How do you vapor barrier around a window?
Cut a length of sheathing tape to secure the vapor barrier to the wall above the window, overlapping the perimeter of the window. Seal the rest of the barrier around the window’s perimeter. Pull back the vapor barrier at the floor and draw a bead of caulk along the wall near the floor.
How do you install an indoor vapor barrier?

Where does a Vapour barrier go?
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.

Plastic, specifically 6-mil polyethylene plastic, is the most commonly used vapor barrier. Plastic has a very low permeability rating, which means water, in its gaseous or liquid state, does not travel through it.
What is the difference between a moisture barrier and a vapor barrier?
Moisture barriers function to help in preventing water from entering inside of the wall cavity. On the other hand, vapor barriers basically prevent water vapor from the interior of the house to filter through the wall and condense on the warm side of the insulation.
Is drywall a vapor barrier?
The permeance of unpainted drywall is very high, generally between 20 and 90, so it’s not a vapor retarder at all. Meanwhile, air leakage through a 1 square inch hole in a sheet of drywall allows 30 quarts of water vapor to pass through the drywall under the same conditions. A third of a quart versus 30 quarts.
Can you screw through vapour barrier?
Typically, nothing is done. That puncture should be at a tight connection of drywall to stud, where airflow is impeded by the pressure of the screw holding the drywall and vapor barrier to the stud.
