      Yes. Insulation helps in both hot and cold environments. I live in a desert where it routinely hovers around 100F for three months out of the year. If my house weren’t insulated I’d bake. As it is, I don’t need an air conditioner, I do fine with just a fan, and letting the house cool off at night. The house stays around 80F for most of the day, until the late afternoon.
