For vertical direction changes of screed-covered underfloor installation ducts (wall connections, supplies).

An important precondition for correct underfloor installation is the screed structure.
In the case of a screed-covered system, it is important that the screed thickness of the duct is at least 35 mm, to avoid the formation of cracks (DIN 18560).
Screed height: 60 mm only for on-floor connection technology (Telitank), 70 mm or more for underfloor connection technology.
