Customer Questions & Answers

air space between roof deck and product

Reflectix, In answering the question about stapling your product directly to a ceiling you said you recommend a 3/4 inch air gap minimum. However, the instructions from your web sire say 1/4 inch air gap minimum. Please resolve this discrepancy. I have read at other web sites that 3/4 inch minimum gap should be used so 3/4 inch seems like the correct answer? Thanks.
Asked by: Jim
For clarification. The application/question relates to the Double Reflective/Double Bubble product. The application of interest is for a radiant barrier in an attic. This product is not perforated (like the RB4812550) and as a result should maintain an air space between the product and the deck. The 0.25" is a "minimum", 0.75" is AOK and does not affect the performance of a radiant barrier. Radiant barriers block radiant heat transfer and do not require enclosed air spaces. Thank you for your comments.

What is the "R" value of the product

Asked by: Thaum
To Thaum and other Home Depot customers: I am puzzled by the 2016 reply from a Reflectix representative. He or she needs to read Reflectix's own documentation on R-value. First, all tests with Reflectix are done with an 'assembly' including an air gap, wall components, etc. Standard insulation products, e.g. foam, rock wool and cellulose, provide a consistent R-value per inch of thickness that does not require an assembly. Second, Reflectix and similar radiant / reflective products do not perform well in winter because cold cannot be 'reflected' and the warmer air inside your home is not radiant. See the "Reflectix Fact Sheet" available on the ReflectixInc website. With a cathedral roof and a 3/4" air gap, Reflectix claims R-7 in summer in the northern USA -- but only R-1 in winter. Third, independent tests have shown that performance steadily declines even in summer, as dust accumulates on the shiny surface. There is one application where Reflectix and similar products can boost standard insulation: in a standard ventilated attic during a hot summer. You can simply lay lay a radiant barrier down on the attic floor, over existing insulation. Independent tests show that it will reflect ~24% of the heat flux from the hot roof into the rooms below, reducing HVAC costs by 3% to 4%. This is not a replacement for standard insulation, but can provide a benefit in the summer. Plus you can shake the dust off from time to time. (This will provide no benefit in the winter.) Again, Home Depot customers should read the studies on reflective / radiant barrier products, e.g. on Fine HomeBuilding and GreenEnergyAdvisor -- to understand the difference between these products and standard insulation available from Home Depot. I hope this is helpful, Mark

I live in a metal building 30' x 40' and built 12' x12' rooms inside. The building is 15' high at center so I built the rooms with near 8' high ceilings. This leaves me with a huge attic space which is well vented. Cats and raccoons have destroyed existing ceiling insulation so I am replacing it. I have 2x6 rafters and will put fiberglass rolls between them. And to prevent more animal problems I am going to put 4' x 8' boards or rigid insulation over it. My question is "would this be a good place to put your product to keep radiant heat out of my bedroom and other rooms?" I've always had R-19 ceilings and walls but the AC still runs hard in mid-summer. Also, if I put Reflectix here, can I mount the Reflectix on panels so I can flip them or remove them in winter? Thanks.
Asked by: gcooper7
Dear GCooper7: All of that insulation in the roof would not make sense in a ventilated attic. Focus on more insulation for the FLOOR of the attic, rather than the rafters. This will save money and be more effective. Here are some suggestions: (1) Make sure every air leak into your attic is sealed -- e.g. around recessed lights, pipes, wiring, etc.; this is almost as important as insulation. Recessed ceiling lights are culprit #1: install Tenmat covers and seal the edges with DAP 230 sealant. The 'Window and Door' version of Great Stuff spray foam is good to fill larger gaps and holes -- but do not use it near anything that gets hot, e.g. a chimney or exhaust vent. For gaps near a hot exhaust vent, fill the space with Roxul rock wool, then cover it with fire resistant sealant. For the large gap next to an interior chimney, cover the gap with aluminum flashing (available at Home Depot) nailed to the joists, and seal the edges with 3M fire resistant sealant. See: Tenmat Model # FF130E Home Depot Internet # 204286308 Store SKU # 1000012747 DAP 230 sealant, Home Depot Internet #100035980 Store SKU #284425 Great Stuff 'Window and Door' spray foam, Model # 99053990, Home Depot Internet #206983874 Store SKU #1001869291 Roxul rock wool insulation, Model # RXCB351525 Internet #202090820 Store SKU #974419 3M fire resistant sealant, Model CP-25WB+, Home Depot Internet #100166701 Store SKU #163096 (2) Make sure your floor / ceiling joist bays are filled with insulation. Roxul rock wool or cellulose are more effective than fiberglass. (3) Install foam board on top of the ceiling joists, over the insulation in the bays. This will add R-5 per inch of thickness, break the 'thermal bridges' created by all of the (previously) exposed wood joists, and help you improve the air seal. Use Dow Super Tuff-R, which provides R-13 plus foil facing on one side that should face the roof as a radiant barrier. See: Super Tuff-R Model # 99060464, Home Depot Internet #300528092 Store SKU #1002215973. If you live in an area with hot summers and/or cold winters, install a double layer for R-26. Again, carefully seal all of the joints and edges to block air leaks, with DAP 230 sealant and the 'Window and Door' version of Great Stuff foam. (If you install a double layer - a good idea - run the second layer 90 degrees from the orientation of the first, and seal it carefully to block air leaks.) Independent tests have shown that a radiant barrier on the floor of a ventilated attic is superior and more cost effective than one mounted on the rafters. The foil facing on Super Tuff-R will take care of this -- and nothing will be needed for the roof. Also improve the seals into your attic to block cats, raccoons, rats, mice, etc. Use metal grating to cover ventilation holes. Steel wool will stop mice and rats, which can sneak through gaps as small as 1/4" I hope this is helpful. Mark

