Overlaping vapor barrier?-how much?


When I have to overlap my vapor barrier, how many inches do I have to overlap?

Also, should I seal the overlaped seam or just leave it with the staples?

Another question, please.
Where I have cut out the insulation for the outlets, do I put any duct tape around it, or should I just leave the insulation right up against the box?

Thanks very much.

Y.M.,

My first question is this:

Did you use paper faced insulation? (I think you mentioned that you had)...If you did, then the paper face should be facing your warm area and ...that treated PAPER FACE - is your vapor barrier.
(DO NOT add another vapor barrier over that, or you will create a chamber for moisture to be trapped and cause problems)

If you are referring to the flat paper edge on the sides of your insulation batts, then you can overlap them if you want to. It is not required that these be overlapped. Most builders (us included) prefer to install them into the stud cavities, stapling the insulation sides onto the interior cavity sides of the studs. This allows the sheetrockers to locate and see the studs when it comes time to install the drywall.

Also: As far as taping around your outlets; Yes, that is a good idea. Tho I would suggest using 'tyvek' type or similar tape, since duct tape: is a little thicker, it can wrinkle easily and also bunch-up (you don't want that between your studs and the sheetrock) - Using a different tape is just a suggestion.

Thanks for the information.

The insulation that I have put in does not have any paper face on it.
It is just the batts themselves.

So I would have to put the plastic over it.
I just was wondering how much of a overlap do I have to have when I attach another piece of plastic vapor barrier?

I have purchased the 6mil plastic.

Thanks.
