OS2 75 is part of the OS2 family of systems that were designed to replace the windows and doors used from the nineteenth century up through the middle of the last century. This thermal break steel window comes in over 40 profiles, from just 27 mm to 62 mm and with a depth of 77 mm. The endless variations of OS2 75 are great for architectural projects that want to design every detail of the window or door frame as you can carefully calibrate the edges to modulate the play of light and shadow on both the exterior and interior. OS2 75 allows you to create various types of openings that can be freely composed in infinite combinations in the glass curtain walls: the tilt & turn sash can have 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.
The performance of the OS2 75 thermal break system has been tested by the best European certification laboratories in compliance with the current specific standard EN 14351-1 regulations.
Design Variants
The small profiles of this system are meticulously designed so that the outline of every line and fold is essential for reaching very high thermal and acoustic insulation performance. There are over 40 profiles to choose from to provide a solution for any formal or functional project requirement and to create the desired window or door in detail. For glass curtain walls or three-dimensional façades, light screens, or doors and windows, the choices offered by the OS2 75 system are many and varied: the profiles can house flush-mounted and non-flush-mounted glass panels, enhance the borders of the mono-colored area of the windows that make up the front or render them imperceptible to the eye, and put together sashes with fixed panes or those which can be opened compatibly in the design of the façade. To better distinguish the various choices, two subsystems were created: OS2 75.1 and OS2 75.2. With OS2 75.1, the glass panels are not flush-mounted and the profile of the frame emphasizes the perimeter of the sash. With OS2 75.2, the glass panels are flush-mounted and the profile sections can be continuous, both in the fixed uprights and in the perimeter of the sashes.
System and Performance
OS2 75 doors can be inward-opening or outward-opening. The OS2 75 door is an integrated system with accessories, gaskets, and thermal break profiles with a depth of 77 mm that allow for a wide range of rectangular, curved, or shaped doors. Double glazing up to 50 mm can be installed.
The sealing characteristics of the door frames are guaranteed by open joint system with a central sealing gasket and an internal stop gasket on three sides and an automatic guillotine gasket under the base on the inward-opening door system and by a double rebate gasket system and an automatic guillotine gasket under the base on the outward-opening door system.
Size and Variations
OS2 75 is an internally and externally rebated system with 47 mm face lateral sections and a 62 mm central section. For frames with multiple lights, a 36 mm thermal break profile is used.
Handles
For both inward-opening and outward-opening doors, the handles are available in paintable raw brass, burnished brass, polished chrome brass, and polished brass. The medium square version is also available in corten steel.
Hinges
For both inward-opening and outward-opening doors, the three-wing hinges are adjustable and available in galvanized steel, stainless steel, burnished stainless steel, and corten steel. The hinges to be welded are available in galvanized steel with versions h.80|d.13mm and h.116|d.16mm being adjustable.
The OS2 75 system can also be ordered as sliding doors, folding doors, and horizontal and vertical pivot doors.
