OS2: an innovative system
for an increasingly sustainable architecture

The OS2 thermal cutting system comes from the need to be able to carry out perfect architectural integration on historic and monumental buildings, with fixtures similar to the ancient 19th century iron window. Also used in contemporary architecture in search of linearity, its sleek profile with thermal seal and the use of complanar glass, aims at greater transparency and allows great freedom in the design of the window. OS2 is therefore a unique system that blends essential features such as energy saving and eco-sustainability.

  2. Supporting glass up to 40mm
