What is a reflective radiant barrier?
Radiant barriers are achieved by using reflective foil insulation. And unlike other insulation materials, radiant barriers reflect radiant heat energy instead of absorbing it. Testing data shows that in the hot summer months, up to 93% of heat gain is absorbed by radiant heat energy. In the winter months, 65-80% of heat loss through side walls is due to radiant heat loss. Using reflective foil radiant barrier insulation is the only way to help stop the loss or gain of radiant heat energy.
