Radiant Barrier Decking In Attic

The roof still is gaining and loosing heat.

Radiant barrier decking in attic.

Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. However it is also used in wall systems. Increasing summer energy consumption and cooling costs. 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.

This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. Radiant barriers are utilized to reduce summer heat gain in attics. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. Starting at one end of your attic install our ultima foil breathable radiant barrier over across attic floor joists.

Foil backed osb is applied mostly in attics. 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. 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.

Your radiant barrier makes the roof deck sheathing invisible from the attic. 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. But on the bright side.

When laying the foil insulation it is not. 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. The radiant barrier is basically just directing the same amount of heat away from the attic and the attic insulation. The temperature of the attic space increases and that heat is transferred to the building below.
