In 1954, Trocal launched its first serially produced plastic window on the market, and by the 1970s developed window profiles with a center gasket in various colors. The company from Troisdorf declared sustainability as its main priority and aimed to achieve significant progress in plastic window recycling and use of recycled materials. Many production processes improved thermal insulation of produced plastic windows and doors, while at the same time great potential of modern design for architects and building owners remained of utmost importance. As a result, Trocal offers a wide range of colors and surface textures. One of the company's main pillars are window profiles that combine aluminum and plastic in an intelligent way. The aluminum shell enhances structural stability and serves as weather protection, while plastic components ensure excellent insulation performance. Trocal-Profine holding has locations in 20 countries worldwide, up to India and China, and delivers products in more than 70 countries. The company originated from the split of Karl Kömmerling chemical factory in Pirmasens, which produced adhesives, in 1897.

The company was founded in 1935 in Stuttgart by Wilhelm and Elfride Frank and is now headquartered in Leinfelden-Echterdingen, with the name changed to Roto Frank AG.

Roto Fensterbauer supplies fittings and handles for windows worldwide, produced in factories in Germany, Hungary, France, Poland, China, and the USA.
