I have these solid insulation leftover panels and I am planning to reuse them to insulate the garage or a shed. It is going to happen in spring but till then they are in my way. As I am re-organizing the garage (for now it is literarily storage and small Woodworking area) I am looking for an area to store these and I just realized that for this winter I could just put them against the exterior walls of the garage, on the inside (this is an attached garage)
The space is not heated right now and I might install a vented/unvented heater very soon as I need to do some woodworking there The walls are cinder block with brick veneer on the outside and some very old plaster coating on the inside (no framing at all)
Is this a good or a bad idea?
The only downside I am seeing is that humidity might accumulate there ...condense maybe ? They will not be like very tight against the wall It is not a lot of insulation just what you see in the picture
