Moisture barrier in garage.

Most garages don t need vapor barriers because the amount of vapor that diffuses through garage walls ceilings and the floor is not enough to cause wet walls that result in moisture damages. I have an unfinished garage. The attic studs and floor of the garage attic are configured in a way to allow the space to be finishe. My old garage which was expanded is dry.

My new concrete garage was poured over a heavy moisture barrier that i witnessed being used. Proper installation of a wall vapor barrier or using insulation products with a built in vapor barrier will reduce garage condensation a vapor barrier can also be used to cover the floor but avoid using it on garage ceilings. However if you live in a cold climate zone such as alaska it s a good idea to install a vapor barrier on the warm in winter side of the wall. Vapor barriers can help to keep condensation under control if installed in the right places.

Ceiling vapor barriers are a bad idea because they keep water vapor trapped inside the garage. Is this likely to be condensation that is more common with new concrete. This material adapts to let moisture out of the wall whether the humidity levels are higher on the outside of the wall winter or the inside summer.
