The window with two facets
Dear Builders,
there are windows on which everything is highly promising: the appearance, the materials used and the many special design feature available. Let yourself be fascinated and inspired by the „two facets of a window“. The Aluminium-uPVC window from KNEER-SÜDFENSTER combines the advantages of two different, highly valued materials in one window. The excellent thermal protection characteristics of the uPVC window are perfectly combined with the external, weather-resistant Aluminium shell. The Aluminium powder-coating of the external shell guarantees durability and long-lasting colour, and it is, at the same time, easy to care for, low-maintenance and refreshingly colourful!
