The window frame and sash of this type are covered with aluminium cladding from the external side, which may be in the same colour as the window or in another colour that suits the building’s elevation. It is a perfect combination of the modernity and durability of metal with the aesthetic and cosy atmosphere provided by wood. This window type is ideal for modern architectural buildings. Another advantage comes with higher thermal insulation, improved weather resistance and the fact that these windows are easy to clean and maintain. Aluminium cladded windows are the new generation of window construction. Their durability and ease of operation makes them a popular choice in housing, offices, public buildings and in modern architecture.
