EcoGain - windows that help heat your home
Our A-rated EcoGain casement windows represent a truly remarkable progression in window performance and technology.
The EcoGain concept is such an impressive improvement on standard double-glazing because it not only keeps draughts out and more of your heat in, it actually helps add heat to your home. This means you can reduce your heating energy usage, helping to cut down your fuel bills and keeping your house warmer.
Our research and development team have looked at every single element of the window's design and construction, and improved and fine-tuned it to produce a window that is not only energy efficient, but now makes a positive contribution to your home’s heating.
So what makes it different? Our A-rated EcoGain window looks, at first glance, exactly the same as our B-rated EcoRetain casement window, but the amazing difference lies in how it lets in more sunlight and therefore free heat than an EcoRetain window; so much so, that it can more than compensate for any heat that is lost through the window from inside to out.
The result: a window that can actually add to the warmth inside your home.
