Description

A range of overhead glazing bars and roof windows cater for a variety of commercial and residential applications. Bars with a drainage system and condensation collection system are available.

A structurally glazed Thermal Heart roof window for maximum thermal efficiency is available in both opening and fixed options. This is supplied with a 24mm IGU, Argon gas fill and low-e inner pane. A large range of sizes is available, including large expanses for the fixed Thermal Heart window through the use of an added mullion.
