Installing in an attic space

Radiant barriers are most commonly installed in an attic space stapled to the underside of the roof rafters or directly to the underside of the roof decking.

While they can be installed over the attic floor, care must be taken to make sure the attic space has adequate air flow to avoid condensation build up under the radiant barrier on the floor.
