The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it.
Roof radiant barrier insulation.

Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits.
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.
The most effective radiant barrier sheathing is a structural roof sheathing panel which consists of an osb panel with heat reflecting foil laminated to one side.
Radiant barrier foil insulation systems block radiant heat energy instead of absorbing it like fiberglass insulation.
The list of uses includes crawl space radiant floor attic and walls.
Other kinds of radiant barriers combine reflective materials usually aluminium foil with materials like plastic films cardboard and kraft paper.
A radiant barrier is designed to increase the effectiveness of your thermal envelope.

But on the bright side.
This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.
Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f.
Your radiant barrier makes the roof deck sheathing invisible from the attic.
