When installed properly radiant barriers can reflect up to 95 of the radiant heat off the attic. Radiant barrier is a home insulation type that is focused on reducing summer heat gain.

The best way i have seen to describe this effect is it s like putting your home or office under a shade tree. Unlike traditional thick layers of insulation radiant barrier is a thin reflective material.
