A radiant barrier (materials
usually consisting of a thin sheet or coating of a highly reflective
material) reflects up to 97% of the “radiant”
energy which comes from the sun. Radiant energy is generated by
the sun and travels through space and does not create any heat
until it strikes an object. This energy would normally conduct
through your roof, radiate to your insulation and then into your
home. By applying Radiant Barriers to the underside of your roof
deck, you can lower your utility bills and increase your comfort.t

A good example of “radiant energy” is when you stand
in the sun on a hot day, the air temperature is essentially the
same in the sun and the shade however, you are a lot hotter in
the sun. The shade tree is blocking the radiant energy, making
you more comfortable. We are the bes
FACTS:
- Heat only flows when there is a difference in temperature and
it always
flows from the higher temperature to the lower temperature level.
(Heat loss in winter, heat gain in summer)
- If you have a 2 story home with one air conditioning unit, the
result can be dramatic.
- If you work in your garage and do not air condition it, you
can enjoy up to approximately 20 degree lower temperatures during
the day by adding Radiant Barriers.
INSTALLATION METHODS
Radiant barriers are materials that are installed
in buildings to reduce summer heat gain and winter heat loss, and
hence to reduce building heating and cooling energy usage. The potential
benefit of attic radiant barriers is primarily in reducing air-conditioning
cooling loads in warm or hot climates.
Radiant barriers usually consist of a thin sheet or
coating of a highly reflective material, usually aluminum, applied
to one or both sides of a number of substrate materials. These substrates
include kraft paper, plastic films, cardboard, plywood sheathing,
and air infiltration barrier material. Some products are fiber reinforced
to increase the durability and ease of handling. Radiant barriers
can be used in residential, commercial, and industrial buildings.
We exclusively use the HeatBloc-75 radiant barrier.
HeatBloc-75 radiant barrier coating is a water-based,
low emissivity (low-e) product and an excellent replacement for
foil or metallized plastic film radiant barriers. In many situations,
HeatBloc-75 is the only economical way to retrofit a radiant barrier
since it may be safely applied in enclosed areas at a low cost.
