Available in Ovolo or Bevelled suites with a range of colours to suit any property, our frames are manufactured using Spectus Elite 70 and high quality hardware, to ensure our customers can install our products with confidence.

Vertical Slider

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.

Flush Sash Windows

The Spectus flush sash windows mimic the traditional appearance of period properties, whilst offering superb energy efficiency. We offer two options – welded frame and sash or a fully mechanically jointed option. Flush sash windows are available with traditional monkey tail handles and dummy stays to complete the heritage look.
