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.

Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. Foil backed osb is applied mostly in attics. The roof still is gaining and loosing heat. The radiant barrier is basically just directing the same amount of heat away from the attic and the attic insulation.

When laying the foil insulation it is not. But on the bright side. Your radiant barrier makes the roof deck sheathing invisible from the attic. They don t however reduce heat conduction like thermal insulation materials.

The temperature of the attic space increases and that heat is transferred to the building below. 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. 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. 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. This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction. Increasing summer energy consumption and cooling costs. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it.

Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. Continue covering the attic floor by overlapping each section of radiant barrier already rolled out by 2 inches.
