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.

XPS foam board is the standard insulation underlayment for concrete. XPS provides R5 per inch and does not absorb water, which is obviously ideal for soil / concrete contact. If you have sufficient ceiling height and this is a basement installation, 2" would be best for R10. Be sure to seal all of the edges and joints carefully to block air leaks; a thick band of DAP 230 works best.

Dear ND1: Reflectix and other 'reflective insulation' products provide almost no insulation value by themselves. The R values claimed on the package depend on an 'air gap' that you must build or create when you install it, e.g. a 3/4" air gap between a hot metal roof and a sheet of Reflectix.
Under a concrete slab there will be no air gap and no radiant energy to block. The impact would be minimal. Read More

Under a concrete slab there will be no air gap and no radiant energy to block. The impact would be minimal. Reflectix claims an R value of only 1. Please look for a PDF document on the Reflectix Inc. website titled "Concrete Slab Insulation".
Home Depot sells other products that are much more effective under a concrete slab / floor, e.g. Foamular XPS foam board. XPS provides a solid R5 per inch, does not absorb water and resists water vapor transfer. Foam board is also easy to install.
Versions are also available with high compressive strength under large slabs and foundations, e.g. Foamular 400, 600 and 1000. You can order these versions through your Home Depot special order / Pro desk, if you need them.

Answer: 
BP48100 is not the product for use under a concrete slab with heating tubes. The correct product to use is the RDBW48100. This product is reflective on one side and white poly on the other. The reflective side would go down and the white side would be up. The lime in the concrete deteriorates the reflective side. That is why the white poly side would be up.

Dear Rob: Yes, but it will provide minimal benefit. All 'reflective insulation' products require you to build or create a sealed air pocket on one side to achieve the claimed R ratings. This air gap actually provides almost all of the insulation R value; the shiny bubble wrap has almost no R value. This sealed air gap would be difficult to build. Finally, reflective products have almost no value in the winter, because cold cannot be 'reflected' and warm air inside your home is not radiant.
More important, Reflectix is non-permeable; water vapor will not pass through it -- just like a poly vapor barrier. This would block the ability of your walls to dry to the outside. You should use standard house wrap instead, e.g. Tyvek, which blocks water but is permeable.
You do have a great opportunity to improve insulation for your home. You can 'wrap' the walls with XPS foam board or Roxul ComfortBoard before you install new siding. This will significantly improve the insulation value of your walls and block air leaks.
Install housewrap first, then a layer of XPS or ComfortBoard. The insulation board needs to be thick enough to prevent condensation from forming on sheathing during the winter, which could lead to rot. Here are the numbers for different parts of the country, depending on how cold your winters get:
• R-15 in climate zones 7 and 8
• R-11.25 in climate zone 6
• R-7.5 in climate zone 5
• R-3.75 in climate zone 4
When we wrapped a house in Massachusetts, we needed to use 2" thick XPS panels to achieve R10, for example. In addition to insulation, this reduces air leaks and creates an additional barrier against water infiltration. A photo is attached.
Three tips for installation:
(1) Use long deck screws to attach the foam board or ComfortBoard panels to your sheathing, e.g. Deckmate. They are corrosion resistant.
(2) Seal all of the edges and joints to block air leaks. The 'Windows and Doors' version of Great Stuff (in the blue can) works well; the cured foam remains flexible as things expand and contract, to avoid cracks. We also covered all of the joints and edges with a thick layer of DAP 230 sealant. A photo is attached.
(3) Fasten 1 x 3 strapping to the outside of the foam board / ComfortBoard, to provide an easy mounting surface for your new siding. A photo is attached.
If you are replacing your siding, you will probably need to replace window trim etc. Use Veranda PVC trim instead of wood. It never rots and never needs paint. It cuts just like wood and is easy to install. You can glue corners with AZEK trim glue; the joints are very strong and no screws are needed. Use stainless steel trim screws to install it; the 'star drive' versions are better than square drive. Fill the screw holes with a dab of DAP 230, then cover the DAP with a dot on white paint on a Q-Tip. This keeps dust from accumulating on the sticky DAP surface, and turning it gray. A photo is attached.
I hope this is helpful.

Some locations will not allow this type of insulation due to the ability of it to spread flame once the house is on fire. You can check with your local building inspectors. Read Less

Rated 4.6 out of 5 by 49 reviewers.
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 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. December 18, 2012
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!). February 7, 2012
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
