Radiant Barrier Insulation
R+HEATSHIELD Radiant Barrier Foil
R+HEATSHIELD is Innovative Energy's line of radiant barrier insulation products made from a woven polyethylene material covered by a foil film. This metalized film provides a reflective surface that blocks 95 percent of radiant heat, so it helps keep spaces cooler in summer and warmer in winter. R+HEATSHIELD can dramatically improve thermal performance and energy efficiency, keeping energy costs lower and interior spaces more comfortable.
The main difference between a radiant heat barrier and a reflective insulation product relates to the way in which it is installed. Reflective insulations are typically installed within cavities that incorporate air spaces between the foil insulation and the cavity materials, as in a wall. Radiant barrier insulation is typically installed with one reflective surface facing a large open air space, which makes it ideal for insulating an attic.

Q: What is a radiant barrier and why should I use one?
A: A radiant barrier is reflective material that is used to effectively block the transfer of radiant heat. Radiant barriers typically come in sheets with a highly reflective surface on one or both sides, depending upon the application. A good radiant barrier blocks 95 percent of radiant heat transfer, making it highly effective at controlling the transfer of heat from one space to another. For example, installed properly in an attic, a radiant barrier will make the attic cooler in the summer, leading to lower cooling costs and a more comfortable home.
Q: What types of applications are appropriate for R+HEATSHIELD?
A: There are many applications for the building industry (e.g., residential, industrial, commercial and agricultural). R+HEATSHIELD is thin and lightweight, so it's ideal for controlling temperatures in any space-constricted situation (such as in a recreational vehicle or inside machinery that requires temperature control in order to function properly).
Q: Why do I need an air space next to the R+HEATSHIELD surface?
A: All Low E materials achieve the majority of their thermal performance ONLY when they face an air space. “E” stands for emissivity, the converse of reflectivity. Low E surfaces like R+HEATSHIELD, when facing an air space, will either reflect 95 percent of the heat that is directed to them across the air space, or they won’t emit more than 5 percent of the heat that is conducted to them.
Q: Can I install R+HEATSHIELD by myself?
A: R+HEATSHIELD is a perfect do-it-yourself product to enhance the current insulation in your attic. It is lightweight, easy to install and will reduce energy consumption. Scroll down this FAQs section to see our "FAQs for Residential Attic Installation". Also, scroll down this page to see the R+HEATSHIELD Installation Guide.
Q: Do I need special tools to install R+HEATSHIELD?
A: No. R+HEATSHIELD can be cut easily with a razor blade or scissors and installed with common staples, nails or screws.
Q: Do I need to tape the seams?
A: To achieve an absolute moisture barrier, taping the seams is recommended. Seams can be easily taped using our reflective tapes. However, if an absolute moisture barrier is not a concern, such as in a horizontal application in attic spaces, taping seams is not necessary.
Q: All of the equipment in my metal building is getting damaged from condensation drips. Do you have a product that can help?
A: R+HEATSHIELD can help reduce condensation problems because it creates a buffer between interior and exterior temperatures.
Frequently Asked Questions for
How Does It Work?
R+HEATSHIELD is a radiant barrier. Unlike mass insulation, which slows down heat transfer, R+HEATSHIELD reflects heat. To stop radiant heat, you must reflect it with a radiant barrier like R+HEATSHIELD.
How Will R+HEATSHIELD Keep Me Warmer In The Winter?
Just like wrapping a baked potato in aluminum foil keeps a potato warm longer by holding the heat in, covering your attic insulation with R+HEATSHIELD holds the heat in the house. Ever seen a marathon finisher wrapped in a "space blanket"? Marathon runners know that a thin space blanket can keep a person warmer than several heavy blankets. R+HEATSHIELD acts like a space blanket for your house in the winter; even though it's very thin and lightweight, it holds heat in.
Do I Have To Take My Old Insulation Out Before Installing R+HEATSHIELD?
