Thermally Broken

Thermally broken systems are used to create insulated windows and doors, with high levels of thermal performance.

If your window or door is going to be separating two different climates, the inside and the outside of a home for instance, you must use a window or door system that is thermally broken.

A thermal break means that there is a non-conductive material separating the internal metal frame with the external. This is imperative for external windows and doors. Steel and architectural metals conduct heat very easily. If you do not have a thermal break within the steel framing (as is the case with lots of traditional steel windows and doors) the internal side of the metal frame will be the same temperature as the external frame. In winter or in colder climates this will cause the internal face of your metal window frame to become very cold, bringing in cold drafts from outside and creating a prime location for condensation and frost to form.

Many traditional steel window systems do not have a thermal break within the framing. Thermal break technology is relatively new and innovative, allowing us to create ultra slim steel framing, with a full thermal break, without decreasing the inherent strength of  the steel construction.

We offer a wide range of metal windows and doors, all with a full two part thermal break throughout the framing for enhanced levels of thermal insulation.

CWS-B50 Slim

Steel and bronze windows have been, and still, continue to be the preferred choice for architects due to their graceful aesthetic and design qualities. The CWS-B50 Slim fulfils architectural requirements and provides an elegant and stylish system with a thermally broken bronze frame of 55.5mm deep and a fixed sightline of only 32mm. In addition to impressive acoustic performance and high thermal performance, the system provides high levels of security and weather resistance.
