This is because, during winter, a lot of heating is produced inside the house. It is only those that experience extremely cold weather in climate zone 7 that will truly need vapor retarders on their insulation. While places in climate zones 4 and up may require vapor barriers, but not always. Generally, if you are living in the southern United States, climate zones 1 through 3 will not need vapor retarders. You may refer to this guide on the different climate zones in the US. Choosing a Vapor Barrier for Your ClimateĮxperts recommend that you choose which barrier based on the climate of your location. Since air also packs a significant amount of vapor in it, both of them can be easily mixed up when choosing what type of barrier you will install. Their main difference is that vapor barriers are specifically designed for moisture brought by air. A well-installed vapor barrier can both regulate air and vapor simultaneously. Vapor barriers and air barriers work similarly to one another. Which are better: vapor barriers or air barriers? On the topic of mineral wool, we have a previous article written about it: " How Long Does Mineral Wool Insulation Last?" Go ahead and check it out. In simpler words - they are specifically designed to prevent moisture accumulation to preserve insulative materials. In fact, they do not even serve as barriers but as a diffusion retarder. Vapor barriers alone do not control air movement instead, deal with moisture brought about by water vapor. The barrier's main job is to regulate air from interacting with the insulation, vapor barriers only control the moisture and nothing else. They help protect the insulation from the build-up of mold that can post heath hazards and rot the insulation. The job of vapor barriers is to control the movement of water vapor in the insulation. We will also tackle topics such as which insulation is better and if you can put the same insulation over the other. Interested to learn more things about faced insulation and vapor barriers? Continue reading below as we discuss these two in detail below. This is because the type of barrier you use should depend on the type of weather your location experiences. In fact, in some parts of the United States, it is better to not add vapor barriers as they can do more damage than good to your insulation. Since vapor barriers are only additional protection and not required to finish faced insulation, they are not always necessary. In this article, we have scoured the internet to give you the definitive answer to the question. You may wonder if faced insulation needs a vapor barrier. One common insulator is faced insulation. Insulating your house is one great way to keep it warm and reduce the cost of heating.
