Dear Joe1222: Reflectix no long claims any R value for attic installations -- only cathedral ceilings. For more info look for the Federal Trade Commission Fact Sheet on the Reflectix Inc. website.
Home Depot sells a number of insulation products that would be more effective in your attic, that you could install yourself, e.g. blown in cellulose, XPS foam board and polyiso foam board. The best option depends on the configuration and accessibility of your attic.
The hose used for blown in cellulose, for example, can extend into nooks and crannies in a complex attic that are difficult to reach. If you have a simpler open attic, foam board will be more effective -- particularly if you do a good job sealing all of the joints and edges to block air leaks. If you have a large attic that you would like to use for storage, or an HVAC system and ducts in your attic, foam board is great option because you can seal the attic when you install the foam board -- and turn it into conditioned space. This will significantly reduce the temperature in the attic, and make your HVAC system more efficient.
Note: Foam board must be covered by a thermal barrier if the attic is used for storage. We typically install drywall, but it is cheaper and easier to spray intumescent paint. Look for Forcefield FireGuard, Home Depot Model # FFGD E84-g05 Internet # 203582028

Shouldn't be any moisture issues. A lot of the radiant barrier comes sized to fit in between attic beams. Measure the distance between the beams and buy accordingly. Because mine were spaced out far I had to buy the widest role I could find and just started on the low side and overlapped the tops. I didn't even use tape on the overlapped areas and it's great.

Dear Ann: As the Reflectix rep noted, either tool will work. Please also read the installation directions on the Reflectix website, particularly if you plan to install Reflectix on top of your roof vs underneath. All reflective insulation products require you to build / create a sealed air pocket on one side. This air gap provides almost all of the claimed R value. The shiny plastic has almost no R value. It would obviously be impossible to create a sealed air gap on top of your roof -- so this would provide very little insulation value. The correct place to install Reflectix is on the rafters in your attic, with a sealed air gap under the roof deck. Use sealant on all of the edges and joints to block air leaks.

Also note that reflective insulation is not effective in winter, because cold cannot be 'reflected' and warm air is not radiant.

If you are replacing your roofing this is the perfect time to add insulation, XPS foam board is the best option. XPS provides R5 per inch, winter and summer -- and does not absorb water, which is essential for roof appliactions. Start with 2" XPS: Owens Corning Model # 52DD, Home Depot Internet # 202085962 Store SKU # 307101

I hope this is helpful.

Dear AJ: In addition to the requirement for an air gap, this air space must be sealed to prevent leaks. Also note that reflective / radiant barriers are not effecting in winter because cold cannot be 'reflected' and warm air is not radiant. So if you are trying to keep cold in or out, use standard insulation.

Depending on your application, also be aware of the maximum service temperature of 180

So if you are trying to keep cold in or out, use standard insulation.

Depending on your application, also be aware of the maximum service temperature of 180 degrees. Reflectix is made from plastic with a very thin aluminum coating, and will melt or burn. This is also true for foam board. So if you are trying to insulate a hot container of some kind, use Roxul ComfortBoard which provides R4 per inch, and is fire resistant.

I hope this is helpful.

It provides almost no insulation R value itself; the claims on the package are based on a sealed 'air gap' that you must create or build.

Dear TeaRose: Reflectix is not a good solution to insulate your well house wall. It provides almost no insulation R value itself; the claims on the package are based on a sealed 'air gap' that you must create or build. Reflectix is also ineffective in winter, even with an air gap. There is no radiant heat for the shiny surface to reflect.
The most effective solution for your well house would be XPS foam, with a reliable R value of 5 per inch. XPS does not absorb water, so it is good for at-grade installations. A few suggestions:
(1) Focus on insulating and sealing the lid / cover, to isolate the well house from cold winter temperatures. Attached 4 inches of XPS foam board to the underside of the lid (two 2" layers), and improve the air seal if needed.
(2) Depending on your winter temperatures, you may also need to insulate around the top of the well house, to isolate the concrete structure and steel wall. XPS is good for this as well.
(3) Insulate the top 4' of the well house wall, but not the bottom 2' -- which will be warmed by the relatively constant temperature of the surrounding earth at that depth.
(4) Insulate the top 4' with 1/4" Foamular which can bend to match the curve of the well house wall. Look for Model # 10UM Internet # 100320301 Store SKU # 409692. Apply multiple layers to build up a thickness of 1" to 2".
(5) Use Loctite Powergrab Heavy Duty Construction Adhesive to glue the Foamular to the galvanized steel wall, Model # 1589155 Internet # 203009256 Store SKU # 281979
I hope this is helpful.

Answer: 
Yes you can use Reflectix insulation to insulate the well house. The R-value would be R 3. The main concern is how to install the insulation. It needs to be installed with an air space between the interior wall and the Reflectix. Without more information I cannot help with the installation.

Rated 4.4 out of 5 by 9 reviewers.
Rated 5.0 out of 5.0 by Good buy I have installed this insulation before - under the roof of a house and now as a house-wrap. I have found it very easy to work with. It reduced the heat in my attics & upstairs significantly. A caution: if you are using this on a roof, you will need to wear long-sleeves, long pants, and sunglasses. It reflects both the light and the heat quite efficiently, which puts you in a solar-oven situation. Timing your work for hours when the sun is low in the sky is your best bet. July 7, 2014
Rated 5.0 out of 5.0 by I love it! Installed it on the inside of my roof which has no isolation like a cabin. This layer traps all the heat that would usually fill the house. I don't need to tarp my roof anymore. August 5, 2014
Rated 5.0 out of 5.0 by Reflective insulation The installation of the reflective insulation was easier than advertised April 14, 2015
Rated 3.0 out of 5.0 by Works as advertised The insulation works as advertised but the length of the roll that I purchased was 98 ft.not 100 ft. as advertised.I needed exactly ten 10 ft. sections for my project and when I reached the end of the roll the last piece was only 8 ft.long. June 24, 2014
Rated 5.0 out of 5.0 by Very good product. Covered an entire basement ceiling (875 square feet) with this - was very easy to work with - in some places had to cut around pipes, etc. - it was easy to cut and then staple in place. Easy installation, looks great - will see how well it actually helps to insulate now that it is installed. March 4, 2014

We put it directly on the inside of the tin and on the inside of the tin roof. Immediate noticeable temp change. Worth every penny for the savings of electricity in for Texas summer August 21, 2013
