What division is vapor barrier?
Division 7
Can I use plastic sheeting as a vapor barrier?
In simple terms, a vapor barrier is a material that won’t allow moisture to pass through it, such as plastic sheeting. A very simple experiment to show how a vapor barrier works is to lay a plastic garbage bag down on some damp soil. There are two basic types of vapor barriers used with exterior wall insulation.
Where do you put vapor barrier?
Vapor barriers are usually best installed on the side of the wall that experiences the hotter temperature and moister conditions: the inner surface in colder climates and the outer surface in hot, humid climates. In existing spaces, oil-based paints or vapor-barrier latex paints offer an effective moisture barrier.
Should I put plastic over insulation before drywall?
Without poly beneath the drywall, water vapor hits the drywall and diffuses through to the drier (in summer) indoor air. By installing a sheet of poly there, you cut off that drying mechanism and water that finds its way into walls can stay there longer and do more damage.
Does moisture barrier go up or down?
The air is usually warmer inside the house, so condensation can build up from air entering the wall from the inside. The vapor barrier should point toward the room in this case.
Is a moisture barrier necessary?
When moisture penetrates your flooring, it can cause mold, mildew, and the potential for water damage. A moisture barrier helps control the water vapor’s movement to help protect your floors.

The rule of thumb is any vinyl over 4mm can have a vinyl specific underlayment. Vinyl floors under 4mm should be installed right over the subfloor. If you have any areas on a concrete subfloor with moisture concerns, it is recommended to use a vapor barrier underlayment that will not add any cushion to the planks.
Which side of the underlayment goes down?
Get started by rolling out the underlayment with the silver side facing down. The tape strip should be flush up against the wall. Leave the overlapping section on the side that goes out toward the room. You’ll need this section later as you continue to unroll your underlayment.
