In with the good, out with the bad.
Radiant barriers are made of lightweight, highly reflective material that is installed on roof decks to maximize heating efficiency. By reflecting (rather than absorbing) radiant heat energy, the barriers help protect against summer heat gain and reduce winter heat loss. This means your HVAC system will run more efficiently, reducing energy usage and saving money. Not only do radiant barriers protect against moisture, air currents and vapors, but they also help protect against fungus, insects, and nesting rodents.
