HOW A THERMAL JOINERY FRAME WORKS
The below close up of the joinery gives you a visual of thepolyamide 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.
