This is the one area of insulation where we offer absolutely no options. We install closed cell spray foam and nothing else!! The reason for this is because nothing else should be installed here…EVER.
No one says it better when it comes to insulating your basement than Mike Holmes so this entire section is taken from his publications.
“no matter what, if you insulate your basement the same way you do an above-grade wall — using wood studs against the wall, with batt insulation in between and vapour barrier over that — you will have air movement and problems with condensation, and very likely, with mould” – Mike Holmes, excerpt from The Globe and Mail October 5, 2007
