"An appropriate type and thickness of XPS rigid insulation will be a vapor barrier (check the perm rating for your local products). If the seams and perimeter are sealed, and especially if the XPS is glued to the concrete, you will have a vapor…"

"The foam is a barrier & besides in all cases - no plastic sheets above concrete. If you are really worried about water you would use a product like dricore. As for high humidity - you might want to try to find out why - dry basements should…"

Vapor Barrier on top of basement concrete

Happy New Year!   Hoping this will be a great year for all of us to help our communities to save even more energy than ever before!   I have a project on a small house built early 30's, two floors and basement and very leaky. Basement is dry and is part of the conditioned space from the beginning, with wood paneling, carpet and a fireplace. Since the new owners would like to use the basement about 10 hours a day instead of the possibly 3 hours a day on a space originally designed as a family…See More

Airsealing an old basement ceiling

Greetings everyone,    I have a weird question... On a non conditioned basement, many times I find tongue in groove pine strips on ceiling of basements and then a second layer of wood as the finish product. If foam insulation is out of the question, is there any real value on trying to air seal that basement ceiling before insulating? and if you do agree that it is worth the effort, then how would you go about getting that accomplished?    Thank you for your observations, Luis See More
