Thermal Standard
Double Glazed Windows
Two panes. Argon-filled. Engineered to exceed NCC Section J requirements for modern Australian homes.
Overview
Our double glazed systems combine two panes of high-clarity toughened glass with an argon-filled cavity and warm-edge spacer bars.
The result is a thermal envelope that outperforms standard aluminium by a factor of five, delivering genuine year-round comfort without compromising the minimalist aesthetic Australian architects demand.
