give shape to the minimal

BV75

HistoryDuring the first English industrial revolution at the end of the 1700s, electric lighting was not yet widely used and natural light was used to the fullest to illuminate the working environments through the opening of large windows. The frames were built with simple steel profiles in the shape of T Z L to support small glass plates of about 30x30 cm, the maximum dimensions available at that time. The frames composed in that way had the typical checkerboard design called “Inglesina” due to their origin. The simple “T Z L” profiles evolved to adapt to residential buildings, changing the surfaces from flat to molded “beveled”; to decorate the frame, we continue to shape of the glazing bead and above all make the window profile similar to that of elegant wooden windows, more suitable for residential buildings and moving away from industrial aesthetics. Secco Sistemi re-proposes the “beveled” style with BV 75, profiles with a molded shape on the outside, to satisfy the most careful needs of designers both in restoration and in traditional buildings.

The external view is equal to the internal view.

has been designed to manufacture windows with the same molding on the outside and inside while maintaining the in-novative technology and high performance characteristics of OS2 systems. The beveled shapes of the profile and the glaz-ing beads are symmetrical with respect to the glass, in the axis of the window section. The frame thus takes shape, giv-ing the exterior elevation the same depth as the interior.

The farmhouse is set in the beautiful setting of the Tuscan countryside, a few kilometers away from Siena and is part of a a large project dedicated to the redevelopment of rural buildings.

The restoration has envisioned the maintenance of the original size of the windows and doors as well as the closing of wide arches of the porches using BV 75 windows for the

construction of new rooms. The BV 75 system has been used because of its profiles which are shaped like the original wooden windows and doors, creating continuity between the wooden and steel frames on the façade of the building.

Secco Sistemi is an Italian brand that symbolises innovation and design awarded with “Compasso d’Oro”. It has been contributing to the evolution of the engineering of doors and windows for 70 years, inventing systems and profiles that have become benchmarks for the industry of this sector, and continuing to improve them and interpret the latest projects and trends of contemporary architecture. So far 340 profiles have been developed in 4 select metals – galvanised steel, stainless steel, corten steel and brass – and in 9 different finishes with an annual production of 2.8 million linear metres of profiled bars for 280,000 doors and windows.
