Pioneering PIB since 1938

Our company's founders were among the first to use polyisobutylene (PIB) for the production of roofing membranes to provide waterproofing and acid protection. And for good reason. After all, this new material offered vast improvements in terms of strength, formability and service life. The first synthetic rubber roofing membrane appeared on the market with the beginning of the post-war economic boom. It all started out with Schildkröt Kunststoffwerke AG in the '50s, and Braas & Co. GmbH then built on that legacy after it acquired the former company in 1971.

For example, with the introduction of the successful Rhepanol and Rhenofol roofing membrane systems, which were followed by further product innovations. In 1997, Braas Flachdachsysteme started to specialise in this area as an independent entity. Two years later, in 1999, the company changed hands, and Joachim Gussner took it over. This marked the beginning of a new era.
Braas Flachdachsysteme became FlachdachTechnologie GmbH & Co. KG or, for short, FDT. With the new name, the turtle reappeared in the company's logo.
