Double Glazed uPVC Sash Windows

uPVC sash windows have become a popular choice due to their easy maintenance and durability. These windows offer energy efficiency, reducing heat loss and improving insulation. The history of sash windows dates back to 17th-century England. Modern uPVC sash windows provide options for enhanced ventilation and improved air circulation. Unlike timber sash windows, uPVC sash windows traditionally slide one pane of glass over another using a pulley system. With different styles available, such as Georgian bars and various glazing options, uPVC sash windows offer both functionality and aesthetic appeal.
