Extreme UPVC Sash Windows
The sliding sash window dates back to the 16th century, and its vertical-opening design is still popular today. Made with two sashes, one set slightly in front of the other, it slides up and down smoothly, making it ideal for period properties. Our Extreme sash windows maintains a similar design to what has been loved through the ages.
Our Extreme sliding sash windows come with energy-efficient glass as standard, and they’re built to last well beyond the warranty. When placing your order, just let us know if you’d like double or triple glazing for added security and comfort.

White is probably the first colour you think of with sliding sash windows, but Yorkshire Windows offers a range of other options too. Our Extreme finishes are made to showcase the quality craftsmanship behind these windows and are easy to keep looking good.
