A vapor barrier is a unique membrane available for basements and crawl spaces, costing between$0.50 and $0.70per sq.ft. installed. This material is a durable plastic or composite membrane that lines the walls of the basement or crawl space to prevent moisture from penetrating the space. The ...

Basement Insulation Vapor Barrier The simplest way to prevent this water vapor from entering the space is to prevent air movement [moisture] into the basement by installing a vapor barrier. When properly installed, closed-cell foam (spray or rigid foam board) acts as a vapor barrier and insulat...
No vapor barrier. Reply Doris Todd, I read your article on insulating the basement. I understand the foam board goes right against the cement blocks (wall) and is taped to keep the moisture where it belongs. How do you know this method absolutely does not create any mold behind the foam...
You should select an insulation material that withstands the below grade (below ground level) environment - the wetting and vapor drive, and the freeze/thaw cycles. If you plan to leave the material directly exposed to the soil (outside the foundation wall), extruded polystyrene such as Dow'...
Once you understand that all foundations are full of water vapor you start to realize that the primary objective of the vapor barrier is stopping moisture from the foundation from entering into the finished framing where it might lead to mold. As you can see in the adjacent sketch the basemen...
As discussed above CCSPF can serve as a vapor barrier. In a finished basement with conditioned spaces, a vapor barrier is absolutely necessary to prevent moisture buildup and mold growth. In order to achieve a complete envelope for vapor and thermal protection, it is recommended to install all...
By installing the foam board you’re creating a vapor barrier that will prevent the moisture from getting to your framing, insulation and wall board. You’re also creating the first line of defense for a cold surface toward the heated zone. Again, as warm most air hits a cold surface it...
