About Radiant Barriers

According to the U.S. Department of Energy, residential radiant barriers help homeowners lower air conditioning costs and lessen the impact of summer heat.

To create a radiant barrier, pros install metal foil over the rafters in an attic and reflect the sun’s heat away from the home. This is most effective when coupled with reflective insulation. To maximize cooling efficiency, the system must include an air gap between the reflective surface and the interior of the roof.

Radiant Barrier vs. Reflective Insulation

Reflective insulation is insulating material (like batt and roll insulation) that has at least one reflective surface. Radiant barriers do not have insulating material attached, but you can install them over new or existing insulation to maximize the efficiency of both materials.

How Much Does Radiant Barrier Save?

Homeowners in hot climates can save as much as 10 percent on their heating bills, or about $120 off per year. Cooler climates typically save $15 per year on average with a radiant barrier upgrade. If homeowners upgrade to R19 insulation, they can save from $180 to $300 on heating bills.

DIY vs. Hiring Radiant Barrier Installer

Radiant barrier won’t work at peak capacity if it’s incorrectly installed. The U.S. Department of Energy recommends homeowners hire a radiant barrier installer to make sure the job gets done right. However, it is possible to DIY install this insulation with care. Installers can staple radiant barriers up on their own or lay the material over existing insulation.
