Insulation doesn't prevent freezing, it just slows it down. If there is enough heat to not freeze by the time you drive it again, fine, it helped. Leave it long enough in the cold and it won't matter, it will all come to ambient temperature. But realize that insulation also slows down the heating process when you have under hood heat available after you start it.
