ThermGard

Description

Designed to combine the benefits of more costly curtain walling sections with the rapid installation advantage of traditional two-edge support glazing to provide thermal break roof glazing.

System incorporates a ventilated internal box-rafter design to minimise the risk of condensation, continuous pressure plates and snap on covers to provide invisible fixings and a low profile appearance. An optional period style aluminium box-rafter and capping is available for heritage buildings.
