Hello everyone, longtime lurker, lots of great info on here!
Getting ready to redo the basement, was a mold farm previously with wood studs in contact with block wall and fiberglass insulation bats with vapor barrier on the walls. The floor had plastic vapor barrier and 2x2 sleepers then particle board sub floor then peel and stick tiles.Then add some ground water from the floor to block seam = stinky mess.
Basement gutted to block walls & bare concrete floor, drainage corrected, interior walls painted with drylock to a course above grade, only about 6~8 courses of 12 courses below grade. Upstate NY in zone five close to the border of zone 6.
My plans after reading almost all the threads on this subject in here is:
2" foam on floors and walls sealed on seams, with foam.
23/32 t&g osb subfloor with engineered hardwood floors,tile in the full bath
2x4 studded exterior walls with unfaced roxul or denim,then 1/2" sheetrock, then paint
Spray foam band joist area with spray foam sealed to top plate of new walls,then fill with roxul
My questions are:
Do I need a plastic vapor barrier under the foam in floor and behind foam under the grade with EPS foam?
I can find 250 xps foam cheaper than 2lb eps foam for the floors? Using 1lb eps on the walls, the company that i found recommended 2lb eps for the floor. Would the 250 xps on the floor require the plastic vapor barrier if I went that way?
Sound good so far?
Thanks in advance
