Radiant Barrier Savings

Attic Savings:

It is generally accepted by the DOE that installing radiant barrier in the attic will reduce heat gain through the ceiling by 40% typically leading up to a 17% reduction on heating and cooling utility bills.  In the summer it blocks most of the radiant heat from penetrating insulation and heating up your house.  In the winter it will helps to hold heat in your house by not allowing it to radiate off the insulation to the cold attic air.

Several of our costumers have taken the time to compare electric usage, weather data, and calculate savings after installing ARMA FOIL™.  They have reported savings from 12% up to 39% on energy usage.

Light Box Test:

This simple demonstration helps to show the effect that ARMA FOIL™ radiant barrier has when applied to the outside of the regular insulation.  Both sides have R-30 fiberglass insulation with 75 Watt lamps shining on them.  The left side of the box has a single sheet of ARMA FOIL™ radiant barrier laid on top of the insulation.  You can see how much radiant heat has been blocked by the thermometers on each side.  The right side without ARMA FOIL™ reads a temperature of 152.6°F, while the side with ARMA FOIL™ only reads 90.9°F.

We are in the process of implimenting a temperature data collection system in a residential home.  You can see some preliminary results here.
