Dear David and Home Depot customers: I am puzzled by the new reply from a Reflectix Technical Group rep in Indiana. He / she stated: "Respectfully, the responder from Mass. is in error (his second comment). Reflectix assembly R-values are valid year around. Our product assemblies are tested in the same manner as fiberglass and foam, in a ASTM C1363 Hot Box."

It would be helpful if the Reflectix Technical Group could point out exactly what was "wrong". For example:

(1) Fact: Reflectix was required by the US Federal Trade Commission (FTC) to publish a list of actual R values for various applications and assemblies, which is available on the Reflectix website. This is driven by the FTC's "R Value Rule." It is important to look closely at the claims for each application. In a standard 2x4 wall, for example, Reflectix says, "R 3.9 (total assembly with R-13 batt = R-14)" In other words, if you add Reflectix on top of standard R13 fiberglass insulation, you only gain 1 R -- not 3.9 R.
(2) Fact: The R values that Reflectix claims for cathedral ceilings vary widely between summer and winter, e.g. R7 in summer and R1 in winter in the northern US. Curiously, Reflectix does not provide R value results for other applications in summer and winter, e.g. for walls or crawlspaces.

(3) Fact: Cold in the winter cannot be 'reflected' like radiant (infrared) heat from a roof in the summer. Independent tests show that radiant barrier performance drops along with the temperature -- just like the Reflectix R value in a cathedral ceiling. It would be helpful if Reflectix would publish ASTM test reports for each application, in winter and summer, on their website.

(4) Fact: The shiny plastic bubble wrap that Reflectix is made of provides very little R value; test results show R1 or less. Almost all of the claimed R values depend on a air gap that you must create / build when you install it -- as shown in Reflectix installation guides. The only exception is in an attic, where a radiant barrier can simply be laid on top of existing insulation.

Another key point that is often overlooked: dust accumulation. Three independent tests have shown that dust accumulating on the shiny surface steadily degrades performance.

I look forward to a reply from Reflectix technical support with more details.

It would work best if the insulation where on the outside, so that the sunlight would reflect the heat away, and none of it would come inside. What heat did get through the insulation would still be outside the window.
With the insulation on the inside of the window, any heat (mostly infrared heat) that gets into the window, it will still stay inside the window, less some heat conducted outside due to the heated air between the insulation and glass window leaking outside (presuming it is cooler air outside than between the insulation and glass) through the R-1 un-insulated glass pane.
So while the insulation on the inside will offer cooler inside air temps, and less heat absorbed, if there where a way to put shutters on the outside, with reflex insulation between say two layers of 1/8" plywood, that is painted to make it attractive and water resistant, this would lower the heat absorbed by the window.
So I would make an educated guess that you might have R-4 insulating value, but only if you install the reflectix in such a way that you do not turn it into a air curtain. So you would need to seal the insulation to the wall above and below the window. If not sealed, then the air say it is 95F outside, and 75F inside, you might have 110F air between the window and reflectix. This super hot air will be thinner and lighter than the 75F inside air, and will drift upwards, bringing in 75F air below to replace it. This will greatly reduce the effectiveness of the insulation. while supplying the cool room with a few cubic feet per hour of 110F air. Read Less

Regarding the wide range of R values, the Federal Trade Commission forced Reflectix to publish a list of R values based on actual tests, which range from R1 to R21. Do a search for "FTC Fact Sheet" on the Reflectixinc web site. A scanned copy is attached below.

The R value varies so widely due to the depth of the sealed air gap(s) you must create or build, which actually provide almost all of the insulation. The shiny bubble wrap has almost no R value. You cannot simply apply Reflectix to a wall, for example, and achieve any R value. Reflectix also performs poorly in winter, because cold cannot be 'reflected' and the warmer air in your house is not radiant. Reflectix claims R7 in a cathedral ceiling in summer, for example, but only R1 in winter in the northern US.

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. See: Armacell Model HST07812, Home Depot Internet #100585113 Store SKU #420390 and Model F13XAD, Home Depot Internet #100118939 Store SKU #806938 Store SO SKU #1000091823

Home Depot sells other insulation products for pipes that can help to prevent freezing during winter. For example: Everbilt Model # ORP05812, Home Depot Internet # 204760811 Store SKU # 1000031790. You can add more protection by adding another layer with fiberglass insulation tubes that can fit over foam tubes, e.g.: Model # F15XAD, Home Depot Internet # 100162619 Store SKU # 170795. If you live in a climate with very cold winters or if you need to protect a group of pipes, you can add another layer by wrapping the pipes with fiberglass HVAC insulation: Model # INSWRP60, Home Depot Internet # 100152008 Store SKU # 363984.

Use foil HVAC tape to attach and these products and close the slits on the foam and fiberglass tubes, to prevent air leaks. See: Nashua Tape Model # 1207792, Home Depot Internet # 100030120 Store SKU # 915245 DO NOT use silver fabric "duck" tape.

