I am finishing a basement with a 4 foot concrete wall with a wood framed and insulated wall on top. I am wondering the best way to insulate this, and if vapour barrier is needed. The top section is insulated with batt insulation and poly vapour barrier on the warm (inside) of the insulation. I am in canada where it gets very cold in winter and quite warm in summer. This is my idea. I will line the bottom part with a thin eps rigid foam, then frame with 2x4 in front of that. Creating a ledge around the basement. Then put batt insulation in between studs. Then vapour barrier tied into the poly above and then sheet rock both bottom and top part of wall. Does this sound like it will work? Thanks in advance for any advice.
