The 453 Series Thermal Break Window System provides the ultimate in energy efficient aluminium framing.

By utilising the well-proven practice of bridging and strut insertion, the 453 Series ensures improved performance over standard one piece aluminium framing and achieves superior "whole of window" U-value results when combined with a Low E coated IGU.

Features

Why Thermal Break

Thermal-performance windows are fabricated from extrusions inserted with rigid, polyamide struts to bridge two separate aluminium profiles. These struts effectively isolate and restrict the temperature transfer from the outside to the inside and visa versa.

Thermal imaging demonstrates how a normal aluminium frame with an exterior temperature of -14.7°C results in an internal temperature transfer of approx. -1.3°C (see Figure 2.1). In contrast, Figure 2.2 shows the effectiveness of the 453 Series strut insert in preventing the conduction of the external cold (-14.6°C) through to the internal frame component which remains at a static temperature of around 7°C.
