W75 TB

Key Features

Minimalist Steel Aesthetics
The W75 TB profiles, made from hot-rolled steel, feature slim lines with visible widths of 27–49 mm, maximizing light penetration while maintaining an elegant, industrial character. Available in finishes such as powder-coated steel, galvanized steel, stainless steel, or Corten, they can be tailored to any project style—from modern to historic.
Versatile Applications
The W75 TB system supports a wide range of configurations, including outward-opening windows, tilt-and-turn windows, pivot windows, as well as single and double doors, pivot doors, sliding doors, and folding doors. Its deep profiles and high rigidity make it ideal for large glazing, curtain walls, and complex architectural structures.
Exceptional Durability
The W75 TB steel profiles offer three times the rigidity of aluminum, enabling large-scale glazing with minimal frame width. The system is resistant to deformation and ensures reliability in demanding weather conditions.
Superior Thermal and Acoustic Insulation
With a thermal break and the ability to use glazing up to 52 mm thick, the W75 TB system achieves heat transfer coefficients as low as 1.0 W/(m²K), meeting high energy-efficiency standards. High-quality seals and acoustic glazing (Rw up to 44 dB) effectively reduce external noise, ensuring comfort in interior spaces.
Security
The W75 TB system is equipped with advanced anti-burglary systems (class RC1, RC2, or higher) and multi-point locks to enhance security. Optional safety glazing (e.g., P2, P4) integrated into the structure further strengthens protection against break-ins.
Precision and Top Quality
Manufactured in Switzerland with the highest precision, W75 TB profiles meet stringent quality standards, certified by institutes such as IFT Rosenheim. High-quality fittings, available in various designs, ensure smooth operation and long-term durability.
