Hi, im starting to plan to finish my basement. Could someone tell me the proper way to insulate? ive got block foundation, rigid insulation then frame against that ? vapor barrier , frame , them insulate with batts? , no vapor barrier ? 3/4 of basement walls are below grade, with the rear above grade with a walkout door. been in home a year and a half with no water or moisture problems. thanks , chuck
The building science foundation has the latest recommendations. I will be going the XPS aginst wall, no vapor barrier or batts route myself. Of course geographical location and moisture issues should be taken into account.
