We are in the process of finishing our basement. I have been doing a lot of research and have read a lot of conflicting information on vapor barriers.

Our house is about 4 years old, poured concrete foundation. No water problems. A lot of humidity in the summer.

We are planning on using 2x4 studs, fiberglass insulation. Now, the 6 mil thick poly sheeting... should this be installed on the concrete wall, or in between the studs and the drywall? Thanks!

You have to research a little more into putting a vapor barrier on your basement walls. If your basement already has hig humidity; the vapor barrier will hold the moisture in your exterior walls. This can cause a whole host of problems; not the least of which is mold.

I have seen all the conflicting reports on this also, and it can be confusing. If your foundation was waterproofed correctly from the outside, you could be alright. If it was not you could be asking for trouble. Moisture is one of the single most damaging problems a house can experience.

I had a finished basement with a moisture barrier and insulation. The reuslting mold and moisture "ate" up the drywall and damaged a large section of my house's sill plate.

What is the final answer to all of this?


Good Luck