Dear Michael: Go to the Reflectix website and read their product info carefully. First, "reflective insulation" can reflect radiant heat, e.g.t from a hot metal roof in summer. Cold cannot be reflected, so the R value is near zero. Reflectix claims R7 with a cathedral ceiling in summer, for example, but only R1 in winter. Second, reflective insulation only works if you build / create a sealed air pocket on one side. This would be very difficult with your trailer.
Here are a few recommendations:
(1) Foam board is a good solution to create an insulated skirt under your trailer, with high R ratings, easy installation and water resistance. Home Depot carries a number of products. Foamular XPS foam board is tough and water resistant.. See: Owens Corning, Home Depot model # 24DD Internet # 100320335 Store SKU # 528022 Avoid foam board made from polyisocyanurate, which will absorb water.
(2) Skirt vs floor: Insulating the skirt will work only if you can seal all of the air leaks. An air seal around the entire skirt will also be difficult to maintain. A good alternative would be to fasten foam board to the bottom (floor joists) of your mobile home. If it gets very cold where you live, you may need to do both.
(3) Multiple layers: Depending on where you live and how cold it gets, you may need to add multiple layers of foam board. (This will only work if you pick the 'floor' option.) R13 to R30 is recommended for floors, and foam board offers R4 to R5 per inch. Run each layer at a 90 degree angle to the previous layer, to improve the air seal. Do a Google search for "Recommended levels of insulation" on the EnergyStar website, to find the R recommendations for your area.
(4) Carefully seal air leaks: Whether you choose the 'skirt' or 'floor' approach (or both), be sure to carefully seal all of the edges and joints to block air leaks. The 'Windows and Doors' version of Great Stuff works well; it remains flexible after it cures, to prevent cracks as things expand, contract and shift. For flat surfaces and joints, a thick layer of DAP 230 is best. (If you choose the 'skirt' approach, the bottom edge will be the most difficult; you would need to dig a small trench around the perimeter and bury the edge of the foam board in the soil.)
(5) Insulate exposed pipes: Whether you choose the 'skirt' or 'floor' approach (or both), you should begin by insulating your exposed pipes. For small water lines, start with rubber foam insulation, e.g. Pratt Retail Specialties, Home Depot Model # PI16RSS Internet # 204759170. If you live in an area with cold winters, add a second layer of fiberglass pipe insulation that will fit over the first foam layer, e.g. Home Depot Model # F15XAD Internet # 100162619 Store SKU # 170795 Each layer provides ~R3 insulation. Be sure to seal all of the slits to block air leaks with HVAC foil tape; the built in glue will not last.. Special pieces are available for 90 degree angles, e.g. Frost King Model, Home Depot # ELB1H Internet # 202262370 Store SKU # 632932
(6) Foam board is flammable, so be sure to avoid any sources of heat, e.g. a furnace, exhaust duct, etc. Use Roxul rock wool around any heat sources. Look for: Roxul Model # RXCB351525 Internet # 202090820 Store SKU # 974419

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.

Answer: 
You can use Reflectix on a basement wall. The correct appliction would be to put 2" x 2" furring strips on the wall and then staple the Reflectix between the strips so there is a 3/4" air space between the product and the wall and between the product and the paneling. This will get you the air space needed between Reflectix and the wall and the paneling to yield an R-value of 6.

Dear CabCab09: Yes -- with a few caveats: (1) Reflectix has almost no insulation value itself, and requires an air gap that you must create or build to achieve the R values claimed on the package. Be sure to read the directions for wall applications on the Reflectix Inc. website. (2) Reflectix is much less effective in winter vs summer, because there is little radiant heat for the shiny surface to reflect. Look for the Federal Trade Commission Fact Sheet on the Reflectix website. With a cathedral ceiling, for example, the R value drops from R6 in summer to R2 in winter, in the southern US. The change is even more dramatic in the northern US: R7 in summer to R1 in winter.
Home Depot sells more effective insulation for basement walls, e.g. Foamular XPS foam board which provides a solid R5 per inch, winter and summer. XPS does not absorb water and serves as a vapor retarder / barrier depending on thickness, so it is ideal in a basement where water vapor is an issue. A few tips:
(1) If your inner 2x4 walls are not built yet, glue 2" thick Foamular XPS panels to your concrete walls, with Loctite Power Grab Heavy Duty Construction Adhesive, Model # 1589157 Internet # 203009262 Store SKU # 495275. Seal the joints and edges with DAP 230 sealant, to block air leaks and water vapor. Large gaps can be filled with Great Stuff foam; use the 'Windows and Doors' version in the blue can, which remains flexible. Then build your interior 2x4 wall, in front of the foam layer, so the studs do not touch the concrete wall. To boost the R value, add Roxul rock wool batts between the studs. Look for: Model # RXSS31525 Internet # 202531875 Store SKU # 982937
(2) If your inner 2x4 walls have already been built, cut pieces of 2" thick Foamular to fit between the studs, next to the concrete wall or outer sheathing. Seal all of the edges and joints with Great Stuff 'Windows and Doors' in the blue can, to block air leaks and water vapor. (We used this technique with a home on the shore in Massachusetts; a photo is attached.)
(3) If you have sufficient ceiling height in your basement, also cover the concrete floor with 1" XPS and carefully seal all of the joints and edges with a generous layer of DAP 230. If you have any problems with water in your basement, however, use DriCore panels which have a rubber layer on the bottom and a gap to allow moisture to dry. Look for Model # CDGNUS750024024 Internet # 202268752 Store SKU # 361018
(4) Also read up on fire blocking, which is required at the top of basement walls, stairs, etc. Do a Google search for "How to firestop your basement" from Contractor Kurt. Roxul rock wool is a good solution (also available at Home Depot). You can stuff it into the gap at the top of the wall and into the end of floor joist bays. Rock wool is much denser than fiberglass, molds kind of like clay, and stays where you put it.
I hope this is helpful.

