Super R Diamond®

Radiant Barrier

Super R Diamond Product Main2

Highlights

Super R Diamond® radiant barrier was the first product developed by Innovative Insulation. Super R Diamond® barrier insulation is a two-sided reflective aluminized polyester film with reinforced scrim inside. It is designed to reflect radiant heat no matter what the season. This product is a reliable choice for retrofitting an existing structure. It can be stapled to the underside of the roof rafters in an attic or laid directly over mass insulation for a noticeable increase in energy savings and increased comfort level.

For residential retrofit, particularly in the attic laying over existing insulation, and some OEM applications.

Available in 500 and 1,000 sq ft rolls or custom lengths.

Only available in perforated 4' widths.

Frequently Asked Questions

Radiant Barrier is unlike mass insulation which only slows down or resists heat transfer. Radiant Barrier reflects heat. Heat always goes cold by natural law—the problem is how to keep the heat in the winter and how to keep it out in the summer. There are three ways in which heat goes from warm spaces to cold spaces: conduction is direct heat flow through a solid object such as a wall or a ceiling. Convection is heat movement through air, occurring when air is warmed. The heat expands, becoming less dense and rising. Radiation is the movement of heat rays across air spaces from one warm object to a cooler object. The heat we feel from a wood stove or a quartz space heater is 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 the winter, and to the living space in the summer. Regular insulation won’t stop radiant heat loss. Radiant heat must be reflected with a radiant barrier.

A1 SUMMER: “A radiant barrier system can stop 97 percent of the thermal radiation across an attic space. If it is not stopped, that radiant energy would be absorbed by the ceiling insulation and eventually be transferred to the living space below.” The Solar Collector, Quarterly Newsletter of the Florida Solar Energy Center.

“The heat storage capacity of reflective insulation is low. As a result, it does not store heat during summer days, only to pass it on down into the rooms of the house from the attic at night when coolness is most apt to be desired from the point of view of sleeping comfort.” Progressive Architecture, Nov. 1949, Page 76.

A2 WINTER: “CONCLUSIONS: Reflective foil retrofitted to fiberglass insulated…buildings is demonstrably effective in reducing heat loss… Installation of foil in uninsulated buildings would show even more pronounced reduction in heat loss.” Effects Of Reflective Foil On Heat Loss in Attic Floors and Metal Building Installations, Northeastern Illinois University, Prof. Charles Shabica, May 20, 1986.

No. Radiant Barrier actually makes your present insulation more effective.

No. Radiant Barrier has been used extensively in the south, showing no difference in roof temperatures, as confirmed by field tests.

Just 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 stay cooler. It helps to understand how Radiant Barrier will work for you if you think of other things that work in much the same way. Astronauts’ space suits keep body heat and reflect the sun’s heat away. Thermos bottles keep hot things hot and cold things cold. They are almost perfect insulators. The tight seal and air space prohibit heat transfer by conduction and convection. The reflective surfaces inhibit radiation 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.
