Customer Questions & Answers

It says R3.7 to R21, depending on application.

What would its R value be if I used a single layer of it to block out sunlight on the inside of a picture window?
Asked by: David
There are three ways that heat is exchanged: Radiation, Conduction and Convection. R values represent a product's ability to slow the flow of heat by conduction. It really isn't a measure of its ability to handle radiant energy. A radiant barrier is basically intended to continuously reflect back heat rather than slow the rate of conduction. The Department of Energy has a nice description of a radiant barrier: http://energy.gov/energysaver/radiant-barriers

can this product keep pipes from freezing?

would this work if I put this around my trailer to keep pipes from freezing during winter
Asked by: Michael
Dear Michael: The reply from the Reflectix Technical Group rep was interesting. Two key points: (1) He/she stated: "Our products are tested in the same manner as fiberglass and foam." This is not correct. Fiberglass and foam insulation manufacturers provide an R value "per inch" for their products. You can see this on the Home Depot website, e.g. with Foamular foam board (R-5 per inch) and Owens Corning fiberglass insulation (from R-11 at 3.5" to R-49 at 14") Reflectix does not provide a similar R value for their products, because the shiny bubble wrap has an R value of just 1. Reflectix tests and R value claims are all based on "assemblies", e.g. a simulated wall with drywall, wood studs, an air gap and a layer of Reflectix. (2) Reflectix claims only R-2 when it is used for pipe wrap -- and no ASTM test results are shown for cold winter applications. The performance of reflective / radiant barrier products varies significantly with the temperature, and it would be helpful if Reflectix would provide ASTM test results for each application assembly -- in winter and summer. Fortunately, Home Depot offers other pipe insulation products that are more effective, e.g. foam and fiberglass pipe sleeves with R-3, which can be combined for R-6.

Can this be used to go behind paneling on basement outer walls for insulation?

Asked by: cabcab09
Dear CabCab and Home Depot customers: I am puzzled by the recent reply from someone in the Reflectix Technical Group. They said, "Respectfully, the responder from Mass. is in error. Most Reflectix assembly R-values are valid year around (we state specific thermal performance “per application”). Our products are tested in the same manner as fiberglass and foam. " It would be helpful if the Reflectix Technical Group could provide more details on the "errors". First, Reflectix is NOT tested in the same manner as standard insulation, e.g. fiberglass, rock wool, foam board and cellulose. You can see this on the Home Depot website. Standard insulation is tested as a material with an R value per inch of thickness -- for example, R-13 for 3.5" of Owens Corning fiberglass, and R-5 per inch with Foamular foam board. In contrast, Reflectix is always tested as part of an assembly, e.g. a simulated wall with 2x4 studs, dry wall, an air space and layer of Reflectix. Why? Because the shiny bubble wrap that Reflectix is made from has very little R value by itself -- only R-1. The sealed air gap that you must build / create provides almost all of the claimed R values, not Reflectix. Second, the performance of Reflectix and other radiant barriers varies with the temperature -- better in summer and poor in winter. In a cathedral ceiling, for example, Reflectix claims R7 in summer but only R1 in winter in the northern USA. Why? In summer, a hot roof emits lots of radiant (infrared) energy that can be reflected. In winter, cold cannot be 'reflected' and warmer air inside your home does not emit much infrared energy. Reflectix should provide ASTM test reports that show R-value performance in summer AND winter temperatures for walls, crawlspaces, ducts and other applications and post these reports on their website. I look forward to more detailed information from the Reflectix Technical Group. Mark

Can this be applied to the inside of a metal garage door to help keep the garage cooler?

Asked by: tallred67
Dear TallRed: As GoldenHVAC already noted, Reflectix bubble wrap by itself provides almost no insulation -- R-1 or less. All of the R value claims are based on an air gap that you must create / build. This air gap must also be sealed -- or the hot air will simply flow into your garage like it did before. It would be very difficult to create a 3/4"+ thick air gap (the minimum that Reflectix recommends) and keep it sealed on a moving garage door. Fortunately, Home Depot sells another garage door insulation product that is reliable and more effective with R-8 performance. See: Owens Corning Model # GD01, Home Depot Internet #202257272 Store SKU #744925 I hope this is helpful. Mark

48 in. x 100 ft. Double Reflective Insulation is rated 4.6 out of 5 by 49.
Rated 5 out of 5 by from good energy saver I installed 2 rolls of the reflectix 4' x100' radiant barrier in my attic as well as a 10W solar gable fan. The measured temperature of the attic has dropped 10-15 degrees even though I have only done about 40% of the attic space with the barrier. I recommend using a lightweight staple gun like a JT21 to attach the product to the trusses since it may involve a lot of stretching and working in tight spaces.

Rated 5 out of 5 by from Very easy to install, no mess, looks great too Compared to all other types of insulation this is easy and clean to install. I used on HVAC supply ducts. No fibers or dusting from the product at all. Cuts easily with a scissor or utility kife and straight edge. Very strong and lightweight at the same time. I simply made spacers out of leftover strips of the material to get the best R factor as the air space doubles the R. Metallic tape sticks very well. While there are other products with higher R factors, none are as easy and clean to install. Highly reocmmended.

Rated 5 out of 5 by from Insulated the heat pump with it My sister's house in Phoenix AZ did not have insulation on the return air ducts running through the attic. I bought a 4'X 125' roll of Reflectix insulation, insulated all the return air ducts, coated the exterior of her heat pump air handler (factory insulated with 1" fiberglass to about R3?), had enough left over to coat the walls and ceiling of the mechanical space in the attic that the heat pump is located in. Had 16' left over, and insulated her garage roll up door as well. I also use this in my motorhome to cover the windshield, roof vents, and some windows. It keeps out the cold, light and heat in summer.

Rated 5 out of 5 by from Big difference I put this up on the rafters in my garage and the temp went from 105 to about 80 in there in the dog days of summer. Going to put this in my attic of my house next..

Rated 5 out of 5 by from Reflectix Rocks An absolutely outstanding product. We used Reflectix to insulate the duct work in our basement. Due to the very small tolerances we required a thin, flexible insulator and this was the only fit. Using the easy to follow instructions we have already seen a noticeable drop in our utility bill whilst seeing an increase in whole house comfort. The larger 4ft roll cuts easily, if required, and makes installation a breeze. We did a cost comparison against fiberglass and Reflectix worked out to be considerably more affordable whilst offering comparable or better insulating properties.

Rated 5 out of 5 by from Makes a big difference I am in the process of installing Reflectix radiant barrier in my attic. The job is about 50% complete. It started sleeting today, and as I went out and looked at my roof, I can tell exactly where the radiant barrier is and isn't! All of the sleet has melted off where there is no radiant barrier. Sleet still remains on the roof top in the areas with the radiant barrier.

Rated 5 out of 5 by from Easy to work with and effective Received two 100' rolls right on time and began to insulate the pony walls and south wall in my attic. The product went up very easy and after my first wall I found it much easier to measure and cut first before installing. Cuts very easily with a straight edge and a sharp utility knife. I can already feel the difference in the attic temp. I saved over $1,000 doing this myself and it only took me four hours.

Rated 5 out of 5 by from Easy to work with, good value I bought this to insulate the inside of my steel garage door, and was debating over the 2 foot and 4 foot widths. For whatever reason 2 of my garage door panels are different heights than the other two, so I would have to custom cut anything I bought. This stuff is very easy to work with, rolls out nicely, cuts easily, and I was able to install it using aluminum foil tape without any problems. My only concern is that it may not be enough insulation (R-factor) for my garage, but that is not the problem of the product, it performs as advertised.
