Why is the most insulation needed in ceilings or roofs? Just wanted to know
well insulation in general is to keep the inside temperature different than the outside. since hot air usually rises, i think it is to keep warm air form escaping in winter. also you don't usually have a heater in the attic, or air conditioning so insulation will keep the air in the attic from having an effect on the air within the house. that is my idea as to why
