Underneath roofing materials or in the attic this keeps the attic airspace cooler during the summer.
Roof radiant heat barrier.
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.
Benefits of radiant barrier roof underlayment.

Radiant barriers are utilized to reduce summer heat gain in attics.
Radiant barrier foil insulation systems block radiant heat energy instead of absorbing it like fiberglass insulation.
Increasing summer energy consumption and cooling costs.
But on the bright side.
Roofs with radiant barrier have the potential to lower the temp at night because the radiant barrier prevented the heat loss that would typically occur from the traditional mass insulation on the attic floor rising to heat the roof.
This means radiant barrier can increase the life of the roof shingles.
The list of uses includes crawl space radiant floor attic and walls.
A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.
Our product is easy to handle and install.
The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor.
The heat that would normally be absorbed by the insulation is now being bounced back to the roof deck and causing the roof to emit more heat upward rather than both upward and downward.
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.
A radiant barrier works best when it is perpendicular to the radiant energy striking it.
Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits.
This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.
The temperature of the attic space increases and that heat is transferred to the building below.
This in turn prevents your house from heating up as much during the colder months this material will help prevent your home s heating from escaping through the attic and out the roof.
Your radiant barrier makes the roof deck sheathing invisible from the attic.
