About Thermotek Windows and Doors

Smart, Sustainable Construction for High-Performance Projects

Thermotek delivers world-class, energy-efficient uPVC window and door systems, purpose-built for Australian conditions. Manufactured locally in Melbourne and engineered with advanced German profiles, our systems combine superior insulation, acoustic performance, and durability with design flexibility for residential and commercial applications.

Fusion-welded uPVC frames, multi-chamber profiles, and precision hardware achieve energy ratings as low as Uw 1.2 (WERS) and bushfire compliance up to BAL 40. Double or triple glazing options with multi-point locking systems provide enhanced comfort, security, and long-term performance.

Whether specifying for a Passive House, sustainable multi-residential development, or a bespoke custom build, Thermotek offers end-to-end project support, local expertise, and a commitment to smart, sustainable construction.
