Contractors tasked with retrofitting an older home with a radiant barrier system will often use a combination of radiant barrier products that may include aluminum foil pre-applied to both sides of a piece of rigid insulation or reinforced sheets of radiant barrier material that can be rolled out and draped between the roof rafters using staples.
In 2009, McDowell Owens performed a series of experiments with reinforced sheets of radiant barrier material to determine what would happen if a grounded radiant barrier became energized through contact with an exposed electrical conductor.[2] What they observed was that, as current began to flow through the radiant barrier material, intense heating occurred at the staples, followed by electrical arcing.[3] The heating and arcing immediately ignited the combustible substrate materials upon which the aluminum foil was mounted.
