Would you like to replace your old windows while keeping the character of your home? That is exactly what greenEvolution Free, now available at Fensterprofi12, is designed for. This uPVC window by Eko-Okna combines a traditional, slim appearance with insulation values at passive house level. It is the further development of the proven greenEvolution Flex system.
More light thanks to slim profiles
The most striking feature of greenEvolution Free is its very narrow sight line. Frames and mullions are considerably slimmer than on many conventional uPVC windows. This increases the glass area, letting noticeably more daylight into your rooms. Large window fronts look light and elegant, without bulky frames.
Uw 0.77 W/m²K: excellent insulation despite the slim design
With greenEvolution Free, slim profiles do not mean compromising on energy efficiency. The Uw value of 0.77 W/m²K meets the level required for passive houses. For you, this means lower heat loss, reduced heating costs and pleasantly warm surfaces at the window, even in winter.
Up to 48 mm glazing for thermal and sound insulation
The profiles accommodate glazing units up to 48 mm thick. This allows modern triple glazing and special acoustic glass to be fitted. If you live on a busy road, this brings peace and quiet into your home.
French casement windows: symmetrical look without a centre mullion
The French casement version is particularly popular for renovating period buildings. There is no fixed mullion between the sashes. The handle sits in the centre, the view remains symmetrical, and when both sashes are open, you have the full window width available. This preserves the classic look of the façade.
Timeless design in many colours
The slim profiles suit a historic façade just as well as a minimalist new build. A wide choice of colours and wood-effect finishes gives you plenty of freedom to match your new windows perfectly to your home.
Who is greenEvolution Free suitable for?
- Homeowners who want to keep the classic look when replacing windows in an older building
- Renovation of apartment buildings and rental properties
- Builders planning an energy-efficient home or passive house
- Anyone who wants large, bright window areas with slim frames
