Radiant Barrier Decking In Attic

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 barrier decking in attic.

Product overview the osb techshield radiant barrier osb is engineered to improve energy efficiency. This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction. They don t however reduce heat conduction like thermal insulation materials. Oriented strand board osb with a thin layer of low emitting aluminum foil attached to one side is a common type of thermal radiant barrier sheathing.

However it is also used in wall systems. To understand this better consider a room with one light source in the form of an unshaded light bulb hanging in the middle of the room. Increasing summer energy consumption and cooling costs. Starting at one end of your attic install our ultima foil breathable radiant barrier over across attic floor joists.

Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. Your radiant barrier makes the roof deck sheathing invisible from the attic. Continue covering the attic floor by overlapping each section of radiant barrier already rolled out by 2 inches. April 19 2019 posted in.

The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat. Radiant barriers are utilized to reduce summer heat gain in attics.

The roof still is gaining and loosing heat. Foil backed osb is applied mostly in attics. When laying the foil insulation it is not. 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.
