Energy Efficient

Our vertical sliding sash windows are designed with security in mind and with some simple upgrade options can achieve the Secured by Design standard.

Low Maintenance

All these windows need is a simple wipe with a soapy cloth – this can be done from insideĀ as each window comes with the function to beĀ tilted inwards.


There is a wide range of window colours and woodgrains to suit your style, with the option to have different colours inside and out.


  • A slim top sliding sash enhances sight lines even when coupled to the bottom sash when closed.
  • The modern lines of the top sash can be traditionalised with the addition of clip-in or run-through horns
  • A deep bottom rail on the bottom sliding sash also contributes to the authentic look. Mechanically joining gives the appearance of a butt joint for a traditional timber feel. An enhanced bottom gasket is also included on the bottom sash for improved weather proofing.
  • The cill is an integral part of the window, particularly for the bay windows where its one piece design helps give the appearance of one complete window when installed.

All windows are available in 18 different colours. They can be in a single colour, or dual colour (different inside and out).
