Internorm uPVC-aluminium windows

Although white uPVC windowsare 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.
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.
