OS2 65

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.

design of the variations OS2 65 over 40 slim, strong profiles to choose from to find solutions for all project requirements

OS2 65 is a flexible and versatile system for realizing infinite variations of the fixture and for designing in detail the exact window or door required, with the minimum sections and high-quality performance of the OS2 group of profiles. In the glass curtain walls, with the OS2 system fixed and openable elements can be composed together in various ways: by clearly defining the profile of the leaves in the façade with respect to the fixed mullions or struts, or by unifying the design of the casement using profiles with the same sections exposed everywhere. To better distinguish the various choices available, we have created two subsystems: OS2 65.1 and OS2 65.2 In the case of OS2 65.1 the panels are not flush-mounted and the profile of the frame goes to underline the perimeter of the leaf. With OS2 65.2, on the other hand, the glass panels are flush-mounted and the profile sections can be constant, both with regard to the fixed struts and in the perimeter of the leaves.

OS2 65.1

27/62mm
  1. sashes are well-defined in the front view
  2. non-coplanar glazing between sash and fixed pane

OS2 65.2

62/62mm
  1. possibility of sections always the same between sashes and fixed panes
  2. flush-mounted glazing between sashes and fixed panes
  3. sash
  4. fixed pane
pivot opening for large arch-shaped windows with single thin continuous profile framing the glazing With the concealed hinges the outline of the casement is continuous and seamless all around the perimeter
the casement represents the constant expression of the wall while the profile traces the perimeter of the sash along each side, including the one flush with the flooring
. in the double-sash windows the thin profiles tracing the perimeter of the casement have the same design as the central section in the front view
perimetral profiles in the front view have the same dimensions and design as those which divide the glazing into 4 parts
in the front view of the casement, the perimeters of the fixed and openable sashes have the same design
the congruent section profile designing the perimeter of the glazing panel makes the two-leaved door inconspicuous
