UPVC Sash Windows

UPVC is an incredible material that allows us to mimic the style and look of timber sash windows at a significantly cheaper price. Our stunning UPVC sash windows can be fitted into a variety of homes and commercial buildings and are some of our most popular products. Whether you would like to retain the period style of your home, purchase cheaper windows or mimic timer, our UPVC sash windows can do all that and more!  

Timber Framed Sash Windows

Timber is one of the most widely-used building materials and it isn’t hard to see why! Timber has been used for hundreds of years thanks to its durability, multiple uses and pleasing appearance. At Sash Windows London Ltd, we sell a variety of timber sash windows that are made to be extremely long-lasting and are protected against rot, decay and weathering. So, when you purchase timber framed sash windows from Sash Windows London Ltd, you can be sure you’re getting the very best.  

Box Sash Windows

Box sash windows are made to mimic, as closely as possible, the windows in existing properties. Box sash windows are ideal for heritage properties, where the traditional window style must be retained. If you purchase our box sash windows, we can guarantee that you won’t be able to tell the traditional windows have been replaced – that’s how close the style is mimicked!
