A choice of plastic windows with decorative foils is a good decision: excellent insulation parameters, durability and good value for money. Thanks to the wide offer of single-color foil or those imitating the appearance of wooden windows, it is possible to meet the individual wishes of our customers. Schüco decorative foils can be applied both on one side and on both sides of the profile, which allows for a good adjustment of the joinery to the elevation and interior of the building. Structured or smooth decorative foils allow for interesting placement of architectural accents, enabling individual concepts in case of any type of building and any interior and elevation arrangement.
