GWB over Plywood
GWB over Plywood
(OP)
Can someone tell me where to find values for application of gypsum over plywood? Know this is commonly done for fire protection, can't find the table or line in the IBC for the reduction.
Have a similar situation where I was hoping to use these values.
Thanks

My understanding is the gypsum board provides some fire protection, I want to say its something like a 1 hour rating but not really my line of work...

I wonder if it has something to do with tested assemblies. If no one has done a fire rating test on a wood framed wall sheathed with plywood then covered with GWB, then it might be easier to cover a rated wall assembly with the plywood. I just can't see how it would be very pratical for anything but the interior face on a shaft wall. It would just seem that if the wall face was visible, that you would have to cover the plywood with GWB to finish off the wall face.
