Sorry if this is posted in the wrong forum.
I am planning on how to spend my summer. Since most of the insulation in my crawl space was installed upside down and is damp because of water problems, I am planning to re-insulate. I was wondering if I could install closed cell foam board instead of fiberglass. If so, how would be the best way to keep it in place between the floor joists. Would something like Liquid nails do the job? If so and I need to add an additional sheet or two, again, would it be O.K. to glue them together?
Do you recommend one brand over another?
P.S. I am working on the mositure problems and plan to replace the Poly that is on the ground with new, and make sure it is overlapped and sealed.
Thanks in advance for any input.
One more thing. I am going to remove all the vents and seal them up with hydraulic cement, as a couple of them are actually below ground level…
