How does thermal joinery work?

This close up of the joinery gives you a visual of the polyamide strip, or thermal break, which reduces outside temperatures from being transferred through the frame, impacting internal temperatures.

Why thermal frames make a difference

These models show a non-thermal vs thermal frame. The outside temperatures on each model are the same (-1C), but there is a noticeable difference in the inside frame temperatures. Thermal frames reduce the heating required to create a warm, cosy, comfortable home.

We deliver exactly what we promise.
