More about us

Easy to use and low maintenance - Vertical Sliding Sash Windows for homes in Buckingham

Our vertical sliding sash windows have -been designed to be as user-friendly as possible. Modern spiral balance mechanisms allow you to open the sash as far as you want, and the window will stay in that position. The safety restrictors prevent the sashes from opening too far, making them safe around young children.
Unlike traditional timber frames that will require regular maintenance such as sanding, painting, and preserving, our uPVC vertical sliders can simply be washed with soapy water and dried with a clean cloth, to keep them looking their best for years. Regularly cleaning the drainage channels and a drop of beeswax polish on the sliding mechanism will ensure they work like new for many years too.
Get in touch with us to find out which vertical sliders are right for your home.
