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 come in a varitey of designs – box sash windows, wooden sash windows and double glazed sash windows – and all 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.
Sash Windows – Designs
All our windows are made-to-measure to fit your existing aperture. If required, we can match glazing bar patterns and styles.
We offer traditional brass or chrome handles and catches as part of the package.

Traditional sash windows are available with brass or chrome fittings
