As you may recall i am renovated a 1.5 story house soon. I am confused about insulation 1) The basement ceiling. What i gather 6" of lose insulation is a good idea. I am thinking it is a problem to cover pipes and electrical work? Maybe cover it with small pieces that just cover each joicey space so they can be taken off in the future. I heard you should caulk under neath there as much as possible or does it matter? Would a layer of Styrofoam board be simpler? 2) The ceiling on the main floor (the floor in the attic) People keep telling me not both insulating this but it seem like a good idea since i will spend most of my time on the main floor so why lose the heat to upstairs. Also i am not so sure how insulated the roof is. So how much a difference will it be insulating the basement and ceilings?
