Thermal Strut® Windows

System Description

2” face x 2” to 4 1/2” back sections of extruded aluminum with the exterior face separated from the interior face with an integral polyamide thermal break. Screw spline joinery with mitered joints. Pressure equalized rain screen design with each glazing unit compartmentalized and drained and vented to the exterior with weep holes. Exterior glazed with extruded aluminum stops.


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