The system’s large rabbet depth (30 mm overlap) makes sheet fastening easier, and prevents glazing failures due to wind and snow loads or thermal expansion.
For humidity conditions, the Base Profile (No. 307) is designed with drainage channels to collect condensation droplets from the interior surface of the Polycarbonate sheets. Profile No. 310 provides support against the purlin, perpendicular to the direction of the sheet ribs, and channels the condensation droplets towards the rafters and the lower channels of Profile No. 307. To Ensure the dropper flow of the droplets from Profile No. 310 to Profile No. 307, two 90º cuts should be made.
Profile No. 308 is designed to cover the screw attachment area
and is easily installed using a rubber mallet.
The Edge Profile (No. 311 – 314) provides a ventilation gap.
Drainage holes should be drilled.
