Thermal Strut® Skylight

System Description

The CGS Skylight System incorporates a rafter purlin design which allows the drainage of any incidental moisture to "dump" into the rafter and out at the sill. The system is thermally broken at the pressure plate at the top edge of the sealed unit and is pressure equalized to allow the system to perform as a "Rain Screen".


Aluminum alloy 6063 T5 or T6 from commercial grade aluminum that may contain 25% recycled material. Extruded PVC thermal break separating the exterior and interior extrusions providing a single strength section of high performing thermal and structural qualities.
