Non-thermal break aluminum awning windows are a type of window that is made from aluminum and does not have a thermal break. A thermal break is a piece of material, typically a low-conductive material like PVC or nylon, that separates the interior and exterior parts of the window frame. This helps to prevent heat transfer between the inside and outside of the window frame, which can help to improve energy efficiency. Awning windows are a type of window that are hinged at the top and open outwards from the bottom, similar to an awning. They are often used in areas where ventilation and natural light are desired, but where space is limited. Non-thermal break aluminum awning windows are typically less expensive than thermal break aluminum awning windows, but they are also less energy-efficient. This is because aluminum is a good conductor of heat, which means that it can allow heat to transfer through the frame and into the building. As a result, non-thermal break aluminum awning windows can contribute to heat loss in the winter and heat gain in the summer. If energy efficiency is a concern, it may be worth considering a different type of window, such as a thermal break aluminum awning window or a vinyl or fiberglass window, which are typically more energy-efficient than non-thermal break aluminum windows.
