When fixing the glass panes the sash and the glass are glued together using a single component polyurethane adhesive. This extremely strong connection makes the overall window construction more rigid, so that the sash no longer requires steel reinforcement.

This technology has been used successfully in the automotive industry for many years and has been used in the manufacture of windows since 2005. Customers benefit from extremely good stability and increases in thermal insulation, soundproofing and burglar protection.

Using a new, precision, high-pressure insulating foam technique, three profile chambers in the ready-welded window are filled with thermal foam. This leads to a significant increase in the window’s ability to insulate and the associated values. With this innovative technology, this system is perfect for houses or other buildings with composite insulation systems and especially for passive houses. Thermal foam is able to achieve the highest demands for thermal efficiency.

Using this technology, the steel reinforcements in the sash and frame are replaced by a high-tech reinforcement called Ultradur® High Speed which can also be welded into the corners. The combination of the two materials creates continuous stability throughout the entire frame providing greater strength and more rigid corners than conventional steel reinforced windows. This cutting-edge technology has been used in windows for less than a decade and provides excellent stability in your new windows and doors.

For vinyl windows, a wide variety of decorative foils is available. These are applied directly to the vinyl surface during manufacture, guaranteeing long term color durability. Windows with decor foil applied in this way are impervious to scratching as well as resistant to the fading over time from sunlight exposure. You have a choice of classic patterns such as wood, as well as a variety of modern finishes and other popular window colors.

The energeto® stands out as a result of its classic profile type, but also due to the fine sections which optimize the available glass area. This ensures maximum sunlight in your home. This is even more important when renovating and buying replacement windows as you must work within the existing dimensions of your home’s windows. The total surface area of the glass, and thus the area allowing light through, creates as much natural light as possible for you.

The profiles for our vinyl windows are supplied by Aluplast, a well-known and respected manufacturer of window profiles located here in southern Germany. All vinyl profile systems carry the RAL seal of approval. For customers, that means the very best quality and regular external auditing and reviews of production. When purchasing windows and doors always look for the RAL seal of approval to be assured of high quality.
