AddOn window profile

An innovative window that includes an integrated shutter and sunshade system. Furthermore, an additional glass pane serves to enhance the thermal and sound insulation values.

The shutter and sunshade system ensures your well-being in your home – and is protected from all weathers between two glass panes. It can be operated manually or with an electric motor. This aluminum compound sash is available as a unit together with the window or as a separate retrofit.

The system, therefore, enhances living quality, saves energy costs, and reduces CO₂ emissions on a sustainable basis.


Features and Benefits

  • Extraordinary thermal insulation compared with aluminum windows. Typical U-values are between 0.21 - 0.23 Btu/hr-sq ft-°F

  • Steel-reinforced chambers for effective protection against unwanted intruders.

  • Excellent sound reduction properties - Up to 46 dB.

  • Unlimited choice of RAL colors and finishing techniques such as anodizing and powder coating.

  • Available in Parallel or Tilt Turn opening for maximum ventilation and security.

Alternative sunshade system

We can also supply a range of fabric sunshade systems that are integrated into the window frame. Contact us for more details.

Technical Drawings

We provide a full range of technical drawings for every project and work closely with the architect to overcome any obstacles during the design phase. We are on hand 24/7 if you need to use our expertise.

All of our technical drawings are shown in mm for precision.  If you prefer to receive drawings in inches, our team of designers and planners will happily make the conversion for you. 

Every window we manufacture is designed from scratch to suit the needs of the building, so the dimensions, glazing, chambers, and steel reinforcements shown in this image may be different depending on your project specification.
