The German Window Company brings you traditional hardwood box sash windows as well as double glazed sash windows at affordable prices.

Our sash windows principally come in two main designs, either traditionally hung on cords and weights, this method gives long lasting reliability. As an alternative we can supply the latest improved design of spiral springs. This system allows a smaller frame size than the traditional box sash window.

With the and advanced manufacturing processes of our state-of-the-art European factories, we are able to produce precision-made timber and replica material windows of extremely high quality at prices that have not previously been seen in the UK.
