uPVC-aluminium windows

Although white uPVC windows are still  popular, many customers these days are looking for more flexibility and uPVC-aluminium composite windows are the perfect solution. The powder-coated aluminium cladding on the outside of the uPVC-aluminium window is maintenance-free and available in many colours and surface options, with the current trend being dark grey, stainless steel or metallic colours. The demand for more neutral beige and brown tones in addition to the numerous grey tones for aluminium composite windows is also on the rise.

Further to a wide range of colours and design styles of the UPVC-aluminium windows, we can also offer you technical highlights such as I-tec ventilation. This ventilation can be fitted directly into the uPVC-aluminium window frame of KF 410 or KV 440. You can control how strong the ventilation should be and how often it should be switched on - and this individually for each uPVC-aluminium window, therefore controlling the climate in each room. Further information about I-tec Ventilation can be found under: ventilation for living area.

The triple-glazed uPVC-aluminium windows provide exceptionally high performance, with U-values as low as 0.62 W/(m2K) and noise reduction as high as 47 dB. The more recent KF 520 and new KF 510 also include the patented I-tec Secure locking system, which makes the windows virtually burglary proof.

At Internorm, we manufacture uPVC-aluminium windows to your required sizes, options and individual requirements. You can choose the window size, colour, hardware, handles, security options, design styles, as well as shading and fly screen options.
