Vertical sliding sash windows closely replicate the traditional features of a traditional sash window, but with the added benefits that uPVC provides.
Modern uPVC Vertical Sliders are designed and engineered to accommodate everyday life, while at the same time being simple and easy to operate.
The main difference between a modern uPVC sliding sash window (apart from the material) and more traditional timber box sash windows is the means of holding the sashes in position. Instead of weights, pulleys and a cord, a pair of sophisticated spring and spiral balancers are now used in modern siding windows. Their design means that modern sliding windows can carry sash weights of up to 40kg.
