OS 65

The thermal break steel window: slim, high-performing profiles of just 27 mm, multiple combinations available, insulating glazing of up to 40 mm

OS2 65 is part of the group of OS2 profiles, studied, conceived and created by Secco Sistemi to replace the doors and windows used from the nineteenth century up to the middle of the last century. Utilised also in contemporary architecture to satisfy the need for transparency and purity of lines, the slim profiles of the OS2 system lighten the walls of their weight and allow total freedom in the design of the fixture. OS2 65 is the thermal break steel window which comes in an array of more than 40 profiles, with visible sections reduced to the minimum: from just 27 mm to 47 mm for the lateral section, 62 mm for the central section and 65 mm depth. This steel window can house glazing panels for insulation of up to 40 mm thickness. With the many possible variations of the system OS2 65, moreover, the profiles can have glass panels which are flush-mounted or inset within the frame, which underline the borders of the sashes and blend into the unicoloured area of the fixed panes or be composed freely with the same design for fixed and openable sashes. The performance of the OS2 thermal break system has been tested by the best European certifying laboratories in compliance with the current specific standard EN 14351-1 regulations.

EBE 75 Info

The monumental complex of the Gallerie Dell’Accademia stands in the site once occupied by the big complex formed by the church of Santa Maria della Carità, the nunnery of Canonici Lateranensi and the Scuola Grande di Santa Maria Della Carità. From the 16th century until the second half of the 1940s, several architects worked on the complex of the Gallerie: from Palladio, Gianantonio, Selva, to Carlo Scarpa who was in charge of an important, although partial, renovation. low maintenance and, lastly, the use of a material that would fit in with the architectural context. For this reason, OS2 door and window frames in burnished brass were used. These not only fully meet the initial restoration requirements but also have a high resistance to corrosion, which is a vital requirement in a difficult and aggressive marine environment such as the one in Venice. The renovation aimed at expanding the space for exhibitions in the vast and articulated museum and it required a delicate yet significant intervention by the designer under the strict and competent supervision of the Sopraintendenza ai Beni Architettonici (Superintendence for Architectural Heritage). The requirements for door and window frames were very precise: minimal visual impact, high thermal and acoustic performance,
