Timber sash windows are valued for their traditional style. Two panels, known as 'sashes,' slide vertically in a frame made of timber. The sashes can be secured in place to ensure weather tightness and security. Their aesthetic appeal makes them a highly desirable choice. We offer our sash windows in traditional cords & weights or a modern spiral balance method of operation, with traditional or heritage style mouldings and bars that are perfect for replacement or conservation areas.
