The German manufacturer Siegenia-Aubi sells progressive fittings on the market for window systems, which are known for their reliability, ergonomics and functionality. The manufacturer’s assortment includes several model lines that differ in specific applications, technical specifications and dimensional parameters.
In addition, Siegenia-Aubi hardware regularly presents innovative solutions in the window mechanics segment, which contribute to improving the insulating properties in the overall structure of the double-glazed windows.
Siegenia Hardware Overview
Metal-plastic window structures have won the trust of the consumer due to many advantages. Among them are physical resistance and warming function, as well as an aesthetic appearance, thanks to which such systems can fit into any facade. In turn, accessories that ensure the operation of window systems made of plastic and metal remain in the shade, although their role can be called fundamental in the composition of structures. This is especially confirmed by Siegenia hardware, which guarantees the possibility of long-term and trouble-free operation of the double-glazed window. The products are presented with a wide range of elements, including hinges, handles, locking mechanisms, sealing components, as well as a wide selection of connecting components, linings and angles.

Most hardware products of this brand are made of high-strength metal with a corrosion-resistant coating, although there are also elements made of hard plastic, silicone and various types of rubber. At the same time, Siegenia hardware is environmentally friendly, does not spread unpleasant odors and is fully suitable for use in residential premises.
Varieties
First of all, all models of hardware products of this brand should be divided into two groups depending on the designs for which they are intended. These are window systems made of plastic, as well as combined structures that use aluminum. By the way, the first category is also suitable for use as part of wooden systems, although they are used less and less.
So, the hardware for plastic windows Siegenia presents classic mechanisms, including devices for mounting on a profile, performed before the formation of the sash. These systems include the Titan complex. Perhaps the most popular system designed for basic plastic constructions is the Favorit series accessories - these are swing-out mechanisms designed for the device of the main working configuration. Also popular are models that continue the concept of tilt and turn systems - for example, mechanisms with a roller locking pin.
As for hardware designed for aluminum window structures, it is represented by models designed to ensure the operation of complex lifting and sliding systems, which also combine functionality and mechanical strength.
Titan Series
In this series, one of the first systems is presented, which makes it possible to realize the installation of window fittings on workpieces from profile structures prior to the direct welding of the shutters. In practice, this means increasing the flexibility of installation, as the fittings are not associated with one work area. The use of roller trunnions also increases the reliability of the work of the main mechanisms. There is still room for manual installation of elements without using a special tool. In particular, the hardware for Siegenia windows in the form of corner hinges and an error blocker is integrated into the system by elementary docking. At the same time, the quality and accuracy of installation is controlled by the system itself - deviation from the norm during installation is not technically possible.
Favorit Series
This kit is a tilt-and-turn system that ensures the safety of the window mechanism. A design feature is the possibility of modular retrofitting, in which the user individually forms the operational properties of the kit, taking into account the requirements of the window. The manufacturer also attributes the versatility and interchangeability of parts to the advantages of the line. That is, Siegenia Favorit hardware can be used in classic trapezoidal structures, and in arched windows.
Not so long ago, engineers completed work on a modification of the system, as a result of which the Si-line kit appeared. This mechanism is characterized by increased protection against hacking.
A300 Series
Another variation of the swing-out hardware, which is based on a locking pin with a roller mechanism. But unlike other similar systems, the A300 provides the ability to adjust in three planes. It is worth noting the stylistic performance of accessories of this line. Designers have combined modern and classic features, which is optimal for use in a private house, and for the integration of elements in the construction of commercial buildings.
Also, Siegenia window fittings in this series received a technological protection against arbitrary slamming. An optional sash-lifting system with a built-in protection against erroneous actions is optionally offered. Users of this kit note the ease of management. In particular, the rolling roller, which is integrated into the locking trunnion system, is configured in three directions, after which it ensures a soft and smooth running of the hardware components. For additional protection, the system can be provided with an anti-burglary mechanism and hidden loops.
Trident System
This is special equipment for window structures that open outwards. The mechanism works on the principle of anti-burglary drive, but also has several features. In particular, the workflow involves the mutual coupling of the anti-burglar pin and the additional hook with the counter element on the frame in opposite directions.
The protection system also implements a restriction with a restrictor that allows the sashes to be opened up to a distance of 10 cm. According to users, the optimum position that such Siegenia hardware takes is on the side of the lock at the level of the handle. When closing the wings, the limiter automatically switches to the safety cocking position.
Energy saving scissors
The manufacturer’s unique developments include energy-saving scissors, which are included in an extensive package of additional options. This device makes it possible to optimally control the parameters of the open sash in accordance with current weather conditions. The mechanism works in conjunction with a fuse, which is also fixed at a level that meets the requirements of the home microclimate. Moreover, there is both a summer format for operating the system and a winter one.

In the warmer months, a ventilation function is provided. Since the gap in the summer should be as large as possible, it is recommended to adjust the limiter accordingly, which will protect Siegenia mechanisms from unexpected blows. The hardware for metal-plastic windows in winter provides for setting the sash gap in the tilt position to 4 cm. Reducing the gap not only increases the reliability of the system, but also favorably affects the minimization of energy consumption. In a closed, sealed form, the sound insulation function is also effectively performed. However, this indicator already depends on the quality of the basic design.
Positive feedback on hardware
Owners of windows equipped with Siegenia devices emphasize the high degree of reliability and durability of the component base. Wear resistance allows you to save parts for many years without the need for updates. Experienced users praise the modular design of the systems, which makes it possible to facilitate the modernization of windows. For example, if in the basic modification the kit did not provide for fuses, then in the future they can be integrated into the system even without the help of specialists. Separately, the external aesthetic appearance with which the Siegenia Favorit hardware is endowed is also noted. Reviews indicate that this product can be integrated into premium window systems and models with unusual design solutions. In such combinations, there are no stylistic or structural limitations.
Negative reviews
It should be noted that the higher the quality and operational capabilities of engineering structures, the higher their cost. The same applies to products of the German manufacturer. Even in the initial segment of Siegenia hardware, reviews of which also emphasize high quality, it costs 20-30% more than standard solutions from competing companies. Perhaps this is the main disadvantage of the product, since there are no significant complaints about the work.
Conclusion
Not so long ago, the main struggle in the market between window system manufacturers developed in the direction of improving insulation qualities, strength and durability. Additional accessories still play a significant role in maintaining these qualities. German hardware Siegenia, in turn, offers not only an increase in the basic characteristics, but also an extension of the control capabilities of window systems. The introduction of mechanisms for limiting, regulating and controlling the position of the flaps made it possible to optimize the process of operation of double-glazed windows. At the same time, the company seeks to universalize its systems so that owners of ordinary plastic and aluminum structures can use them.
