The 82 mm installation depth and multi-chamber profile help reduce heat loss. The system supports high-performance triple glazing, improving the overall energy efficiency of the windows.
The MD system uses three seals to improve the airtightness of the window. This helps protect against draughts and moisture while also supporting better acoustic insulation and year-round comfort.
The robust profile construction and steel reinforcement provide excellent stability, including for larger window units. The system is designed for reliable operation and long-lasting performance.

82 mm installation depth: both the frame and sash are suitable for new-build projects and the renovation of existing buildings, providing a robust foundation for energy-efficient windows.
Glazing options: the system accommodates insulating glass units ranging from 24 to 52 mm in thickness, allowing the glazing specification to be adapted to the requirements of the project.
Sealing system: specially designed seals provide a high level of weather protection, helping to keep out cold air and moisture while reducing outside noise for greater comfort indoors.
Thermal insulation: the seven-chamber frame, combined with suitable triple glazing, can achieve a whole-window U-value below 0.8 W/(m²·K). This provides excellent thermal performance and helps reduce heat loss through the windows. The actual Uw value depends on the window’s dimensions and configuration.
Steel reinforcement and profile quality: galvanised steel reinforcements with a specially folded design are fitted in both the frames and sashes as standard. They provide the rigidity needed for reliable operation over many years. Only Class A profiles are used, supporting the quality and durability of the window construction.
Classic design: gently rounded edges on the frame and sash create an elegant appearance that suits a wide range of architectural styles. The 13 mm hardware groove axis allows for security fittings that help improve resistance to forced entry.
Window hardware: the windows are fitted with hardware from Winkhaus, a German manufacturer specialising in window and door fittings.
