Envisage Flush Casement Windows are a modern-day reinvention of the timeless traditional timber flush casement window…

If you know your window designs and Envisage looks familiar to you, it’s probably because it has a distinct likeness to a traditional timber flush casement window.

An Envisage window has the trademark slender lines of an original flush casement window, and the opening lights do not stand proud of the frame, as was traditionally the case when a carpenter would craft an authentic flush casement. Envisage also comes in an array of period finishes and the hardware used couldn’t be more faithful to historic door furniture.

Although a like-for-like window replacement in terms of its appearance, Envisage easily exceeds a traditional timber flush casement for security and performance.

Obviously suited to period townhouses, listed buildings etc., Envisage is also a fine window solution if your new-build home could do with some rustic charm.

The performance of Envisage relies on its glazing...

Amber exploits the very best glazing technology to make our performance glasses as thermally efficient as we can. The U-values provided by an Envisage window can be as low as 1.2W/m2K and we also insert an inert glass into the sealed unit, as well as place a warm-edge spacer bar inside to construct a thermal barrier between the inside and outside. You can anticipate a much more comfortable home with the right glazing solution.
