Especially in warm, humid climates like Florida, it’s important to keep moisture where it belongs – outside your home. For years, builders and engineers alike have studied and applied the science of vapor barriers in construction. Vapor barriers are a layer of material that is designed to prevent the transfer of moisture. They can be installed on the inside or the outside of the home, and local building codes will determine which is more beneficial for your area.
In some cases, too many vapor barrier layers can be a bad thing. They’ll wind up trapping moisture inside the home. There are a lot of different types of vapor barriers, and while it is possible to add vapor barriers to an existing home, it’s much better to do so during new construction. There is a lot of science and research behind vapor barriers. For that reason and many others, it’s important to consult a professional on this topic.
