OTTOSTUMM supplies components for fenestration systems.with a line of architectural bronze known as BronzoFinestra. The 75 TB system, consisting of 25 profile geometries, represents the most technologically advanced thermally insulated steel window system in the OTTOSTUMM portfolio and is available in architectural bronze under the system name BronzoFinestra B75 TB.
The profile depth of 75 mm can accommodate highly energy-efficient insulating glazing up to 52 mm and the fiberglass-reinforced polyamide insulator gives excellent thermal insulation, making the system ideal for projects in climatically demanding regions, where energy-saving regulations can be extremely high.
The assortment is rounded off by a wide range of exclusive fittings and accessories reproduced from original modern-age designs. This ensures that all common opening types can be realized (inside and outside opening) for windows and doors, including tilt and turn windows. The system is available with a flush or overlapping design.
The steel billets, rods and strips, from which OTTOSTUMM window profiles are formed, are smelted from almost 100% recycled steel scrap. At the end of their life, the windows can be systematically dismantled and the frames, fittings, and glass recycled.
