Radiant Barrier Decking In Attic

Radiant barrier decking in attic.

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. Increasing summer energy consumption and cooling costs. This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction. Foil backed osb is applied mostly in attics.

But on the bright side. Your radiant barrier makes the roof deck sheathing invisible from the attic. 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. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it.

The temperature of the attic space increases and that heat is transferred to the building below. When laying the foil insulation it is not. Starting at one end of your attic install our ultima foil breathable radiant barrier over across attic floor joists. It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat.

The radiant barrier is basically just directing the same amount of heat away from the attic and the attic insulation. 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. Product overview the osb techshield radiant barrier osb is engineered to improve energy efficiency.

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 installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. Radiant barriers are utilized to reduce summer heat gain in attics. The roof still is gaining and loosing heat.
