Fixing Insulated Panels

Purpose-designed high thread-type fasteners are required to spread upwards loads and maintain the weather seal between the metal skin and the washer. Through fixings for roof panels may be rib fixed or located on a mini-rib within the trough, and should be set snugly to achieve a weatherproof seal without distorting the rib profile. Care must be taken not to over-drive the fasteners as this can cause damage to the G300 outer skin of the panel which can result in water ingress issues

Insulated roof panels with trapezoidal ribs are through-fixed with a load spreading washer on the rib and require lap fixing and sealing at the side laps to the manufacturer’s recommendations.
