Trying to see the best and most cost efficient way to insulate this laundry room. The basement besides this is fully insulated (and finished) but this room gets cold. I’ve taken some pictures and described the direction and what they are looking at, and I am just tempted to find any and all gaps and holes (leading to other areas of the basement - near subfloor) and stuff insulation in. What about the back wall which is the cement foundation? Thanks for any and all help.