No. R+HEATSHIELD actually makes your present insulation more effective.
If I Lay Perforated R+HEATSHIELD On My Regular Insulation, Will It Cause A Moisture Problem?
No. The tiny holes in perforated R+HEATSHIELD allow moisture to escape from your regular insulation.
Okay, If R+HEATSHIELD Keeps Heat In During The Winter, How Can It Keep Heat Out In The Summer?
R+HEATSHIELD's reflective surface stops up to 94 percent of radiant heat from the sun as it beats down on your house. It reflects the sun's heat away before it can warm up the insulation in your attic. With fiberglass, foam or cellulose insulation, heat transfer is merely slowed down; it’s just a matter of time before living spaces heat up. When radiant heat is reflected away, it never gets a chance to reach your living space, so your house stays cooler. A cooler house means lower energy costs; installing R+HEATSHIELD can pay for itself pretty quickly.
Where Do You Install R+HEATSHIELD?
For attic installation, the perforated (not solid) version of R+HEATSHIELD should be used. The preferred application for an attic is stapled to the underside of the roof rafters. In some attics this is not a good option, either because the roof pitch is too low to physically reach the rafters or there may be too much blown-in mass insulation on the floor precluding a good working area to do the installation. In these situations, please contact Innovative Energy for other installation options.
Will R+HEATSHIELD Make My Attic Hotter In The Summer?
No. In fact, research has confirmed that summertime attic temperatures will be much cooler with R+HEATSHIELD in place.
I Already Have Plenty Of Insulation In My Attic. Do I Really Need R+HEATSHIELD?
Regardless of how much insulation you have in your attic, adding perforated R+HEATSHIELD could save on your heating and cooling expense, and keep you much more comfortable.
Has R+HEATSHIELD Been Tested By A Qualfied Independent Laboratory Or Government Agency?
The Florida Solar Energy Center at Cape Canaveral has tested radiant barriers in both small-scale laboratories and in full-scale building models. Their results indicate that radiation barriers like R+HEATSHIELD can provide significant resistance to heat transfer.
Tests conducted by the Tennessee Valley Authority, Oak Ridge Laboratories in Tennessee and the University of Mississippi support the findings from the Florida Solar Energy Center.
Northeastern Illinois University conducted winter tests in residential and commercial structures using infrared thermograph photography. The photos showed significant resistance to heat transfer with a radiant barrier vs. with regular (mass) insulation alone.

Stapled Under Roof Rafters
Staple solid R+HEATSHIELD from the ridge board down to the eave or horizontally across the rafters, whichever is easier. If ridge venting is used, staple right to the ridge board. If other roof and/or gable venting is used, leave a 2" opening below the ridge board and above the floor joists as shown to prevent trapping heated air. Never block any venting with R+HEATSHIELD.
Over Crawlspaces or Unfinished Basements
Staple solid R+HEATSHIELD along the bottom of the floor joists. Tape all joints with appropriate tape for a vapor barrier. In Northern climates be aware that the winter temperature in the basement or crawlspace will drop considerably.
Over Purlins and Girts
Staple or tape to the ridge board of post-frame or steel buildings and pull down to the eave. The extra strength of R+HEATSHIELD easily withstands heavy use. Overlap R+HEATSHIELD 2" and fasten roof and side panels over it.
R+HEATSHIELD can span up to eight feet unsupported. Use heavy-duty staples every 8" - 10", or tapping screws every 12" to 16". The superior strength of R+HEATSHIELD will support 3" to 5" of fiberglass insulation laid on top, if desired. Space fasteners every 6" when supporting added insulation.
Over Joists Under Roof Sheathing
Lay R+HEATSHIELD over rafters allowing it to “drape” several inches. Staple as necessary to hold in place until roof sheathing is fastened down. The air space created by draping will reflect downward heat intrusion, while the bottom side will stop heat transfer with its low emittance surface. The same effect occurs, but in reverse, in the winter months to stop heat loss.
