Radiant Barrier Decking In Attic

Starting at one end of your attic install our ultima foil breathable radiant barrier over across attic floor joists.

Radiant barrier decking in attic.

This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. 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. Radiant barriers are utilized to reduce summer heat gain in attics. Increasing summer energy consumption and cooling costs.

The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it. 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. But on the bright side. The temperature of the attic space increases and that heat is transferred to the building below.

Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. The radiant barrier is basically just directing the same amount of heat away from the attic and the attic insulation. It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat. Continue covering the attic floor by overlapping each section of radiant barrier already rolled out by 2 inches.

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. When laying the foil insulation it is not. 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.
