gwb detailing at wall ceiling intersections
« on: January 14, 2005, 08:13:41 PM »
Hi,
Is it necessary to isolate the vertical gwb from the ceiling gwb in a sound assembly. If so, does one use a j-mold at the top of the vertical with fire-rated sealant, in lieu of taping the corner joint.

Are there specific products for this. This is GWB to GWB, not acoustical board. Also. 2 layers on Ceiling, 1 on walls.

Thanks,
Jon
