MB-FERROLINE is a window system with thermal barrier that is the perfect solution for renovating historical building while retaining the proper window visual design, imitating steel carpentry and with very good structural parameters. This system allows constructions to be perfectly adapted to the building's specific design requirements.

Versatile system for various types of windows with opening towards the interior (oscillating, swing, oscilo-swing), with opening towards the exterior (oscillating or tilting) or fixed, with very good thermal and acoustic insulation, water and air proofing and high strength.

Several exterior profiles available. Renovation frames are avalable to allow fitting new carpentry without removing old frames and avoid damaging the walls around the windows. Visible width is adapted in ways to minimize visual differences between old and new windows
