What is a Radiant Barrier?
Radiant Barriers are aluminum foil reflective materials that are
installed in residential or commercial roofs to increase energy
efficiency by reducing solar heat gain. This reduces the radiant
heat gain to ducts and insulation located below the radiant
Installing a radiant barrier "tent" in an attic
space deflects radiated heat from the roof. It blocks the roofs heat
from radiating to the ceiling below. See RB Applications
How it works.
energy from the sun penetrates your roof and builds up heat in you
attic. Shingles, insulation and conventional roof sheathing don't
stand a chance against this intense heat transfer. In the summer,
attics can reach temperatures of 150-170 degrees and transmit that heat
into you home.
makes your home uncomfortably warm and causes your air conditioning to
work harder and longer to achieve the desired comfort.
Radiant Barriers's unique pure aluminum foil sheet prevents 97% of the
summer radiant heat from entering your attic, reducing attic
temperatures up to 50 degrees. Living areas and air conditioning
ductwork stay cooler so less energy is required to maintain
comfort. As solar heat increases, radiant barriers effectiveness
