uPVC Sliding Sash Windows

Vertical sliders, also known as sliding sash windows, are a classic architectural feature commonly found in older homes, particularly in Victorian and Georgian styles. They consist of two vertically sliding panels, or sashes, that can move up and down within the window frame. Typically, one or both sashes can be opened, allowing for ventilation and airflow.

These windows are often praised for their elegant appearance and versatility. They can be made from various materials such as wood, uPVC (unplasticized polyvinyl chloride), or aluminum, each offering its own set of benefits and aesthetics.

One of the key advantages of vertical sliders is their ability to provide effective ventilation while maintaining the traditional look of a property. By opening both the top and bottom sashes, air can circulate through the room, helping to regulate temperature and improve indoor air quality.

Traditional timber frames require regular maintenance, can be difficult to replace and are often expensive. Our uPVC sliding sash windows offer the classic lines and character of traditional timber frames coupled with the high performance of modern vertical sliding windows. Designed to stand up anything the British weather has without warping or cracking, you will benefit from their beautiful aesthetic, impressive functionality and high performing energy-efficiency. These benefits will last a long time without deterioration or discolouration.
