Question one. How far down? I live in a comfortable 60-year-old house with an undeveloped basement used mainly for storage. I don’t intend to develop it, but I’d definitely like to put a little insulation in place around the inside of the foundation in order to save some energy. (We don’t explicitly heat our basement, but enough heat escapes from the ducting, hot water heater, etc., to make it tolerable down there in the winter.) The basement has 7.5 foot painted (latex) concrete walls (in excellent condition) that rise about three feet above ground level, with the floor joists embedded in the concrete at the top. I haven’t yet determined how far down I should take the insulation. I’ve been looking around this forum, but haven’t yet found an answer to this question (for an undeveloped, unheated basement.) Any suggestions? (I suspect it’s good to not insulate it all the way down, so as to get the benefit of some cooling in the summer. ) Question Two. What’s wrong with this solution? The southern Alberta climate is pretty dry, summer and winter, and I’ve never had any sign of moisture in my basement (except when my hot water heater leaked on me). Luckily, we have sandy soil and excellent drainage. Anyway, I want to do the insulation as simply as possible and suitable for a basement that will only be used for storage. (I’d like to do a neat job, however.) . . . . . Well, here’s my plan. I’m going to buy some rigid R5 pink foam board and use silicon or some such thing to glue it to the walls from the top down to the desired depth (see question one). Then I’d like to glue some painted 1/8” thick (?) wood paneling over it to provide a protective surface. I’ll cover the joints with 3/4” molding. I don’t plan to use a vapor barrier because our climate is so dry and we’ve never had a problem with moisture. In fact, we’d welcome a little more moisture in our house, especially in the winter. So how does this sound? Any suggestions as to what type of adhesive I should use, if I go ahead with this? It may be evident from the preceding that I’m not really too experienced with home improvement projects, so any advice to steer me in the right direction would be very welcome. Thanks in advance.

I am framing a basement wall to the underside of a steel beam. Can I use some adhesive to adhere my top plate to the bottom of the beam? I am assuming that a mechanical fastener is out of the question.