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.

Answer: 
Yes they make a kit specifically for garage doors, or you can cut and splice it yourself for a little less money.
I used what was left of a 100' X 4' roll to insulate my sister's attic around her heat pump, and what was left over to do the garage doors. I used spray on contact cement to glue it to the garage door frame, so there would be a small air gap.

It is the air gap that provides insulation, but only if it also blocks air flow.
For instance if you have a window opening, and the window is recessed from the room. Say the opening is 4' square. If you have a air gap of 1" top and bottom, then the space between the insulation and window will get very warm, and the colder air from the room will enter this space, heat up, and blow out the top, so basically you generated a solar heater for the air. But if the air is sealed inside, it will retain the heat, and eventually the heat will flow back outside through the window.
They also sell a aluminum tape to seal the air from leaking past the insulation panels. Read Less

Rated 4.6 out of 5 by 49 reviewers.
Rated 4.0 out of 5.0 by Have to wait and see.... I see a great many applications for this product in many areas of the home and will be using it in the future. Overall this product is wonderful, excellent consistency and quality in its fabrication. Currently being used primarily in the crawlspace of the home. Wrapping over the old insulation of the ducts to tighten, seal and clean everything up. (see attached) I will also be using this product as part of an insulation and vapor barrier system I'm building for the walls. The reflective qualities of the product should also prove to be very beneficial in helping to light up the space when you do inspections or need to do any repair work under the house. My only concerns will be the long-term stability/performance of the product. Only time will tell if drying, cracking or flexibility becomes an issue but I don’t anticipate any problems.

Rated 4.0 out of 5.0 by Pole barn insulation Product arrived in a very timely manner. Very easy to work with. Only needed a few basic tools to install. We used a utility knife, straight edge, and a stapler with 1/2 inch staples. July 30, 2014
Rated 5.0 out of 5.0 by We installed this in the attic. It really works. I saw this in an attic before and wanted to install it in ours. We installed the Reflectix insulation and the attic became cooler as we progressed. It cost us an eighth ofwwhat Costco wants. All the tools we needed are a T-50 staple gun, a utility knife and a pair of large scissors. I strongly suggest buying several boxes of staples. It took us four hours with doing planning the day before. Leave a gap on either side of the roof peak vent. We used a 2 foot by 6 foot piece of 3/4 inch OSB to stand on ( one for each of us) to save us from having to stand on the ceiling joists. Our AC Guy saw it when we finished and said it will take a load off of the attic-mounted air handler. We also put in a deck in the attic to store our Christmas decorations (we have a lot) and a few other items. I went up there today when it was over 80 outside. It was the same in the attic as outside: just over 80. Saving on AC this summer and getting rid of storage will make this break even before Christmas. Oh yes....this is not a beginners project as no instructions are given. Look at the Reflectix online brochure. Study it. This is a special order item. Get it delivered to your home. April 22, 2014
Rated 5.0 out of 5.0 by 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. December 27, 2015
Rated 5.0 out of 5.0 by 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.. September 23, 2015
Rated 5.0 out of 5.0 by 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. February 16, 2012
Rated 5.0 out of 5.0 by Great stuff (and rodent proof too!) Was having issues with rodents nesting in the fiberglass insulation in the crawl space. Have pulled down that insulation under the kitchen to start and replaced it with Reflectix. Have noticed the floor is warmer, and rodents are not interested in the Reflectix at all! Have started removing the remainder of the fiberglass and am replacing with the 48" wide Reflectix. They say the R value isn't as great, but because of the radiant feature of the Reflectix, and it's ability to totally prevent air movement I"m feeling it will be better than the 12 inches of fiberglass (and my kitchen floor supports that observation!).

Rated 5.0 out of 5.0 by I'm impressed I just started installing this in my wood shop, cathedral ceiling with r19. . I have one of those electric 5500btu 240v heaters that hangs on the ceiling, set on the lowest setting to keep thing from freezing Immediately after finishing just the half of the ceiling around the heater, the room temp went from 52 to 56, and the heater hardly runs. I can't wait to finish it tonight. March 4, 2015
