Application

Suitable for commercial, public, heritage, listed building, historic, museums, galleries, offices, universities, residential, schools, colleges, atriums and domestic buildings.

Description

A neat 40mm wide box bar design, ThermGard provides a cost-effective alternative to more expensive sloped curtain walling systems without sacrificing aesthetics. Various slim-line box rafters are available to suit small or large spans. Alternatively the carrier rail may be mounted on top of continuous timber rafters – see our ThermGard-R glazing bars. A continuous screw on pressure plate with gaskets provides outstanding glass retention and a choice of decorative external covers are available to provide either contemporary glass roof appearance or a more traditional heritage style for roof lanterns and typical patent glazing on period buildings.
