Vapor barriers can be a very complex topic, but it’s also a very important one. Vapor barriers are designed to keep moisture from permeating into your home, causing issues like mold growth. There are a lot of different types of vapor barriers that vary widely in efficacy. They can be thin, like a coat of paint, or they can be thick, like a concrete block wall.
In some climates, vapor barriers are essential. In others, having too many vapor barriers can be a very bad thing. In fact, Texas runs the gamut in the use of vapor barriers. Some parts of our state benefit from vapor barriers, and in others, only very minimal barriers should be used. If you’re building a new home or renovating an existing one, it’s a good idea to talk to your engineer or contractor about the vapor barriers they intend to use. Since this can be a very complex topic, be sure to consult a professional who knows what they’re talking about.
