Do you have to cover insulation with drywall?

A vapour barrier (sometimes referred to as vapour retarder) is typically a plastic or foil sheet used for damp proofing to prevent interstitial condensation from forming in various building assemblies such as walls, roofs, foundations and floors.
What can I use for vapor barrier in crawl space?
Use plastic sheeting to control moisture in your crawlspace. We use foil-faced rigid insulation to keep the space under the house dry. The plastic and the insulation will eliminate any moisture problems you have in the crawlspace, such as water droplets collecting on the concrete walls and pipes.
How do you get moisture out of a crawl space?
A wet crawl space could take a total of eight to 10 hours to dry. Warm, moving air picks up moisture more readily. To speed up the drying process, place a source of low heat, such as a light bulb, inside the crawl space and position one or more electric fans where they’ll blow air across damp surfaces.
Can you cover insulation with wood?

What is the difference between faced and unfaced insulation?
The Difference Between Faced And Unfaced Insulation Faced just means that kraft paper is attached to the insulation itself. The paper helps improve the sturdiness of the insulation so it doesn’t fall down as much. Unfaced insulation is just as good as faced, but it doesn’t have that paper attached to it.
Does drywall act as 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.
