16 in. x 25 ft. Double Reflective Insulation Roll with Staple Tab Edge

Dear Fish: Reflectix and similar reflective / radiant barrier products will make zero difference on your refrigerator. Cold cannot be 'reflected' and the warmer air inside your home is not 'radiant'. Don't try to insulate your refrigerator with other insulation products. Refrigerators are heat pumps that basically transfer warm air (inside) to the cooler air (outside). They need open air circulation to function efficiently. The only option to improve the performance of your refrigerator is -- a new refrigerator. Compare the 'Energy Star' ratings for refrigerators with the same capacity. I hope this is helpful. Mark

No, but very easy to install - go to the Reflectix website or phone them for help. Their website is: reflectixinc.com

Dear BigE: That depends on the type of insulation you need -- e.g. hot summer sun and/or cold winters. Reflective / radiant barriers do not work in the winter because cold cannot be 'reflected' and the warmer air inside your shed is not radiant. If you want to insulat your metal shed against the summer sun, a reflective / radiant barrier can be helpful, but you need to create a sealed ~1"air gap between the metal sheet and the radiant barrier. Plus the air gap needs an entrance for cooler air and an exit for hot air, e.g. a vent at the bottom and top of the walls, and at the bottom and ridge of the roof. Make sure the reflective layer is carefully sealed to prevent air leaks into your shed. This will block infrared heat. You will still need, however, standard insulation for the interior walls. For example, build 2x wood walls inside your shed, and fill the stud and rafter bays with rock wool, which provides R-4.1 per inch of thickness. Also insulate the floor and door with foam board or rock wool, and make sure the door has a good seal around the edges. I hope this is helpful. Mark

Dear Ed: Reflectix and similar reflective / radiant barriers will make almost no difference on your garage door. They provide very little insulation value by themselves -- just R-1. Plus reflective / radiant barriers do not work during the winter because cold cannot be 'reflected' and the warmer air inside your garage is not radiant. Home Depot sells another product that is easy to install and delivers R-8 insulation performance: Owens Corning model GD01, Home Depot Internet #202257272, UPC Code # 047563700275 Store SKU #744925 This product also works winter and summer. I hope this is helpful. Mark

Dear Ddubba: No. Reflectix and similar reflective / radiant barrier products provide only R-1 by themselves. The claims on the package are based on a sealed air gap you must build when you install it. You cannot simply wrap it around your inflatable hot tub. Second, reflective / radiant barrier products do not work in the winter because cold cannot be 'relfected' and warmer air, e.g. in the inflatable part of your hot tub, is not radiant. The only way to reduce the electric bill for your inflatable hot tub would be to build a light frame around it, filled with standard insulation, e.g. rock wool batts. You should also insulate the space between the inflatable and the ground under it, e.g. with 2" Foamular 250 foam board. Plus you need a well-insulated lid / cover that seals out cold air. I hope this is helpful, Mark

Dear Leo: Definitely not Reflectix -- which delivers only R-1 by itself. You must build a sealed 1" air gap to achieve the claimed R-value on the package and marketing materials. This is clearly not possible with PEX pipe. Home Depot sells pipe insulation that is effective. You can also add multiple layers to boost the total R-value. For example see:Armacell Model # HST07812, Home Depot Internet #100585113, UPC Code # 803014116220 Store SKU #420390 Although this product is supposed to 'self seal', it is a good idea to reinforce the adhesive with a strip of foil HVAC tape. This adds R-3.3 If you want to add more insulation, wrap the Armacell with a fiberglass pipe sleeve, where the inside diamter matches the outer diameter of the foam. For example: Model # F15XAD, Home Depot Internet #100162619, UPC Code # 077578018379 Store SKU #170795 Seal the seam and joints / ends with foil HVAC tape. This adds R-3 for a total of R-6. I hope this is helpful. Mark

2 layer will not help, but a good air-gap will. Just look at your windows air-gap. It is the same principle.

Laura, Yes you can I will tell you that our product is not meant to be exposed to the elements. If the deck is not enclosed the product may eventually break down over time and need replaced.

Dear Meeks: Save your money. Reflectix and similar reflective / radiant barriers provide almost no insulation by themselves -- just R-1. The claims on the package are based on a sealed air space you must build; this sealed air gap is responisble for almost all of the claimed R-value. So stapline Reflectxi to your garage walls will achieve amost nothing in terms of insulation. Real insulation is the only practical and effective option. Home Depot sells foam board and rock wool. for example, which are good for walls. Blown cellulose is good for attics, if you have one above your garage. If your garage walls are concrete block, you will need to build 2x4 walls inside to contain and cover the insulation. If you already have interior walls with drywall, you will need to remove the drywall to fill the stud bays with effective insulation. Garages are notoriously poorly insulalated. Read-up on insulation on the Web. Fine Homebuilding is a good source. I hope this is helpful. Mark

Dear Gunslinger: Reflectix was required by the FTC to publish a 'fact sheet' listing the actual R-value for various installations. A copy is available on their website. Here is what it says about a cathedral ceiling: Cathedral Ceiling (Southern US) 1 One Air Space 0.75” between the product and the top of the fiberglass R-6.0 Summer (down) R-2.0 Winter (up) Cathedral Ceiling (Northern US) 1 One Air Space 0.75” between the product and the inside of the ceiling sheathing (sheetrock) R-7.0 Summer (down) R-1.0 Winter (up) They do not provide a certified R-value for two layers, but you can see two key factors: (1) The R-value depends on a sealed air gap, which provides most of the benefit. (2) Reflective barriers like Reflectix do not perform well in the winter, because there is no 'radiant energy' to reflect, and cold cannot be relfected. In short, standard insulation provides superior performance, winter and summer, e.g. blown cellulose, rock wool and fiberglass. All three are sold by Home Depot and can be installed by the average homeowner. Read up on the details for installation; there are many good articlea on the Web, e.g. from Fine Homebuilding and Green Building Advisor. There is one application where a radiant barrier like Reflectix will provide a unique benefit: in a standard ventilated attic on hot summer days. If you simply lay a radiant barrier down on your attic floor, over whatever insulation is there, it will reflect ~24% of the heat flux from the roof into rooms below, and reduce your HVAC costs by 3 to 4%. You will need to shake the dust off the reflective barrier every few years, which sharply reduces reflectivity. This does not eliminate the need to insulate your attic with standard insulation, of course. The best option for a standard ventilated attic is blown cellulose, which is relatively easy to install on your attic floor over whatever insulation is already there. Home Depot rents blowers to install cellulose. I hope this is helpful. Mark
