Radiant Barrier Attic Insulation

Hot Roofs = Hot Attics = Hot Homes

Florida’s year-round summer heat can turn your attic into an oven, often reaching temperatures over 140°. This damaging heat radiates through your insulation and into your living space, making your AC run harder longer and creating temperature imbalances throughout your living quarters. Our Super R Plus Heavy Duty® blocks 95% of radiant heat transference, which prevents the heat entering the attic and so creates a protective shield around your home.

How Does Radiant Barrier Work?

Unlike mass insulation which only slows down or resists heat transfer, Radiant Barrier reflects heat. Heat naturally turns cold because a warmer environment will always transfer heat to a cooler environment, so the goal is to keep heat in during winter and keep heat out during summer. There are three ways in which heat transfers from warm spaces to cold spaces:
Conduction: direct heat flow through a solid object like a wall or ceiling.
Convection: heat movement through air occurring when air is warmed. Warm air expands, becomes less dense and rises.
Radiation: movement of heat rays across air spaces from one warm object to another cooler one. The heat we feel from a wood stove or quartz space heater is an example of radiant heat.
All objects and bodies give off radiant heat! Even the insulation in your attic gives off radiant heat to the cold attic space in winter and to the living space in the summer. Regular insulation won’t stop radiant heat loss. It must be reflected with a radiant barrier.

Will Radiant Barrier Shorten the Life of My Shingles?

One common misconception regarding radiant barrier is that the heat reflecting off the radiant barrier back to the roof has the potential to increase the roof temperature and possibly damage the shingles. Performance testing by Florida Solar Energy Center demonstrated that the increase in temperature at the hottest part of the day was no more than a few degrees F. In fact, this study showed that radiant barrier had the potential to decrease the roof temperature once the sun went down because it prevented heat loss through the roof. RIMA International wrote a technical paper on the subject which included statements collected from large roofing manufacturers, and none said that radiant barrier would in any way affect the warranty of the shingles.

What Is The R-Value of Radiant Barrier?

R-Value is a measure of heat absorption (slowing the heat). Radiant Barrier is measured in reflectivity (blocking the heat).

Will Radiant Barrier Affect my Cell Phone Signal?

Typically, a modern-day cell phone won’t be affected by radiant barrier. First, our products are not made with copper or tin which block cell signals. Second, Radiant Barrier only covers the roof portion of the house. The signal goes from your phone to the cell tower in a straight line, generally never even going through the Radiant Barrier in the attic.

How Can Radiant Barrier Keep Me Warmer In The Winter?

Just like wrapping a baked potato in aluminum foil keeps it warm longer by holding in the heat, covering your attic insulation with Radiant Barrier holds the heat in the house. Another analogy would be that in winter Radiant Barrier works just like a space blanket which, although very thin and lightweight, holds in your body heat. A thin space blanket can keep you warmer than several heavy blankets.

How Does Radiant Barrier Keep Heat Out In Summer?

Like a space suit, Radiant Barrier reflects the sun’s heat before it can warm up the insulation in your attic. When the insulation stays cooler, your house will too. Just like a space suit or Thermos bottle, the reflective surface inhibits radiant heat transfer. If the bottle starts out hot, it stays hot because very little heat is transferred to the cooler outside. If it starts out cold, it stays cold because very little heat is transferred from the warmer outside.

What is the History of Radiant Barrier?

For the Apollo program, NASA helped develop a thin aluminum metalized film that reflected 95% of the radiant heat. A metalized film was used to protect spacecraft, equipment, and astronauts from thermal radiation or to retain heat in the extreme temperature fluctuations of space. The aluminum was vacuum-coated to a thin film and applied to the base of the Apollo landing vehicles. It was also used in numerous other NASA projects like the James Webb Space Telescope and Skylab. In the vacuum of space where temperatures can range from 250°F above to 400°F below zero and heat transfer is only by radiation. Radiant barrier is a Space Foundation Certified Space Technology(TM). Radiant barrier was inducted into the Space Technology Hall of Fame in 1996.
