Why is a vapor barrier needed?
Water vapor can cause serious damage to your home. For instance, if your flooring gets wet, it could cause mold and mildew, and even destroy your floor. No one wants that, so vapor barriers are there to help prevent the floor from getting wet.
Also known as a moisture barrier, a floor vapor barrier is typically a sheet of plastic that slows moisture from moving through a wall or subfloor. A moisture barrier is used when installing floors or walls in areas prone to dampness or excess moisture, such as basements, ceilings, or crawl spaces.
Flooring moisture barriers are placed beneath the floor’s underlayment. You can buy a barrier separately or get underlayment with a moisture barrier built-in. If any water vapor penetrates through a concrete subfloor, the vapor diffusion retarder slows the movement of the moisture, preventing damage to the floor.
