The FERROLINE system is a solution suitable for renovation of old buildings and ensuring the appropriate appearance of the windows. The windows may imitate steel joinery, maintaining at the same time very good technical parameters of the entire construction.
It is possible to make different types of windows based on the FERROLINE system – outwards-opened, inwards-opened and fixed windows – with a very good sound insulation as well as water and air tightness.

The renovation window frames available in the system allow to mount new windows without the need to disassembly the window frames. This option, apart from eliminating the risk of damaging the wall, allows you to save money and time.
