basement insulation


Hi. I'm looking to insulated my basement walls. Have been researching on line the best way of going about it. I don't want to take much space away from the basement so i will stay with the fir strips on the concrete wall which is there already. My question is i will replace the fir strips with new ones, but with all the info on the net it states that you should use pressure treated fir strip to avoid mold as wood absorbs the moisture from the wall. Should I use the pressure treated fir strip or use the 1 1/2 pink foam board with grooves for the fir strip or place a thin layer of insulation behind the fir strips before nailing to wall and rigid foam between the fir strips. To much information overload. thank you for any help/suggestions.

XPS on the walls, then use 2x4 studs for the walls, with pressure treated 2x4 for the bottom plate. You never want the wood in direct contact with the concrete wall. Buildingscience.com has all of this info.

Maybe something bad, maybe something good. I guess we'll never know, 'cause you're going to guard it. You won't touch it, will you?

Use p.t. furring, with an application of water-proofing on 6 sides as the flats will be in full contact with the wet foamboard.
