Product description

OS2 65 is the thermal break steel window with profiles of just 27 mm - 47 mm for the lateral section, 62 mm for the central section and depth of 65 mm. It can house insulating glazing of up to 40 mm.

OS2 65 is part of the OS2 family of profiles, studied, conceived and realized by Secco Sistemi to replace the casings used from the nineteenth century up to the middle of the last century. Utilized also in contemporary architecture for the transparency and clear-cut lines, the slender profiles of the OS2 system 'dematerialize' the walls and allow for greater freedom in the design of the casing.

The performance of the OS2 thermal break system has been tested by the best laboratories of European certification, as according to the current specific EN 14351-1 regulations.
