Plastic Windows

Structural glass bonding in plastic windows makes the windows stiffer and increases productivity. Bonding improves the dimensional stability of the windows, even without steel reinforcement. Utilising bonding technology, the design is no longer determined by the size of the steel reinforcement. Delicate frame structures for maximum sash frame sizes are possible. Sash frame heights of more than 2.5 m and weights of up to 130 kg are possible without steel reinforcement. Permanent bonding of the glass and frame prevents settling of the window sash. On-site adjustment of the sash frames is no loner necessary. This saves money and increases utility. Reduced frame dimensions results in more glass, more light, and better thermal insulation. Conventional blocking in plastic windows is manual work. Automated glazing is possible with bonding technology. Automated glazing and reduced use of steel increase productivity significantly.

Wood / Wood - Aluminium

Structural glass bonding makes wood–aluminium windows competitive. For many decades, wooden windows have been losing market share to plastic windows. Long-term use of wooden windows incurs high maintenance costs. Periodic painting is necessary to protect the windows against rotting. Exterior aluminium shells provide natural weather protection, which explains the increasing popularity of wood–aluminium windows. They have higher costs than plastic or wooden windows. Consequently, wood–aluminium windows are designated as premium windows. In wooden windows, bonding technology utilises the glass to provide natural weather protection. The glass covers the sash frame frames and thus protects them. This saves time and material.


Structural glass bonding in aluminium windows improves insulation and reduces costs. In order to be able to provide energy savings in keeping with present and future legislation, modern aluminium windows use plastic profiles for thermal insulation. Well insulated frame structures consist of a large number of components. Increasingly stringent requirements increase the complexity and boost costs. Bonding technology in aluminium windows utilises the insulation glass for the thermal insulation of the aluminium profiles. The insulating glass, with its better insulation characteristics, covers the sash frame and thus facilitates improved energy-efficient aluminium windows with simplified frame structures.

Structural Glass Bonding

Structural bonding of glass into domestic window frames provides a variety of benefits both to the window producer and his customers. The structural adhesives allows the rigidity of the glass to stiffen and support the window sash. This will provide increased flexibility in design and can reduce the need for additional steel stiffeners within the frame, reduce the size of the sash frame, resulting in increased natural light within the building. The bonded window system also provides a more stable window, as the sash does not rely on blocks being used to position and hold the glass in place. Therefore, the glass is firmly held in place and will not move as it is bonded on all 4 sides, preventing any movement or distortion of the sash.
