Question
I have off grade flooring crawl space about 2' i have batts for insulations held up by screening i am finding condesation dripping off of it early morning and have a plastci 10 mil vapor barrier below grade with 2 inch of mason sand above it why is it condesating and would spray foam replacement cure my problem

Answer
hi Lori,
i think the crawl space may need venting...?
if its already vented, i guess there must be moisture coming in from outside.
the spray foam is great insulation and i highly recommend it, but the moisture will still be present.
in what climate are you? does this happen year round?

Mail me please
