In 1954 Trocal launched its first series-produced plastic window on the market and it had already developed its window profiles with a circumferential middle seal in different colours by the 1970s. The company from Troisdorf declared sustainability as its main priority and aimed to reach significant progress in recycling plastic windows and the use of recycled plastic materials. Many of the production processes obtained better heat insulation of the plastic windows and doors produced, but at the same time, the great contemporary design potential for architects and building owners remained of main importance. As a result, Trocal offers a wide range of colours and surface textures. One of the mainstays of the company are the window profiles, which combine aluminium and plastic in an intelligent way. An aluminium shell reinforces the constructive stability and serves as weather protection while the plastic components take care of the excellent insulation performance of the profiles. The holding company of Trocal -Profine has sites in 20 different countries all over the world as far away as India and China and delivers its products to more than 70 countries.  
The company emerged from the partition of the chemical factory from Karl Kömmerling in Pirmasens, which was producing adhesives, in 1897.

Schüco windows were considered as unsustainable products for a very long time. However, this negative prejudice shows lack of knowledge of the history of the company. Schüco is one of the first, most successful and biggest windows profiles producers from PVC, metal and aluminium, window fittings and further products for windows and facade engineering. In addition, it is part of the overarching body of the Otto Fuchs group on a worldwide level which has various aluminium profiles, building automation products, ventilation systems and building-integrated photovoltaics. The company was founded 1951 in Porta Westfalica by Heinz Schürmann and originally, it functioned as a metalworking company. At the beginning, their main production consisted of windows and facade systems from wood, aluminium and other metals.
In the 1970s PVC products were included in the portfolio and in the 1980s the company developed window profiles which made the current success of plastic windows possible. Nowadays Schüco delivers its PVC and metal profiles for window constructions to companies in over 80 countries worldwide.
The current main seat of the company is in Bielefeld. 

Since its foundation in 1937 Gutmann AG is one of the main aluminium producers in Germany. The company that was created by Hermann Gutmann is specialised in the production of light metal wires. At the same time, it continues producing aluminium wires of all kinds that are mainly used for aluminium profiles, but also for window construction, facades, doors and other purposes.
Two of the most representative projects which were implemented with profiles from Gutmann are the Allianz Arena in Munich and the Elbe Philharmonic Hall in Hamburg. Gutmann produced its first coupled window from aluminium and wood back in 1976. Currently, we are offering an improved version of these same windows. The use of wood and the profile design ensure excellent insulation values and the aluminium profile guarantees weather resistance and noble design. The wide range of variants allow for the possibility of appearance and constructive adjustment to the architectural parameters of buildings. 

The predecessor of the now global active company Winkhaus was founded in 1854 August Winkhaus and operated as hardware store in Halver at that time. Currently, the company is based in Telgte, Westfalia and is managed by one of the descendants of the company's founder. There are some subsidiary companies in Romania and Poland and in this way, the company opens new opportunities on the Eastern European market.
In the field of window construction, Winkhaus is an important supplier of 15 locking systems and security accessories. Still, a big part of the fittings is produced at its company site in Telgte. There are more than 700 people employed there at this time. 
Access control, alarm and time management systems are important mainstays at the moment. The company draws experience from a long company tradition and at the same time, it is pretty much in touch with the newest trends as which, for example, can be seen innovative security products.

Helopal is a business of the Austrian company Lottmann that was founded in 1928 by Max Lottmann to manufacture concrete roof tiles. They experimented with cast marble from Marble powder to produce window benches back in 1969. 1973 they came onto the market under the brand name Helopal. The thermal qualities and the outstanding machinability made this material a top seller among architects, developers and construction workers within a very short time. With the help of modern technologies, the processing of cast marble is unproblematic from the perspective of environmental protection and can compete with other materials for window benches.
The German location of the medium-sized company is the city of Bensheim. From there and from the branch in Chemnitz the company supplies the German market with innovative solutions for indoor and outdoor window benches. The cast marble material remains the main priority. However, Helopal offers a wide number of benches which are also made from other materials like steel and aluminium.

The company was established in 1935 in Stuttgart by Wilhelm und Elfriede Frank and today it has its head office in Leinfelden-Echterdingen, and its name has been changed to Roto Frank AG. Together with Roto N it developed the first tilt and turn fittings which make it possible to tilt and turn a window wing.

Roto Fensterbauer supplies windows fittings and handles worldwide and they are produced in factories in Germany, Hungary, France, Poland, China and the USA. Additionally, Roto is one of the main producers of roof windows which holds crucial patents for the tilt-turn mechanism that is used there. In addition, Roto offers great solutions for solar use of roofs in both the solar thermal and the photoelectric field. 

This product, which was patented in 1935 and the two years later developed tilt and slide attic stairs, formed the success of the Swabian company.

The company Maco was created in 1947by Lorenz Mayer as a fitting factory in the city of Altenmarkt in Austria. 1952 the family business was moved to Salzburg, where its head office is still based. Back in that time, the production took place at three main places in Austria - Salzburg, Trieben and Mauterndorf.

Furthermore, there are some sales office across Europe and beyond like for example in Brazil, Turkey and an assembly plant in Russia where semi-finished parts which were produced in Austria are set together. These sales offices make the supply of products to more than 40 countries possible. Maco is a leading producer of windows and doors fittings and in addition, it offers Austrian solutions for anti-burglary protection and self-locking. Further important products from the Maco company are the window monitoring, ventilation systems and corrosion protection. The company is a symbol of a traditional family business that takes social and ecological responsibility.
