Perfect for colder climates or projects targeting passive house standards, these windows offer top thermal insulation and low-maintenance durability. When comfort, sustainability, and standout design all matter, timber-aluminium is the clear choice.
Working closely with architects, builders, and homeowners, we’ve delivered systems that combine thermal efficiency, modern aesthetics, and long-term durability—across private residences, sustainable developments, and architect-led designs.
The renovation project was successfully completed on schedule, surpassing initial insulation and energy efficiency goals by an impressive 70% and delivering a sleek, contemporary finish.
