Why mock sash windows?

  • Hugely appealing traditional style
  • Ideal for those worried about security
  • Easier to use than standard sashes
  • Easy maintenance
  • Durable and high performance

Authentic uPVC mock sash windows in Wolverhampton, Birmingham & West Midlands

Mock sash windows look as if they open like vertical sliding sashes. Instead, the windows open out like casement windows, which are far easier to maintain and use. Usually, the larger bottom glass sashes are completely fixed, with the top light having the opening function. This dummy sash on the bottom fixed pane means you can’t tell which windows open and which don’t – a factor that was far more common in historic times, and which can therefore give any modern home a touch of heritage style.

Our mock sash windows are designed to specifically imitate traditional sashes, with a ‘run-through’ sash horn in the frames. You can even choose ‘astragal’ or Georgian bars to give your new windows an authentic Georgian or Edwardian style.

Windows that don’t compromise

Despite their superb style, our mock sash windows offer impressive performance benefits for your home too, particularly when installed by our expert window fitters. They are ideal for anyone concerned about the safety of standard sliding sashes (that leave larger openings). They are also easier to use, which is great news for the whole family.

Living spaces will be more comfortable as well, thanks to the reduction of cold spots and draughts. Our mock sash windows are effective in keeping the heat inside your home, making for cosy spaces even in the height of winter.
