Is there a height limitation in sub-floors protected by DuPont™ FM-200®?
In general, there is no limit to the height of protection in a sub-floor. In fact, if the sub-floor were 3 meters high it would be treated exactly like a room for purposes of design. Each manufacturer maintains a system listing to a maximum nozzle height. Rooms exceeding this height are effectively protected using multiple layers of nozzles, each layer remaining within the height limitation. There are minimum heights for sub-floors to account for the practical installation of nozzles and piping. Limitations on system design are the responsibility of the specific system manufacturers and their respective listings and approvals. You should contact your specific system manufacturer for further clarification of the limitations on their particular system.
