As we already mentioned this type of roof works primarily through the reflection of heat.
Radient barrier for roof.
When the sun heats a roof it s primarily the sun s radiant energy that makes the roof hot.
But on the bright side.
A radiant barrier roof is a type of roof that is designed to reflect heat.
A cooler attic space means less heat moving to the cooler space below the attic.
Benefits of radiant barrier sheathing when utilizing osb radiant barrier sheathing you can reflect up to 97 of solar radiation which translates into an.
If you ve ever wondered why some attics are lined with shiny metallic looking material this article will explain the ins and outs of the subject.
You are getting a new roof so why not scrape off the shingles put down roofing felt thenradiant barrier foil and thenshingles right on top.

This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.
In these attic space applications there is an air space below the radiant barrier.
Much of this heat travels by conduction through the roofing materials to the attic side of the roof.
The hotter it gets the better radiant barriers work.
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.
Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits.
Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f.
Florida solar energy center conducted a study on radiant barrier and shingle temperatures and found that the roof increased in temperature by only about 5 degrees at the hottest point of the day when the heat was entering and exiting the roof simultaneously.
