I was wondering what the pros and cons are to putting insulation on the ceiling of a basement. The reason for my asking is someone has told me that it isn't wise because cold air doesn't rise anyways(I already knew that) and you would cut any heat off coming from the boiler and water heater that might warm up the kitchen floor up above. I was going to do this because the kitchen floor is very cold when the temp outside gets cold. There are drafts that seem to be in the corner of the kitchen where the insulation is lacking in the basement. I am not sure if that is wher eit is coming from but I thought it wouldn't hurt. Any thoughts or suggestions?
