The hotter it gets the better radiant barriers work.
Attic radiant heat barrier.
Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs.
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.
Radiant barrier is a home insulation type that is focused on reducing summer heat gain.
When installed properly radiant barriers can reflect up to 95 of the radiant heat off the attic.
The best way i have seen to describe this effect is it s like putting your home or office under a shade tree.
They don t however reduce heat conduction like thermal insulation materials.

A cooler attic space means less heat moving to the cooler space below the attic.
Radiant barriers are made of aluminum and designed to reflect radiant heat from the sun.
It is meant to supplement insulation not replace it.
