The installation heights are specified individually for each product as the height of the entire system (from the upper edge of the raw floor to the upper edge of the system floor), i.e. without any floor covering above the system floor. Deviating (smaller/larger) body heights are sometimes possible as special constructions. For the clear dimension of the ceiling cavity available for pipe installations, the thickness of the base/wear layer must be subtracted. Depending on the application, the System Flooring Directive (SysBöR) may result in increased fire protection requirements if the cavity is designed with a clear height of > 200 mm or > 500 mm.
