@thegreengiant88@FenixAmmunition I think the point is that insulation plus A/C is a net positive in summer and that good insulation alone doesn't eliminate heat related casualties.
@thegreengiant88@FenixAmmunition That's why you leave the A/C on. Every object in the house retains the cool from the A/C and is more efficient than turning it on and off all the time. The insulation then does it's job of keeping the heat out.
