Oak Envisage Flush Windows


Our Envisage range is a perfect modern recreation of the traditional timber flush casement window, only we don’t use wood!

If you have a firm knowledge of window designs, an Envisage window will look familiar to you. You will recognise its similarity to a traditional flush casement window due to the woodgrain effect and period hardware attached to the inside. This will make it all the more surprising to you when we reveal that it is manufactured from a UPVC frame, rather than a wooden one.

Oak Envisage Flush Windows

The residents in this house were astounded when they discovered that, and very soon afterwards asked for Envisage windows to be fitted in place of their existing wooden windows. Finished in Golden Oak, they’re a great match.

Providing a very varied mix of openings, each window comes with historically accurate hardware, including monkeytail handles. Each piece of hardware has been modelled on traditional flush casement window furniture and we hope that will immediately become evident when you see them for the first time.

Oak Envisage Flush Windows

The family members are often found gazing at the new windows, just like they do at that extraordinary garden they have. We have been equally as meticulous creating this luxury window suite as the gardeners have when preparing that pretty lawn outside. Envisage has put the flush casement window back in the spotlight.
