Vertical Sliding Sash Window

Sash windows offer a traditional looking window without the maintenance. Advanced technology comes together with time-tested design to create the perfect replica of period timber windows.

Our vertical sliding sash windows combine the benefits of high performance materials with period character. We achieve an authentic look with ovolo finishing, wood grain colours and Georgian bars. We can even create sash windows with arched tops!

The graceful style of sash windows is difficult to beat. But timber sashes, particularly old ones, are troublesome and require regular maintenance. The Spectus Vertical Slider has been designed to provide the authentic, period appearance without the drawbacks. It’s so good that planning departments have accepted it – even in conservation areas.

We offer optional Georgian bars and sash horns to match original designs and a consistent period look with ovolo detailing to the frame, sash, beads and cills.

These are beautiful, sliding-sash windows that are easy to maintain, insulating and secure. What’s more they can achieve a Band ‘A’ Window Energy Rating. Grace and elegance are now combined with performance and all the benefits of 21st century materials and technology.
