Technical approval as testing, monitoring and certification body for chimneys, air-exhaust-systems, particle colector and further construction products

With the notification of 26. September 2017 from the Deutsches Institut für Bautechnik, the RRF is officially approved for further building products. Since we established ourselves on the marked being a testing, monitoring and certification body, we incorporated further important construction products into our portfolio: including room-sealed flue gas collectors both for solid fuels and liquid fuels, exhaust heat exchanger, catalysators, particle interceptor as both chimneys for houses and freestanding chimneys, air-exhaust-systems (LAS) exhaust gas lines and component parts of exhaust systems.

Of course, we offer you our competent service and technical knowhow for these building product groups like usual. We would be pleased to make you an offer about the testing or external control and certification of the above-mentioned product groups. Our staff is always available for your queries.
