ThermGard
Contemporary thermal break roof glazing system to suit glass and polycarbonates for heated or unheated spaces. Heritage design available.
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.
