greenEvolution Free: more light and a classic design

windows


The greenEvolution Flex you know so well is getting a new look. We are introducing gE Free to our offer – a PVC system for those looking for maximum interior illumination and traditional aesthetics, but without compromising on energy efficiency. Thanks to this system, you can reach a new group of investors.


Bet on a classic in a modern edition

Customers who miss traditional aesthetics but do not want to give up modern thermal performance will reach for greenEvolution Free. If an investor wants to maintain the classic form of a building when replacing windows, e.g. when renovating a tenement house, this system is for them.

The very low profile combination and narrow mullions of gE Free allow you to design a large, elegant space bathed in natural light, which is a response to dominant architectural trends. Furthermore, the flying mullion construction, which maintains symmetry thanks to the central handle, makes an excellent impression.
