Radiant Barriers or Reflective Barriers
―Radiant barriers or reflective barriers inhibit heat transfer by thermal radiation. Thermal energy may also be transferred via conduction or convection, however, and radiant barriers do not necessarily protect against heat transfer via conduction or convection..‖
About Radiant barriers or Reflective Barriers
Reflectivity and Emissivity All materials give off, or emit, energy by thermal radiation as a result of their temperature. The amount of energy radiated depends on the surface temperature and a property called the emissivity (also called the "emittance"). Emissivity is expressed as a number between zero (0) and one (1) at a given wavelength. The higher the emissivity, the greater the emitted radiation at that wavelength. A related material property is the reflectivity (also called the "reflectance"). This is a measure of how much energy is reflected by a material at a given wavelength. The reflectivity is also expressed as a number between 0 and 1 (or a percentage between 0 and 100%). At a given wavelength and angle of incidence the emissivity and reflectivity values sum to 1 by Kirchhoff's law. Radiant barrier materials must have low emissivity at the wavelengths at which they are expected to function. For typical building materials, the wavelengths are in the mid- and long- infrared spectrum, in the range of 3 - 15 micrometres. Radiant barriers may or may not exhibit high visual reflectivity. This is because while reflectivity and emissivity must sum to 1 at a given wavelength, reflectivity at one set of wavelengths (visible) and emissivity at a different set of wavelengths (thermal) do not necessarily sum to 1. Though, it is possible to create visibly dark colored surfaces with low thermal emissivity. To perform properly, radiant barriers need to face open space (e.g., air or vacuum) through which there would otherwise be radiation.
History In 1860, a French scientist named Jean Claude Eugene Peclet experimented on the insulating effect of high and low emissive metals facing air spaces. Peclet experimented on a wide variety of metals ranging from tin to cast iron, and came to the conclusion that neither the color nor the visual reflectance were significant determining factors in the materials’ performance. Peclet calculated the reduction in BTUs for high and low emissive surfaces facing into various air spaces, discovering the benefits a radiant barrier in reducing the transfer of heat. In 1925, German businessmen Schmidt and Dykerhoff filed for patents on reflective surfaces being used as building insulation because recent improvements in technology allowed low emissivity aluminum foil to be commercially viable. This became the launching pad for radiant barrier and reflective insulation around the world, and within the next 15 years, millions of square feet of radiant barrier were installed in the US alone. Within 30 years, radiant barrier was making a name for itself, and was included in projects at MIT, Princeton, and Frank Sinatra’s residence in Palm Springs, CA.

Applications
Space Exploration For the Apollo program, NASA helped develop a thin aluminum metalized film, which 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, in addition to 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, heat transfer is only by radiation, so a radiant barrier is much more effective than it is on earth, where 5% to 45% of the heat transfer can still occur via convection and conduction, even when an effective radiant barrier is deployed. Radiant barrier is a Space Foundation Certified Space Technology(TM). Radiant barrier was inducted into the Space Technology Hall of Fame in 1996.
Textiles As far back as the 1970s, sheets of metalized polyester called space blankets have been commercially available as a means to prevent hypothermia and other cold weather injuries. Because of their durability and light weight, these blankets are popular for survival and first aid applications. Swarms of people can be seen draped in reflective metalized film after a marathon, especially where the temperatures are particularly cold, like during the annual ING New York City marathon which takes place in the fall.
Window Treatments Windows glass can be coated to achieve low emissivity or ―low-e‖. Some windows use laminate polyester film wherein at least one layer has been metalized using a process called sputtering. Sputtering occurs when a metal, most often aluminum, is vaporized and the polyester film is passed through it. This process can be adjusted to control the amount of metal that ultimately coats the surface of the film. These metalized films are applied to one or more surfaces of the glass to resist the transfer of radiant heat, yet the films are so thin that they allow visible light to pass through. Since the thin coatings are fragile, and can be damaged when exposed to air and moisture, manufacturers typically use multiple pane windows. While films are typically applied to the glass during manufacturing, some films may be available for homeowners to apply themselves. Homeowner applied window films are typically expected to last 10–15 years.
