Roof Decking That Is Radiant Heat Reflective

The problem with putting any r value on a roof is that the roof is normally not really part of the thermal envelope.

Roof decking that is radiant heat reflective.

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. Much of this heat travels by conduction through the roofing materials to the attic side of the roof. The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface. Your radiant barrier makes the roof deck sheathing invisible from the attic.

But on the bright side. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. Reduces up to 97 of radiant heat. As an added plus weyerhaeuser rbs can even help keep non air conditioned uninsulated rooms like garages workshops and porches cooler increasing a home s usable space.

The radiant barrier reflects 95 of the radiant heat back to the roofing materials which then emits over 90 of the heat out the roof almost instantly. Other kinds of radiant barriers combine reflective materials usually aluminium foil with materials like plastic films cardboard and kraft paper. Ideal for construction and other uses. Rbs radiant barrier sheathing weyerhaeuser radiant barrier sheathing rbs comes pre fabricated with a reflective foil layer that reflects up to 97 of the sun s radiant energy minimizing heat transfer through the roof and insulation to interior living spaces.

Unlike insulation like fiberglass or foam neither radiant barriers nor the roofing materials hold radiant heat. Since radiant heat is in a waveform it can be reflected. The thermal envelope is usually your walls and ceiling. 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.

During the hot summer the heat of the sun can raise the temperature of the top shingles of the roof to nearly 180 degrees. Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f. The bottom of the roof deck will be 20 or 30 degrees lower. When the sun heats a roof it s primarily the sun s radiant energy that makes the roof hot.

Through the process of infrared radiation the heat from the roof is emitted or radiated into the attic where the insulation absorbs it. Suitable applications include sheathing in walls flooring and roof decking. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits.
