Roof Deck Radiant 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.

This can be roof shingles reflective chips roof sheathing etc. There are several types of roofs that have an air space between the roofing material and the roof deck.

In these attic space applications there is an air space below the radiant barrier. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. Increasing summer energy consumption and cooling costs. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.

A radiant barrier can be effective with an asphalt shingle roof only when installed inside the attic either to the underside of the roof decking or to the underside of the roof rafters.
