FerroFinestra W75 TB
The FerroFinestra W75 TB system is the latest development from Ottostumm. The W75 TB system features slim lines and a visible and tactile surface. This system represents the most technologically advanced thermally insulated steel and glass system in our portfolio. The 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.
