Insulating basement cinder block wall
My name is Mike and I am currently planning to finish my basement in Michigan. My basement walls are hollow cinder block and I plan to paint the with drylock or a Ames block and wall liquid rubber paint (not sure which yet) to prevent moisture from seeping to the interior. Following this, I plan on putting 2in of rigid foam insulation (eps) on the basement wall followed by the studs. I plan on keeping the space between the studs as air space in front of the rigid foam for electrical and plumbing. I was told by my contractor that it’s best not to insulate the basement wall to allow the cinder block to dry to the inside. He said that if I put rigid foam insulation it won’t allow the cinderblock to dry and may result in a mold issue. Most of what I have read said to use rigid foam insulation.
I have read most of the articles regarding insulating basements on this forum but would like some additional advice regarding this specific issue.. Can you please shed some light on if using a drylock type sealer of the cinder block followed by 2in of foam would cause a mold issue or if even rigid foam on exposed cinder block would cause a mold issue?
In addition to that, I have read that adding rigid foam insulation to cinderblock wall could cause the cinderblock to freeze in the winter cause cracks in foundation. Is this true?
Thanks in advance.
