The system of single-frame window with the wooden-aluminium construction is an innovative window construction based on the concept of two independent frames - the wooden one and the aluminium one - between which, an energy-saving insulating glass unit is placed.

The inner aluminium frame is the guarantee of real durability. The outer wooden frame ensures natural heat and friendly aesthetics.

Thus, the system proposed by us has all the positive features of wooden windows, ensuring at the same time many years of durability without the necessity of renovation, owing to the external aluminium frame.
