AIR / VAPOR / MOISTURE
BARRIER:
Remembering that an air/vapor barrier keeps warm
moist air inside the building so that it will
not condense upon contact with colder outside
air and that moisture barriers keep moisture out
of the building enables one to easily see the
distinction between the two. Vapor barriers
should be placed on the conditioned side of
insulation. A common place for a moisture
barrier would be atop moist earth in a sub-area
crawl space. Improperly placed vapor barriers
may result in condensation which may lead to
wood rot. Be aware that the inspector may not be
able to fully review all vapor or moisture
barriers due to inaccessibility.
