Last year I decided to let my brother-in-law finish my basement. After he finished the framing he moved away. Now I have wood framing complete and nothing else. He claimed he knew what he was doing, but after doing a lot of research I am finding that he may have been premature putting up the framing. I've decided I'm going to finish the job myself but I have a few questions.
The previous owner put in a new basement about 20 years ago with metal support framing and all. The foundation walls are block and covered with a few coats of Drylock. In the 15 years I have lived there I have never seen water.
I'm starting to think foam insulation should have been put up on the inside of the foundation walls; between the framing and foundation. I should be able to sneak the insulation in there since my brother did leave an inch of space. Should I do this? Is there any special type of insulation and/or adhesive I should use?
Am I right in thinking Foundation Wall->Foam Insulation->Gap->Framing->Sheet Rock? Should I use moisture resistant sheet rock? IS any other type of insulation necessary in there? Is plastic vapor barrier necessary?
My brother-in-law also used green treated lumber where ever the framing touches floor. Will that be sufficient against moisture?
Thanks for your help!!
