More about this product

OS2 65 are thermal break steel windows by Secco Sistemi for 40mm glazing. The performance of the OS2 thermal break system has been tested according to the current specific EN 14351-1 regulations.


The system is part of the OS2 family of profiles by Secco Sistemi designed to replace casings from the nineteenth century up to the middle of the last century. It is also used in contemporary architecture for its transparency and clear-cut lines, with slender profiles that 'dematerialize' the walls and allow for greater freedom in the design of the casing.

Design Variations

OS2 65 is a flexible and versatile system for realizing infinite fixture variations and for designing in detail the exact window or door required, with minimum sections and high-quality performance. When it comes to glass curtain walls, the OS2 system can compose together fixed and openable elements 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.
