Is there value to radiant sheathing on South/West-facing walls in hot climate?
Is there any measurable benefit to installing radiant barrier sheathing panels (7/16″ OSB) on vertical walls with a West or South exposure in a Southeastern climate? Of particular concern is the siding material ( 1/2″ thick fiber cement shakes) which will seemingly act as an unintended heat storage device, continuing to radiate heat into the wall assembly long after sunset.
