The minimal thermal break system
in precious metals, winner of the Compasso d’Oro Award

OS2 75

OS2 75 is the thermal break window in precious metals, with minimal profiles of 27 mm, central node between the two windows of only 62 mm, depth of 77 mm for glass up to 50 mm. The system is the only one that has all types of openings, tilt and turn, bi-folding, pivot, lift and slide, anti-burglary, providing you with the option to always have the same section in sight.


There are more than 40 profiles to choose from, where you can find solutions for any formal or functional project requirement. The profiles can house flush-mounted and non-flush-mounted glass panels, enhance the borders of the monocoloured area of the windows that make up the front, or render them imperceptible to the eye, put fixed or openable sashes correspondingly in the design of the façade.

To better distinguish the various choices available, we have created two subsystems: OS2 75.1 and OS2 75.2.


Sashes can be easily distinguished in the front view,
glass panels which are not flush-mounted between sashes and fixed panels


Regularly spaced nodes between sashes and fixed panels, and also with coplanar glass fixings


the central node of the double-leaf door has a reduced section while the profiles framing it are pronounced


the profiles of the perimeter of the frame have the same design as the central node


The small profiles placed in front of the glass to fix it are also design elements of the frame and are produced in the same finishes as the window


To better integrate into the window frame, the hinges are slender, minimal and provided in the same finishes as the frame.
In tilt and turn, the hinges can be concealed.


Discrete, geometric, minimal and in the same finishes as the frame, the handles integrate perfectly into the frame.


OS2 75 is also available in 4 precious metals in the Bi-material combination, combining two different materials between the interior and the exterior
