My oh my ….. we have some folks with their knickers on fire.
I am taking care of a friend's home. I knew he wanted to install a radiant barrier while he was gone, so I placed a remote temperature sensor in his attic. Before the barrier was installed, it read, on average, about 129 deg F during the afternoon. After the radiant barrier was installed, the attic's average temp was 113 deg F during the afternoon. The heat load on the ceiling is significantly reduced.
