A radiant barrier commonly refers to a thin layer of aluminum film used to prevent radiant heat transfer between a surface that radiates heat (for instance, roof) and the surface that absorbs the heat (such as, attic floor insulation).
A radiant barrier is an energy saving product as it ensures that insulation do not absorb much heat released by the roof and enable you to save money when it comes to cooling costs in the summer. Those who run air conditioner continually will really benefit from the radiant barrier in the form of reduced electricity bill.
