Roof Plywood With Radiant Barrier

Radiant barrier plywood sheathing rigid strong ultra cool.

Roof plywood with radiant barrier. Basically plywood or osb sheathing with a thin aluminum facing on one side radiant barrier sheathing installs like any other roof sheathing. To combat this problem many builders in hot climates have made radiant barrier roof sheathing standard on their houses. So when the sun hits the roof and radiates into the attic or wall the foil layer of the osb sheathing reflects the heat to the roof or exterior wall which keeps the top layer of the insulation just a few degrees warmer than the outside air temperature. How traditional roof sheathing works.

Five problems with foil backed osb radiant barriers. Made from high quality osb sheathing these panels are built for stiffness and stability. More energy is needed to cool the house and that means higher energy costs for. With no barrier to restrict the heat it radiates through the insulation into living spaces causing room temperatures to rise.

You just have to keep the shiny side face down. Radiant energy transferred through standard roof sheathing creates heat build up in the attic. 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. Other kinds of radiant barriers combine reflective materials usually aluminium foil with materials like plastic films cardboard and kraft paper.

Radiant barrier sheathing made up of either plywood or oriented strand board osb with athin layer of aluminum facing on one side is installed to the roof rafters with the aluminumlayer facing down. Radiant barrier plywood can easily be made yourself by simply stapling our ultima foil directly to the osb or plywood decking during a new roof construction. Many building supply companies offer a plywood or osb oriented strand board sheathing product with a radiant barrier already laminated to one side of the board. In fact tests reveal that radiant barrier panels block up to 97 of the sun s radiant energy making the attic up to 30 cooler and reducing indoor hvac cooling costs by up to 17.

I find it curious that i have never seen radiant barrier sheathing installed on any house that i ve ever toured during the construction phase and that s a few hundred houses at the. The aluminum is not used for its reflective properties but for its low emittingproperties. This seems like such a simple solution to reduce energy consumption. The foil layer of the osb lowers.

Structural radiant barrier roof sheathing panels help keep structural radiant barrier roof sheathing panels help keep your attic cool and save on cooling energy consumption during hot summer months.
