Aluminium windows

High-quality and energy-efficient aluminium windows

Windows have to perform a wide range of functions: They create light-filled spaces and provide a view of the outdoors. At the same time they should keep out heat, cold and noise as well as protect against burglary. Whatever their function, windows must be able to be integrated into any building architecture, and that means they require a high degree of flexibility in terms of colour and design. We will show you how you can combine different requirements and what you should pay attention to when choosing your aluminium windows.

Innovative coating technologies for aluminium window profiles

Aluminium windows in RAL colours

Robust, weather- and UV-resistant hwr powder coating maintains the colour intensity of your window frames through the years. Tests have shown that the colour and gloss intensity remains virtually unchanged compared to conventional coating processes, even years after installation. Any colour in the RAL colour palette can be used for heroal aluminium windows. In addition, you can choose between different degrees of gloss from grainy to matt to glossy. The surface of your window frames is not only sustainable and environmentally friendly, but also easy to maintain. Take a look at a small selection of the available colours.

Aluminium windows with a concrete, rust or wood look

heroal SD coating technology provides a broad range of design possibilities for the surface of aluminium window frames. The aluminium profiles are sealed in PE foil in a vacuum process and then the design is burned in using heat exposure. This makes it possible to give the surface of your aluminium windows an attractive wood, concrete or rust look. This surface coating stands out for its high durability (equivalent to hwr powder coating) and its refined look. Take a look at some design options for heroal aluminium windows.
