Radiant Barrier Decking In Attic

Foil backed osb is applied mostly in attics.

Radiant barrier decking in attic.

Starting at one end of your attic install our ultima foil breathable radiant barrier over across attic floor joists. The roof still is gaining and loosing heat. This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction. Your radiant barrier makes the roof deck sheathing invisible from the attic.

The radiant barrier is basically just directing the same amount of heat away from the attic and the attic insulation. 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 barriers are utilized to reduce summer heat gain in attics. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it.

It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. Product overview the osb techshield radiant barrier osb is engineered to improve energy efficiency. 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.

Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. The temperature of the attic space increases and that heat is transferred to the building below. 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.

But on the bright side. April 19 2019 posted in. 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. They don t however reduce heat conduction like thermal insulation materials.
