Accordingly, which side of 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.
One may also ask, which side does the vapor barrier go on? In order to prevent condensation from forming, a vapor barrier should be placed on the warm side of your insulation to stop warm, moist air from condensing on a cold surface inside your wall. In cold climates like Canada, for most of the year the vapor barrier should be on the inside of the insulation.

Do you have to tape underlayment?
The answer is no. We recommend to use duct tape as every hardware store carries this product. Some manufacturers sell specialized tape for underlayment but there is no extra benefit.
