I am looking for a 1-hour fire floor ceiling assembly (wood I-joists) w/min 45 IIC. I do not find anything that meets this w/out adding lightweight concrete to the flooring assembly. Have checked the GA manuals and the AWC documents, but no luck. Does anyone have any suggestions here? I am hoping to use an engineered wood floor as the finish above. This is for an accessory dwelling unit over a garage.
Thanks in advance,
