Sash windows

The German Window Company brings you traditional hardwood sash windows at affordable prices.

This means that you can now retain the character of your house without compromising its value by fitting uPVC or aluminium windows.

Our sash windows are traditionally hung on cords and weights, which give you long-lasting reliability - unlike unreliable spiral springs. 

With the economies of scale and advanced manufacturing processes of our state-of-the-art German factory, we are able to produce precision-made hardwood windows of extremely high quality at prices that have not previously been seen in the UK.
