OTTOSTUMM supplies components for steel fenestration systems. The 75 TB system, consisting of 25 profile geometries, represents the most technologically advanced thermally insulated steel window system in the OTTOSTUMM portfolio.
FerroFinestra W75 TB and BronzoFinestra B75 TB are the latest developments from OTTOSTUMM. The designs recall the simple, rational and sober lines of early 20th century European architecture. The system is supplemented by a wide range of fittings and accessories reproduced from original designs of the modern era. It allows the realization of all common opening types (inside and outside opening) for both windows and doors, including tilt & turn opening mechanism. The system is available both flush and overlapping.
A profile depth of 75 mm allows the accommodation of highly energy-efficient insulating glazing up to 52 mm and the fiberglass-reinforced polyamide insulator guarantees excellent thermal insulation, making the system ideal for projects in climatically demanding regions, where energy-saving regulations are extremely high.

In addition to continuous galvanizing, versions in steel, cor-ten steel and stainless steel (1.4404) are available.
- BronzoFinestra B75 TB
With its unlimited surface shades, architectural bronze is a living material that gives windows and doors an undisputed charm.

The steel billets, rods and strips, from which OTTOSTUMM steel window profiles are formed, is smelted from almost 100% recycled steel scrap. At the end of their life, steel windows can be systematically dismantled and the frames, fittings, and glass recycled.
