radiant insulation is very good for diflecting infra-red energy.
but how does radiant insulation compare to bulk fiberglass insulation,
against ALL OTHER forms of energy ??
electromagnetic pollution from powerlines ?
noise energy ?
do radiant barriers diflect those well, too ?
even though they are different types of energy ?
the answer to these questions, are not readily apperant on google.
because our school systems, do not train children to consider basic questions.
and now those children are grown up, and selling insulation.......
