surface, without overdriving.
-
Ensure the plate does not spin, and that the fastener is snug but not over-torqued.
-
On rigid cover boards, avoid stripping the deck by controlling speed and torque.
-
Conduct pull tests in representative areas to confirm suitability and anchorage.
