Ceiling Fire Protection

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Is anyone aware of an assembly that would deliver a two hour fire rating for
a ceiling supported by 2x or 3x joists at 24 inch centers? I thought a
couple of layers of 5/8 inch Type X gypsum board would do it, but apparently
not according to the UBC.