Construction Industries
Roofs and Attics Radiant solar energy strikes the roof, heating the shingles, felt paper and roof sheathing by conduction, and causing the underside of the sheathing and the roof framing to radiate heat downward through the attic toward the attic floor. When a radiant barrier is placed between the roofing material and the insulation on the attic floor, much of the heat radiated from the hot roof is reflected back toward the roof and the low emissivity of the underside of the radiant barrier means very little radiant heat is emitted downwards. This makes the top surface of the insulation cooler than it would have been without a radiant barrier and thus reduces the amount of heat that moves through the insulation into the rooms below the ceiling. This is different from the cool roof strategy which reflects solar energy before it heats the roof, but both are means of reducing radiant heat. According to a study by Florida Solar Energy Center, a white tile or white metal cool roof can outperform traditional black shingle roof with a radiant barrier in the attic, but the black shingle roof with radiant barrier outperformed the red tile cool roof. Some roofing companies even offer the option of installing both a radiant barrier and a cool roof, for optimum performance. There are a wide variety of factors to consider in deciding whether or not to use a cool roof and/or a radiant barrier. For installing a radiant barrier under a metal or tile roof, the radiant barrier may be applied directly over the roof sheathing. Then furring strips (1x4s) are applied over the radiant barrier before the metal or tile roof is applied. The furring strips ensure that the radiant barrier faces into a sufficient air space. If an air space is not present or is too small, heat may be able to conduct through the radiant barrier. Since the metal in the radiant barrier is highly conductive, the heat transfer would all be through conduction and the heat would not be blocked. According to the US Department of Energy, ―Reflective insulation and radiant barrier products must have an air space adjacent to the reflective material to be effective.‖ The most common application for a radiant barrier is facing into attics. For a traditional shingle roof, radiant barrier may be applied over the rafters or trusses and under the roof decking. This application method has the radiant barrier sheets draped over the trusses of rafters, creating a small air space above with the radiant barrier facing into the entire interior attic space below.

Another method of applying radiant barrier to the roof in new construction would be to use radiant barrier that is pre-laminated to OSB or roof sheathing. Manufacturers of this installation method often tout the savings in labor costs in using a product that serves as roof decking and radiant barrier in one. To apply radiant barrier in an existing attic, a radiant barrier may be stapled to the underside of the roof rafters. This method offers all the same benefits as the draped method, in that dual air spaces are provided. However, it is essential that the vents still be allowed to remain open to prevent moisture from being trapped in the attic. In general, it is preferred to have the radiant barrier applied to the underside of the roof with an air space facing down to prevent the accumulation of dust, preventing the radiant barrier from conducting. The final method of installing a radiant barrier in an attic is to lay it over the top of the insulation on the attic floor. While this method can be more effective in the winter there are a few potential concerns with this application, which the US Department of Energy and the Reflective Insulation Manufacturers Association International feel the need to address. First, a breathable radiant barrier should always be used here. This is usually achieved by small perforations in the radiant barrier foil. The vapor transmission rate of the radiant barrier should be at least 5 perms, as measured with ASTM E96, and the moisture in the insulation should be checked before installation. Second, the product should meet the required flame spread, which includes ASTM E84 with the ASTM E2599 method. Lastly, this method allows for dust to accumulate over the top surface of the radiant barrier, potentially reducing the efficiency over time.
Energy Savings According to a study by the Building Envelope Research Program of the Oak Ridge National Laboratory, homes with air-conditioning duct work in the attic in the hottest climate zones, e.g., the deep south of the U.S., could benefit the most from radiant barrier interventions, with annual utility bill savings up to $150; whereas homes in milder climates, e.g., Baltimore, could see savings about half those of their southern neighbors. On the other hand, if there are no ducts or air handlers in the attic, the annual savings could be even much less, from about $20 in Miami to $5 in Baltimore. Nevertheless, a radiant barrier may still help to improve comfort and to reduce the peak air-conditioning load.
Shingle Temperature One common misconception regarding radiant barrier is that the heat reflecting off the radiant barrier back out the roof has the potential to increase the roof temperature and possibly damage the shingles. This is simply not the case. Performance testing by Florida Solar Energy Center conclusively proved that the increase in temperature at the hottest part of the day was no more than about 5 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 was preventing the heat loss through the roof. RIMA International wrote a technical paper on the subject, where they collected statements from the largest roofing manufacturers, and none said that radiant barrier would in any way affect the warranty of the shingles.
