What is radiant barrier insulation? Radiant barrier insulation is a highly reflective material – usually a reflective foil – that reflects heat and reduces the amount of heat gain in your home, thus reducing your heating and cooling costs.

How does radiant barrier work? Radiant barrier works by reducing the amount of heat that enters your home through the attic. They reduce the amount of radiant heat that transfers to the underside of the roof. Radiant barriers are usually installed with an attic fan to get rid of the remaining heat left in the attic space.

How Much Money Can Radiant Barrier Save? Studies show that installing radiant barrier in your home can reduce your cooling costs by an average of 15% – especially when used in warm climates like Arizona.
