THE EAST ANGLIAN PROBLEM. THE ENVISAGE ANSWER.
If you live in an older home across East Anglia — a farmhouse, a Victorian terrace, a 1930s semi or a village cottage — you’ll know the feeling. The windows look beautiful from the kerb — but inside, the curtains move on a still day. The hallway is colder than it should be. You can hear every car on the lane. And the frames need painting again.
Envisage Flush windows were designed to fix every one of those problems while keeping the look you fell in love with. The slender frames, the flush-fit opening lights, the period-correct hardware — all present. Behind them, a high-performance multi-chamber profile, U-values as low as 1.2 W/m²K, A+ rated glass and a robust shootbolt locking system. Heritage on the outside. Modern on the inside.
And because they’re uPVC, you’ll never repaint them again.
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.

Don’t underestimate how much of an impact the colour, glazing and hardware you choose will have on the overall window design. Scrutinise every available option before you make any final decision so that your new windows don’t disappoint.
Your home deserves a smart coloured finish...
Several of our coloured finishes evoke memories of the colours painted onto timber flush casement windows. Our colour palette is inclusive of dozens of shades, wood effects and textures. Amber also offers you the option of having a dual-coloured window if you feel that contrasting colours on either side of the window frame will be most beneficial. Envisage has an elegance all of its own and the colours contribute to that.
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.
Envisage windows need to be smartly furnished...
When finalising your new Envisage windows, your window consultant will introduce you to our hardware range. It includes a very extensive choice of handles and hinges, all of which will escalate the attractiveness of the design and help to make the window fully functional. It is impossible to make any wrong decisions as the hardware specifically caters for Envisage.

Will Envisage Flush windows look right on a period property?
Yes — Envisage was designed specifically to replicate the slender lines and flush-fitting opening lights of original timber casement windows. Popular period finishes including Anthracite Grey, Chartwell Green, Cream and Golden Oak woodgrain are all available, and the hardware mirrors traditional door furniture closely. Across Norfolk, Suffolk and Cambridgeshire we've installed them on Victorian terraces, 1930s semis, conservation-area cottages and modern new-builds.
Will they really stop the draughts?
They will. Envisage Flush windows use a high-performance multi-chamber uPVC profile with A+ rated glass, warm-edge spacer bars and weather seals on every opening edge, achieving U-values as low as 1.2 W/m²K. Most Amber customers feel the difference from the very first winter — fewer cold spots, less wind noise and noticeably warmer rooms.
Are they suitable for conservation areas?
In most cases, yes — but conservation-area rules vary by parish. Because Envisage replicates the appearance of traditional timber casements so closely, it's often accepted where standard uPVC profiles aren't. Our team will check your local restrictions during your free survey and guide you through any planning steps if needed.
How long do Envisage Flush windows last, and what's covered?
Every Envisage installation from Amber Home Improvements comes with a 20-year guarantee on parts and labour. The uPVC frame is colour-fast, the seals are weather-tested, and the locking system is fully maintained — and unlike timber, you'll never need to repaint or re-stain them.
