Windows/doors with minimum sections and high performance, with endless variations in the profiles and types of openings
OS2 75 is part of the group of OS2 systems studied, conceived and designed by Secco Sistemi to replace the doors and windows used from the nineteenth century up to the middle of the last century. This thermal break steel window comes in an array of more than 40 profiles, with visible sections reduced to the minimum: from just 27 mm to 62 mm and 77 mm depth. The endless variations of OS2 75 correspond to the needs of an architectural project which designs the window in every single detail, calibrating the borders with care to vary harmoniously the play of light and shadow on the façades, both interior and exterior. OS2 75 offers the possibility to design different types of opening that can be freely composed in endless combinations in the glass curtain walls: the tilt & turn sash comes in dimensions of up to 130 x 290 cm with glazing panels of up to 50 mm, with concealed hinges and break-in-resistant closing mechanisms. Pivoting and hinged fixtures increase interior space with sashes of up to 100 x 290 cm, with reduced dimensions and thin, congruent section profiles. The sliding hinges, bottom and top rails are concealed when the doors are shut. The performance of the OS2 75 thermal break system has been tested by the best European certifying laboratories in compliance with the current specific standard EN 14351-1 regulations.
