ISO & XPS will only be in cavity, that can also serve as ventilation cavity receiving air from soffit to ridge
You're proper: a roof coating might help lessen attic temperatures.

Last of all, my h2o heater is usually within the attic, so one aspect result is almost no standby heat decline in the h2o heater towards the attic at 115 levels:)
Insulation performs. The way in which we evaluate the success of insulation is by comparing R-values. A layer of R-30 insulation is two times as powerful as being a layer of R-fifteen insulation; it will eventually only make it possible for half the heat move in the R-15 insulation.
