What Is Radiant Barrier?

A radiant barrier is a highly reflective material that blocks thermal radiation and reduces heat transfer. Because it blocks radiant heat energy rather than absorbing it, a radiant barrier is unaffected by humidity. Green Energy Radiant Barrier™ also has an especially low emissivity, meaning it emits very little radiant heat from its surface. All of this results in cooler summers and warmer winters in your home.

How Does Radiant Barrier Work?

A radiant barrier keeps your home cooler by reflecting radiant heat from the sun away from your home. Without a radiant barrier, this heat would be radiated from your roof into your attic and the rest of your home.

Regular attic insulation doesn’t prevent heat conduction. It just slows it down. With a radiant barrier installed over your insulation, up to 97% less of this heat is conducted in your attic.

A Brief History of Radiant Barriers

Radiant barriers have a more interesting origin than you might think. The radiant barriers we know today actually developed out of original designs by NASA for the Apollo and Gemini missions.

Radiant Barrier FAQ’s

When implemented in a hot, sunny climate like San Antonio alongside other energy-saving products like energy-efficient windows and attic insulation, a radiant barrier can help you save as much as 35% on your annual energy bills. It can even allow you to downsize to a smaller HVAC system. These substantial savings will more than pay for the cost of the radiant barrier.
Heating and cooling often account for over half of your San Antonio energy bills. Saving on those expenses adds up. Because radiant barriers are so effective at stabilizing your home’s temperature, you’re able to drastically reduce energy costs. While actual savings will vary, San Antonio homeowners can save an estimated $1,200 dollars per year on their bills. That’s an extra $100 in your pocket every month!
Yes. Pure copper starts off at 98% reflective whereas pure aluminum starts off at 97%. Aluminum, copper, silver, and gold are the most heat reflective metals. Copper is more heat reflective than both aluminum and gold, so if you’re going to make a new radiant barrier more reflective, copper is the obvious choice. On top of that, Aluminum corrodes and oxidizes when exposed to water, or just high humidity, losing its reflective surface. This makes copper radiant barriers far more durable than aluminum radiant barriers.
Radiant barriers are most commonly installed between the roof and attic because the sun is likely to beat down on the surface of your roof and heat up your house. For people living in hot climates like San Antonio, radiant barrier can lower the temperature in your attic by as much as 70 degrees Fahrenheit.
Blown-in insulation alone does not prevent radiant heat loss entirely, and it only slows down warm air escaping from your main living spaces into your attic. When you install a radiant barrier over your insulation, it stops heat from escaping. This makes your home cozy and warm for less during the winter.
Radiant barrier on its own doesn’t have an R-value. R-value is used to classify traditional types of insulation and is a measure of how well the insulating material resists the conductive flow of heat. Green Energy Radiant Barrier™ works by blocking/reflecting heat rather than by absorbing it, as traditional insulation does.
