Insulation doesn't simply make a building warmer inside, it keeps heat out just as well as it keeps heat in. If your apartment is too warm in the winter it is probably because you have too much sunlight coming through your windows, or because your downstairs neighbor lives in a sauna.
- makomk 6y agoKeeping heat out is of somewhat limited use unless you have air conditioning, because there are a whole bunch of sources of heat (people, appliances, solar gain through the windows, etc) that are enough to make the inside of a well-insulated and well-sealed building warmer than the outside. Also, a lot of non-US countries strongly discourage aircon on residential buildings for environmental reasons; I know the UK certainly does and Canada is probably similar.
