Why use four different window and door systems in one home?

Because each part of a project has different requirements.

For this large-scale coastal home in Rye, the window and door selection needed to balance expansive views and natural light with ventilation, thermal comfort and performance in demanding coastal conditions.

Lift & Slide systems create wide openings across key living areas, Tilt & Turn and Mechanical Awning windows provide controlled ventilation, while Fixed Picture windows frame the coastal outlook.

Rather than making one product work everywhere, it’s about choosing the right solution for each part of the home.

Out with the bulky, inefficient frames. In with high-performance uPVC. ❄️

This retrofit lifted thermal performance, cut the draughts and opened up the view, all in a single day, with no structural changes.

Better seal. Better comfort. Better living. Just in time for winter. Big thanks to Adam and Meryn for sharing their project 🙌

A project taking shape.

With the exterior cladding, windows and doors now coming together, you can start to see the character of this home emerging.

There’s still plenty to do, but each stage brings the design closer to the finished home.

100 days to build. 100 years of life in the frame. And a home built for the people who'll live past 100. 🏡

That's the thinking, and it's why the windows matter.

A house that's meant to last a century needs an envelope that can go the distance, high-performance uPVC, engineered for the airtightness, insulation and comfort a Passivhaus build depends on. Not just for for a decade, but for beyond a century.

Built fast. Built once. Built to outlive us.

Comfort starts with keeping the cold out❄️
For this .building.group project, our high-performance uPVC windows and doors do the quiet work: sealing out draughts, holding insulation in, and keeping airflow where it should be.

It's the kind of performance that helps builders exceed 7-star construction and deliver homes that stay comfortable through a Melbourne winter.

That's the Thermotek difference. 🏡

Built in 100 days. Designed for 100 years. 🏡

In collaboration with Stllhaus , this case study shows what happens when innovative prefabrication meets windows and doors engineered for long-term performance.

Passivhaus construction is known for being hard to scale the airtightness and insulation targets are demanding. Our high-performance uPVC Tilt and Turn and Smart slide systems help Stllhaus hit Passivhaus level building quality in a 100 days of building.

Swipe through the journey, and stay tuned: blower door testing, final styling and the finished result are coming soon.
