It is meant to supplement insulation not replace it.
Radiant barrier roof decking and insulation.
Myths busted and facts explained.
By reducing the amount of radiant heat reaching the insulation in your attic the insulation remains cooler and is able to keep your home more comfortable.
This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.
Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f.
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.
A radiant barrier is designed to increase the effectiveness of your thermal envelope.
Unlike insulation like fiberglass or foam neither radiant barriers nor the roofing materials hold radiant heat.
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 should be installed in a manner to minimize dust accumulation on the reflective surface.
Radiant barrier under metal and tile roofs the radiant barrier acts as your first line of defense against radiant heat and the foam closed attic acts as the second line of defense against conductive heat flow.
Starting at one end of your attic install our ultima foil breathable radiant barrier over across attic floor joists plywood decking or existing insulation.
The radiant barrier reflects 95 of the radiant heat back to the roofing materials which then emits over 90 of the heat out the roof almost instantly.
This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction.
Dust accumulation on the reflective surface will reduce its reflective capability.
Your radiant barrier makes the roof deck sheathing invisible from the attic.
Radiant barriers and reflective insulation systems work by reducing radiant heat gain.
Use a stick 1 4 furring strip with nail in the end works well to help push the barrier into the tight spaces of your attic.
But on the bright side.
It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat.
The osb techshield radiant barrier osb is engineered to improve energy efficiency.
