Radiantguard radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by reflecting up to 97 of the radiant heat that strikes its surface thereby reducing heat transfer from the attic to living spaces resulting in lower utility bills.
How should reflective foil in the attic be installed.
Much of this heat travels by conduction through the roofing materials to the attic side of the roof.
When the sun heats a roof it s primarily the sun s radiant energy that makes the roof hot.
Access the attic and measure the floor space s length and width with measuring tape.
The first is stapling foil to the bottom of the roof rafters the second is laying it out over the existing attic ceiling insulation.
This method can be used in any climate though it historically has been most popular in colder climates.

To make it easy to eyeball how level the material is as you blow it in screw depth guides to joists throughout the space.
This method also reduces the heat subject to attic mounted ac duct work thereby allowing them to work more efficiently.
