6-35 Aluminum Glazing System
Polygal's 6-35 Glazing System is a large-span clamping system specially
developed for glazing applications using 6-35 mm thick Polycarbonate
structured sheets. Sheets are mounted on the system's load-bearing
elements during construction of transparent and semi-transparent roofing.
The system's large rabbet depth (30 mm overlap) makes sheet fastening
easier, and prevents glazing failures due to wind and snow loads or
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.
