Use a few staples to hold in place then install battens.
Radiant heat barrier metal roof.
How does it pay to add a radiant barrier with a new roof.
Increasing summer energy consumption and cooling costs.
Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction.
The temperature of the attic space increases and that heat is transferred to the building below.
Installing the radiant barrier foil under a metal roof is quick and easy.
Galvanized and galvalume metal roofs are hot roofs.
For new construction furring method.
Begin attaching the reflective insulation at the end purlin using double sided tape if necessary to hold the product in.

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.
Radiant barrier under shingles scams bad information foil under shingles will not create a radiant barrier unless there is an airspace on one side of the foil.

Begin unrolling the insulation pulling tight and continuing to mound the product to purlins.
Even on a bare metal roof when sunshield is used if it is 85 f outside then the surface temperature of the metal will be 85 f with sunshield rather than 160 f without sunshield.
It also prevents corrosion and surface deterioration.
