vapor barrier on ceiling

[kerwinq]

When putting drywall on a ceiling do I need to put a vapor barrier on first?

Thanks

I would suggest getting in the attic and looking at the other areas of the ceiling. If it has it I'd put it in.

I just got through remodelling my bathroom/utility rooms and there wasn't any vapor barrier there so I didn't put vapor barrier in when I replace the sheetrock.

note: I'm in Oklahoma and the rules may be different where you live.

I live in Ohio & have helped build several houses over the years including mine & have never seen a vapor barrier used in a ceiling. I just finished my own detached workshop & you guessed it no vapor barrier. Not sure why though.

In general, yes you should apply a vapor barrier to the inside face of the insulation. The purpose of the barrier is to retard vapor transmission through the wall or ceiling assembly and therefore minimize the condensation of the vapor into liquid which destroys the R value of the insulation.

The rules for vapor barrier change depending on what part of the country you are in. You need to find out what the local practices are.

Holmes on Homes does...

Check your local building code. My building code does not require a vapor barrier if the space above is vented attic space.

When I was younger and building homes for a summer job, we always put in vapour barrier on all wals and ceiling. Even homes I've seen built or remodelled today put in the VB.

as has been said, ya need to check around where you live, its diff in diff areas. i did it for a customer once here in Missouri and it made the house swet, had to go back, pull the insulation back and cut it, after a week it dryed up.
