Radiant Barrier For Roof Decking

Your radiant barrier makes the roof deck sheathing invisible from the attic.

Radiant barrier for roof decking.

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. Increasing summer energy consumption and cooling costs. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat.

Radiant barrier should always be installed to work with the soffit and ridge. 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. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.

Radiant barriers are utilized to reduce summer heat gain in attics. April 19 2019 posted in. Suitable applications include sheathing in walls flooring and roof decking. 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.

The osb techshield radiant barrier osb is engineered to improve energy efficiency. Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f.
