Does anyone have info on a fire rated assembly with wood strapping?
Its an Existing building, New 3/4" plywood sub floor, existing 2x12 joists (12 and 16" OC at laces) Existing 1x3 strapping, New 1/2" resilient channels, 5/8" Type X drywall.
All test reports I have found show the drywall either directly on the joists, or on metal resilient channels. None with 1x3 wood strapping.
From some reading, It seems wood strapping on the ceiling is a U.S., North East thing. With most other parts of the country not doing it (not sure about the world). Drywall goes straight onto joists elsewhere. I read the history of the strapping was to level the ceiling plain by shimming the strapping. In other parts of the country (world?), better quality wood was available so this was not done.
Thinking (hoping) this is why I can not find a tested assembly with wood strapping. And it is not an issue.
Thanks
