When air barriers are incorporated into wall systems, they are typically included to control air movement, control wetness and/or decrease power usage, or to avoid pumping due to wind, which can create uplift with mechanically secured membranes.


To reduce the possibility of interior air being pumped into the roof an air barrier must be situated at the roofing system deck level under the roofing system insulation, securing all roof covering deck gaps.

When the deck is utilized as an air barrier, deck penetrations such as plumbing vents ought to be secured, as well as the deck should be sealed at parapets.

Vapor retarders might additionally be needed to stop condensation under white or light membrane layers (amazing roofs) in cold climates due to the fact that the temperature levels of such membranes might be so reduced that also occupancies with low or average indoor moisture can cause condensation in such situations. As noted over, if the deck is a brand-new concrete deck, a vapor retarder should be supplied on top of the deck, to keep moisture inherent in new concrete decks from migrating into the roof system.
