Your radiant barrier makes the roof deck sheathing invisible from the attic.
Radiant barrier roof panels.
Other kinds of radiant barriers combine reflective materials usually aluminium foil with materials like plastic films cardboard and kraft paper.
Radiant barrier foil insulation systems block radiant heat energy instead of absorbing it like fiberglass insulation.
This means radiant barrier can increase the life of the roof shingles.

As the original 1 brand of radiant barrier sheathing lp techshield panels vaporvents technology prevents moisture buildup during and after construction while blocking up to 97 of radiant heat in roof panels.
Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f.

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.
Radiant barrier sheathing panels are engineered wood panels with a thin layer of highly reflective aluminum facing that reduces radiant heat gain into the attic.
Some products are fiber reinforced to increase durability and ease of handling.
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.
Installing a radiant barrier underneath the roof will cause the roof temperature to increase by a few degrees usually 2 10º.
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.

This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.

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.
