Why Consider Radiant Barrier?
Radiant Barrier is an insulation material that reflects heat entering or leaving a home, building, shipping container, apparel or packaging. Heat gravitates toward cold, but instead of absorbing heat and delaying this process like traditional foam or fiberglass, Radiant Barrier reflects heat back to its source
Radiant Barrier's effectiveness is not measured by R-value like traditional insulation. R-value measures how long it takes heat to transfer through a material or insulation. Radiant Barrier's effectiveness is measured by reflectivity. Radiant Barrier reflects 95 to 97 percent of the radiant heat back to its source.
We supply three products that incorporate radiant barrier:
• Super R® - a thin sheet Radiant Barrier reflective insulation, recommended for attic and house wrap applications. Ag-Barrier®, Deck Barrier®, and RF Shielding are variations of Super R®.
• Tempshield® - a Reflective "Bubble" Insulation Radiant Barrier recommended for metal buildings, walls, basements, crawl spaces, and packaging.
• Temptrol® - a metalized cloth Radiant Barrier reflective insulation fabric designed for clothing, curtains, and tents.
With over 35 years of experience, our technical experts can recommend one of our Radiant Barrier reflective insulation products for any residential or commercial application. Customer service is one of our strengths. When you call, you will speak to a knowledgeable radiant barrier expert.
How does Radiant Barrier work?
Radiant Barrier reflects heat. Traditional insulations, like blown-in, spray-on or rolled batts, only delay the transfer of heat. Heat naturally gravitates toward cold, so the challenge is keeping heat out of your home or building in the summer and retaining it during winter.
How does heat move to cold?
• Conduction: direct heat flow through a solid object like a wall or ceiling. If heat did not pass through solid objects, there would be no need for insulation.
• Convection: heat movement through the air. When heated, air expands and rises.
• Radiant: movement of heat from warm objects to cooler ones. The heat from the sun or a quartz space heater are examples of radiant heat.
Regular insulation doesn't stop heat gain or loss. It merely slows it down.
I already have plenty of insulation in my attic? Do I really need a Radiant Barrier?
Regardless of how much insulation you have in your attic, adding Radiant Barrier will save on heating and cooling expense and, more importantly, allow you to maintain a comfortable indoor temperature. In addition to up to 50% in energy savings, depending up a number of factors, Radiant Barrier never needs to be replaced and will extend the life of your heating and cooling equipment.
How does Radiant Barrier save me money in summer?
Radiant Barrier prevents 95 percent of the sun's heat rays from entering your structure. If installed on the rafters, Radiant Barrier will lower the attic temperature 22-28 degrees and save up to 50 percent on cooling cost, according to the Department of Energy.
How does Radiant Barrier save me money during the winter?
Just like wrapping a baked potato in aluminum foil keeps its warm longer by holding in the heat, covering your attic insulation with Radiant Barrier will retain the heat in your house. Measuring heat loss is much more difficult because of windows, doors, basements, etc. But Radiant Barrier installed in a basement, for example, will immediately result in warmer floors.
Where is Radiant Barrier installed?
Radiant Barrier can be stapled under the rafters or laid over existing insulation.
What is the "R" Value?
"R" value is a unit of resistance indicating how long it takes heat to pass through solid objects, including insulation. Radiant Barrier reflects heat instead of delaying it. Radiant Barrier products do have an "R" Value, but that is not what makes them effective.
Will Radiant Barrier damage my root?
No. Shingle manufacturers have certified that the use of Radiant Barrier in the attic will not damage the roof or void a warranty.
Do I have to remove my old insulation to install Radiant Barrier?
No. Radiant Barrier actually makes your present insulation more effective.
Has Radiant Barrier been tested by a qualified independent lab or government agency?
The US Department of Energy commissioned the Oak Ridge National Laboratory to conduct several tests to determine the Radiant Barrier's energy efficiency. ORNL constructed an attic assembly built to code with rafter spacing and ventilation. Theif large-scale climate simulator monitored attic temperatures in summer and winter-like conditions against a control assembly that had no Radiant Barrier installed.
• An attic without radiant barrier had the highest heating and cooling costs.
• IRCC - 20% improved cooling but no heating cost saving.
• Radiant Barrier OSB - 33% improved cooling and a 10% improved heating savings.
• A rafter-applied radiant barrier had a 50% improved cooling savings and 10% improved heating savings.
