Answer: 
Depending on where the product is installed - there are two types of benefits. Radiant barriers are installed in open attics (typically ventilated) and do not require enclosed air spaces. This type of application reduces radiant heat transfer and is not quantified with an R-value. Reflective insulation assemblies are installed in cavities that have enclosed air spaces and provide stated R-value benefits. Read More

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.

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.

Answer: 
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.

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.

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

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.

Dear Bill: Yes, all of the reflective bubble wrap "insulation" products are virtually identical -- basically poly bubble wrap with a very thin and shiny aluminum surface on one or both sides.
A couple of caveats for your garage wall application: (1) Reflectix and Ecofoil have almost no insulation R value themselves. The R values claimed on the package are based on a sealed 'air gap' that you must create or build, e.g. by stapling the product midway between your studs. (2) Reflectix and Ecofoil are not effective in winter; there is no radiant heat to reflect. 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 garage, winter and summer, e.g. foam board, fiberglass batts and Roxul rock wool batts. Depending on your climate and how well you want to insulate your garage, the best option would be to fill the stud bays with Roxul, then cover the studs with a continuous sheet of 1" or 2" XPS, to break the thermal bridge to the studs. XPS must be covered with a thermal barrier, e.g. drywall or intumescent paint. See: Forcefield FireGuard, Home Depot Model # FFGD E84-g05 Internet # 203582028

Our product is comparable to Ecofoil. Reflectix does not have the same fire rating as sheet rock. Reflectix has a class A/class 1 fire rating but it will burn. It is not fire proof nor flame retardant. You can apply Reflectix to the interior stud wall in a garage. You would recess the Reflectix between the studs so there would be air space between the product and the outside wall and the interior wall Read More

48 in. x 100 ft. Double Reflective Insulation with Staple Tab is rated 4.5 out of 5 by 9.
Rated 5 out of 5 by from Helped make our Texas shed 10 degrees cooler Used this product to retrofit an enclosure on a pole barn to make it livable. 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

Rated 5 out of 5 by from 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.
