Reflective radiant barrier installation on attic rafters to block up to 97% of radiant heat transfer. Reduces attic temperatures by 20-30°F in Alabama summers, significantly lowering cooling costs.
Yes. In Alabama's hot Alabama summers, radiant barrier can reduce attic temperatures by 20-30°F and cut cooling costs by 5-15%. It's most effective in southern climates like Alabama where cooling is the primary energy expense.
No — radiant barrier must face an air space to work. We install it on the underside of roof rafters in Alabama homes, not on top of insulation. Laying it on insulation traps moisture and voids the benefit.
