$78 off Enerflex 16 in. Radiant Barrier (50-Box)

Enerflex, a highly reflective, double-sided, multilayered material, blocks up to 96% of radiant energy and can be installed in new and existing homes. It installs between rafters to the underside of a roof and on other vertical surfaces in an attic to reduce solar heat gain into the home. It also reduces heat transfer by thermal radiation across the air space between the roof and attic floor, keeping an attic up to 30 degrees cooler. In cool weather, Enerflex helps prevent radiant energy from leaving the home and reduces heat loss, which adds up to significant energy cost savings.
