Roof Decking That Is Radiant Heat Reflective

Structurally rated panel with reflective insulation and high mechanical properties.

Roof decking that is radiant heat reflective.

The bottom of the roof deck will be 20 or 30 degrees lower. 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 should be installed in a manner to minimize dust accumulation on the reflective surface. The thermal envelope is usually your walls and ceiling.

Unlike insulation like fiberglass or foam neither radiant barriers nor the roofing materials hold radiant heat. Suitable applications include sheathing in walls flooring and roof decking. Your radiant barrier makes the roof deck sheathing invisible from the attic. When the sun heats a roof it s primarily the sun s radiant energy that makes the roof hot.

Since radiant heat is in a waveform it can be reflected. Through the process of infrared radiation the heat from the roof is emitted or radiated into the attic where the insulation absorbs it. 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. Ideal for construction and other uses.

The problem with putting any r value on a roof is that the roof is normally not really part of the thermal envelope. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. Other kinds of radiant barriers combine reflective materials usually aluminium foil with materials like plastic films cardboard and kraft paper. The roof just keeps it dry.

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. 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. Reduces temperatures by up to 30 degrees fahrenheit.

But on the bright side. Reduces up to 97 of radiant heat. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits.