Attic Dust Accumulation When laying a radiant barrier over the insulation on the attic floor, it is possible for dust to accumulate on the top side. Many factors like the dust particle size, dust composition and the amount of ventilation in the attic will affect how dust accumulates and the ultimate performance of radiant barrier in the attic. A study by Tennessee Valley Authority mechanically applied a small amount of dust over a radiant barrier and found no significant effect when testing for performance. However, TVA referenced a previous study which stated it was possible for the radiant barrier to collect so much dust that its reflectivity could be decreased by nearly half. It is not true that a double-sided radiant barrier on the attic floor is immune to the dust concern. The TVA study also tested a double-sided radiant barrier with black plastic draped on top to simulate a heavy dust accumulation, as well as a single-sided radiant barrier with heavy kraft paper on the top. The test indicated that the radiant barrier was not performing, and the small air spaces created between the peaks of the insulation were not sufficient to block radiant heat. Dust should be a factor of consideration in determining the radiant barrier attic application that is right for you.
Walls Radiant barrier may be used as a vented skin around the exterior of a wall. Furring strips are applied to the sheathing to create a vented air space between the radiant barrier and the siding, and vents are used at the top and bottom to allow convective heat to rise naturally to the attic. If brick is being used on the exterior, then a vented air space may already be present, and furring strips are not necessary. Wrapping a house with radiant barrier can result in a 10% to 20% reduction in the tonnage air conditioning system requirement, and save both energy and construction costs.
Floors

Radiant barriers are also quite effective in floor systems above unheated basements and crawl spaces. The radiant barrier may be either stapled below the floor joists, creating a single reflective air space, or between the joists, followed by some type of sheathing. Radiant barrier works extremely well in this application for two reasons. First, a radiant barrier that is not perforated for breathability acts as an excellent vapor barrier. This means that ground moisture will not be able to pass through the radiant barrier and enter the living space. Secondly, the floor is the only part of the building where the heat flow is always down, unlike a roof where the heat would be coming down during the summer and rising to escape in the winter.[15] When the heat flow is down, 93% of the heat is radiant heat, which is exactly what the radiant barrier is designed to block.
Types of Radiant Barriers Radiant barriers come in a variety of forms, including reflective foil, reflective metal roof shingles, reflective laminated roof sheathing, and even reflective chips, which can be applied over loose-fill insulation. The reflective material, usually aluminum, is applied to one or both sides of a number of substrate materials. Substrate materials include kraft paper, plastic films, cardboard, oriented strand board, and air infiltration barrier material. Some products are fiber-reinforced to increase the durability and ease of handling.
Also, radiant barriers—which don't provide a significant amount of thermal insulation—can be combined with many types of insulation materials. These combinations are called reflective insulation systems. In these combinations, radiant barriers can also act as the insulation's facing material.
Installation A radiant barrier's effectiveness depends on proper installation. Therefore, it's best to have a certified installer do it.
If you want to install a radiant barrier yourself, obtain instructions and safety precautions from the manufacturer. Carefully study and follow these directions. You should also check your local building and fire codes.
Radiant barriers can be installed between the roof sheathing and attic floor insulation, in cavity walls, and around door openings, water heaters, and pipes. It's easier to incorporate radiant barriers into a new home, but you can install them in an existing home too.
An installer typically drapes a rolled-foil radiant barrier foil-face down between the roof rafters to minimize dust accumulation on the reflective faces (double-faced radiant barriers are available). This is generally done just before the roof sheathing goes on if it's not too windy, but it can also be done afterwards from inside the attic by stapling it to the bottom of the rafters.
When installing a foil-type barrier, it's important to allow the material to "droop" between the attachment points to make at least a 1.0 inch (2.5 cm) air space between it and the bottom of the roof. This air space has mainly two functions: it creates an air channel for the soffit and ridge ventilation system to work more effectively, and it acts as a second reflector since there are two shiny sides (one facing up/ one facing down.)
Some builders also try to attach the radiant barrier directly onto the roof sheathing prior to their installation on the roof rafters. However, a more effective method is to simply buy foil-faced plywood or oriented strand board sheathing instead. There are also metal roof shingles that have a reflective underside. If you need roof shingles, these are a practical option, but the cost of this type of radiant barrier is considerably higher than other types.
A radiant barrier installed on top of attic floor insulation is more susceptible to dust accumulation. This less desirable installation method may also trap moisture in fibber insulation and is not cost effective in cold climates. A radiant barrier installed on the cold side of the insulation acts as a vapour barrier in the wrong location. When warm moisture carrying house air leaks into the attic in the winter, it may condense on the underside of the barrier. Even a perforated radiant barrier can trap moisture in cold climates since the water can freeze in the small holes and seal them. Because of these hazards, it's strongly recommended that you NOT apply radiant barriers directly on top of the attic floor insulation.
Our radiant barriers and reflective insulation products are available for purchases by homeowners, retail store operators, resellers, installers, distributors and all other consumer types.
