The greenEvolution system is a new solution in the field of energy-efficient PVC window joinery, adapted to the requirements of passive construction. Its use makes it possible to significantly reduce heat loss and thus lower heating bills and reduce the carbon footprint. The enhanced parameters were achieved through the use of the MD centre gasket, improving the tightness of the window.

The classic shape of the profiles, combined with a wide range of available veneers, guarantees the ease of adapting greenEvolution windows to the vision of each investor.
