NEW
Our CFS renovation solutions have been expanded! In addition to the proven CoxHYBRID® CFS PP range, we are now also introducing our innovative CoxDENS® PP Flex CFS solution in Ø 110 and the versatile CoxDENS® PP Flex Multi range in Ø 60. This makes it possible to renovate a CFS system, even if the system contains one or more bends and offsets.
Efficient, flexible and fully tailored to modern renovation projects.


Especially developed for connection to modern, condensing, high efficiency boilers with a maximum flue gas temperature of 120°C (T120).
