You’ve probably heard a lot about radiant barriers,
and how they can save you greatly on your energy bills. However, it might be
confusing to understand how exactly they work.
Heat flows in three ways: conduction, radiation and
convection, with the former two being the principal ways how heat flows into
the home. Conduction is the flow of heat by physical contact. Radiation is heat
in wave form that can be felt without actually needing to touch the source of
heat. This radiant heat travels at a very fast rate until it is either
reflected or absorbed.
Without a radiant barrier, your attic insulation can heat up
to 130 degrees, and when this happens, your ceiling will act as if it is that
temperature outside. To get comfortable, you’ll probably have to run the A/C at
full blast, and this causes you to use a great deal of energy to suck out the
heat.
A radiant barrier breaks the path to keep radiant heat from
entering into your home, reflecting 97% of the radiant energy. In short, the
radiant heat is back to where it came from, with no need to worry about the
roof temperature increasing, and studies have show roofs with radiant barriers
increase between only 2-10 degrees.
