You should insulate buildings because buildings sometimes lose a ton of heat and you can a lot of money. We shouldn’t always have insulation in some certain types of buildings because the buildings could have lots of gaps holes cracks and more and the heat will come out and you’ll be really cold especially in the winter! We shouldn’t have insulation in YIS because most things are outdoor and when you open the door the heat will go outside and again, we will lose a lot of money. I think that we should not insulate buildings because some buildings have opened rooftops and i’m not kidding I really mean it, but anyway the heat and energy can go outside. I think that insulation is important because you can get a comfortable house, school, or building using the least amount of energy and having something efficient in the building. Thermal insulation in buildings is an important factor to achieving thermal comfort for its occupants. How much insulation a house should have depends on building design, climate, energy costs, budget, and personal preference. To determine whether you should add insulation, you first need to find out how much insulation you already have in your home and where. Insulating buildings during construction is much easier than retrofitting, as generally the insulation is hidden.
