Basement Insulation (I can't use XPS)
I live in upstate NY and have a unique basement insulation. I am going to be finishing the basement. I have read the building science websites about the best way is to use XPS against the foundation wall then build your framed wall in front, but I have had to have the foundation repaired from a local foundation company (the wall had a horizontal crack from some grading/water issues from a terrible gutter design that has since been addressed).
Well the foundation repaired consisted of a number of carbon fiber strips and wall anchors. Not only to these make attaching XPS to the wall extremely difficult, I do not want to cover the wall up because I am certain when I sell my house in the future the buyer is going to want to inspect the repair and ensure the foundation is in good repair (due to the design I can put a couple access panels in the closets to see the foundation wall).
I have an interior weeping system which consists of a one inch gap between the basement wall and floor slab and the previous owners had someone drill weeping holes through the bottom of the basement cement block to direct any water into the weeping tile (since fixing the gutters I have never seen a drop of water in the basement). I have drylocked the wall.
What is the best way to insulate without using XPS? I have seen using poly is now frowned upon. Should I use paper faced fiberglass or something like an unfaced Roxul? Would it be worth putting just a small piece of (say 2 foot) XPS along the wall on the bottom to prevent any moisture from the holes that were drilled in the block from escaping? I appreciate any help!
