Our vertical sliders boast authentic period designs that benefit from contemporary manufacturing methods

Sliding sash windows are a timeless classic when it comes to windows, being a staple of period properties whilst still being widely used in contemporary properties, too. If your home still has its original timber sash windows, you’ll have no doubt noticed that draughts, heat loss and rattling frames are a major issue. Not so, our modern uPVC alternatives.


At SRN Home Improvements, our uPVC vertical sliding windows retain all the natural character and aesthetic appeal of their timber counterparts whilst side-stepping all the pitfalls. The tough, secure, weather resistant and rot resistant uPVC frames are available in a variety of authentic woodgrain finishes that seamlessly mimic the real thing. They even retain the classic sash window horns that are such a prominent feature of this timeless design.


All in all, our uPVC sliding sash windows are a perfect choice for properties both old and new. They can even be installed in conservation areas where strict rules apply when it comes to replacing your windows. Perfect!

Delighted by the quality

I got my windows replaced by SRN and am delighted with the quality. There has been an immediate improvement in the warmth inside the house and the anthracite grey colour on the outside looks great. The fitters did an excellent job and tidied up after themselves. Highly recommended
