Also, do you put Vapour barrier on interior walls?Normally interior walls do not require a vapor barrier, but there are some situations where it is highly recommended. The paint acts as a vapor barrier as well. A continuous plastic vapor barrier behind the drywall will protect the interior walls of these areas from water damage.Also Know, does Wall Insulation need a vapor barrier? After the insulation is in place you will want to add a vapor retarder, sometimes called a vapor barrier, if you need one. Not every wall does. A vapor retarder is a material used to prevent water vapor from diffusing into the wall, ceiling or floor during the cold winter. One may also ask, can you use house wrap on inside walls? The house wraps are designed to allow water vapor to pass through them, but stop liquid water. Vapor barriers are put on the inside face of wall studs in cold climates and they’re put on the exterior of homes in hot and humid climates. You want the vapor barrier as far away from the cooler wall surface as possible.Can you overlap vapor barrier?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.
