Radiant Barrier For Roof Decking

Suitable applications include sheathing in walls flooring and roof decking.

Radiant barrier for roof decking.

Your radiant barrier makes the roof deck sheathing invisible from the attic. Installing radiant barrier under the roof decking is the preferred method versus on top of the insulation because it gives an air gap for the heat to escape to the ridge vent without creating a potential moisture problem between the radiant barrier and the attic floor. 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. Radiant barrier should always be installed to work with the soffit and ridge.

It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. April 19 2019 posted in. But on the bright side.

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. 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. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. Radiant barriers are utilized to reduce summer heat gain in attics.

In these attic space applications there is an air space below the radiant barrier. Increasing summer energy consumption and cooling costs.
