Windows and front doors are critical to the design when planning a building or renovation project. A harmonious overall design can only be achieved if window forms and proportions, frame colours and the layout of mullions all complement each other.

Depending on taste and house type, architects and builders can choose from among a variety of styles in the window and door systems on offer: The systems available include those with rounded, soft con-tours offering clear, straight lines or innovative systems for state-of-the-art window design.

The system structure of all profiles is standard however, irrespective of the design: They always have a frame and a casement, reinforced steel, seal and glazing bead.
The differences in the systems are also distinct in type and positioning of the sealant as well as in the individual compatibility of the 70mm profile systems.
