i've been reading here and John Bridge to learn how to add a shower to my tub.
everyone always mentions putting a waterproof layer over the studs in the walls of a tiled shower.
makes perfect sense to me, but i just talked to my local plumbing inspector (portland OR) and he's never heard of the practice. his feeling was that cbu was sufficiently water-resistant (which is contrary to what i've been reading here). oh yeah - i talked to a local licensed plumber too. same thing: he's never seen anyone do it.
so what's the deal with this?
the Wonderboard pamphlet says "in wet areas, nail or staple 15 lb roofing felt or 4 mil PE sheeting to studs".
the HardiBacker pamphlet says "If required by Local Building Codes, install a moisture barrier between studs and backerboard".
i thought Portland just used the national codes. is this moisture barrier thing only in state/local codes?
comments please
