        rigid insulation Sign In/Join 
        posted
        While taking care of other can of worms(rim joist problem), thought I might as well open another.Insulation???? in basement
        Present plan is to cover walls with rigid (xps) then tape and seal all joints and then frame directly in front of that. I will add Roxul between studs and probably soundproof ceiling with something also.
        Question is 1 inch at R5 or 2 inch at R10 for foam board (vapor barrier/retarder?) then I will add the amount Roxul (thickness) accordingly. My good friend in Maine said its always better to insulate plenty, within reason (go past minimum code) since the cost of heating or air conditioning does not appear to be getting cheaper.
        As for heating I'm leaning toward radiant and going with tile (a few tile people have allayed my fears about errant cue ball doing damage) I'm still not completely sure but I do like the fact that tile will support heavy table and stand up to any water mishaps.

        Go here and do some research on the subject. http://www.buildingscience.com...work/dtw-house-plans

        Thanks Sparky, I have checked this out before and from the diagram's there it looks like Roxul would fall in under the unfaced cavity insulation rule, and the gasket for capillary-break/thermal-break would be the standard foam sill gasket material.
        Now if I just had the foam under the concrete slab..... Let me think??? break up slab,lay the foam,pour new slab $$$$$$...wife buries me under it.

        You could lay sleepers, rigid foam, ply and continue with your flooring. Just a thought. But if you have doorways you would have to adjust for the added heigth.

        After review of Building Science website,.. it looks 2 inch foam is best first layer,..plus my recent discussion about insulation with Maine relatives on this topic and his philosophy was that energy cost are not going down so it never will hurt to insulate better, though it will hurt the people your paying whatever energy for heat and air your using.
