A Guide On How to Install Radiant Barrier Foil Insulation

Most of the heat that gets into a home comes through the roof. Radiant barrier foil insulation fitting in an attic can decrease attic temperatures by almost 30 degrees when stapled with a staple gun to the underside of roof rafters. It bounces back up to 97% of the radiant heat that strikes its surface. It decreases heat transfer from the attic to living spaces resulting in lesser utility bills. This method also cuts down the heat subject to attic mounted AC ductwork allowing them to work more effectively. However, the concern in many people remains how to install radiant barrier effectively.

Typically, you can easily lay a blanket of radiant barrier over the ductwork to shield them from the heat.