What's the difference between this roll & the more expensive roll of the same size?

This roll has the staple tab and is cheaper than your other roll of the same specifications: What's the difference? Does the more expensive one have a greater R-Value?
Asked by: Bianca
Dear Bianca: One important clarification. Both versions have very little R-value by themselves -- just R-1. Why? The claims on the package are based on a sealed air gap that you must build / create when you install it. This air gap provides almost all of the claimed R value. In addition, Reflectix and similar radiant / reflective barrier products are not effective in winter because cold cannot be 'reflected' and the warmer air inside your home is not radiant. For example, Reflectix claims R-7 under a hot cathedral ceiling in the summer (with an air gap), but only R-1 in winter in the northern USA. So read the installation guides carefully, and seal the edges and joints carefully when you install it -- to avoid air leaks. You will also find that standard insulation products sold at Home Depot are always more effective for walls, roofs, basements, garages, etc. Foam board provides solid R-5 per inch of thickness and rock wool provides R-4 per inch of thickness, for example - winter and summer. If you fill a standard 2x4 wall with either foam board or Roxul, you will add R-12 to R-15, far more than Reflectix can provide. See: Tuff-R Model # 193829, Home Depot Internet #100322375 Store SKU #163524 and Roxul ComfortBatt Model # RXCB351525, Home Depot Internet #202090820 Store SKU #974419 There is only one exception: in a standard ventilated attic, a reflective barrier laid down on the floor will reduce heat from a hot roof in the summer by ~24%, which will cut air conditioning bills by 3% to 4% on average, according to an independent study. I hope this is helpful, Mark

24 in. x 100 ft. Double Reflective Insulation with Staple Tab is rated 4.5 out of 5 by 11.
Rated 5 out of 5 by from This Reflective Insulation is great to work with. It bends around obstacles and corners, is light weight and Class "A" Fire Rated. It goes on easy with an air operated staple gun and fast. It can be cut with a good pair of scissors.

Rated 5 out of 5 by from Worked liked a charm. Better than expected! I created an office/workshop in a large storage building. The building is basically 2x4 and 2x6 framing covered with thin aluminum siding and roofing panels. In the afternoons when the sun shines on the building, it heats up like an oven and the window A/C unit just could not cool it. I purchased 2 rolls of the reflective insulation with staple tabs and installed between the studs and against the metal siding. The insulation has worked even better than I expected in reducing the radiant heat produced by the sun on the siding. My A/C unit can now cool the building nicely!

Rated 5 out of 5 by from So much easier than other insulation! I was leery about this insulation but it is incredibly easy to install and very efficient at insulating my shed. When the product arrived it didn't appear to be the "staple tab" version. However, after contacting the manufacturer I discovered that the difference between the two versions is very minimal. The staple tab version edges are perforated to pierce the bubbles in the material. This flattening of the edges allows not only easier installation but it seems to allow for a tighter fit to the studs. Take my word for it, use this over other forms of insulation!

Rated 5 out of 5 by from Good quality, easy to install It's working as advertised, now I just need to install some insulation behind it.

Rated 5 out of 5 by from Good for TIs who need shielding in the house. Cuts easily with scissors, is flexible but also will stand by itself on edge if put on its side edge.

Rated 5 out of 5 by from So Easy and So Effective A great product! My old fiberglass insulation was getting lived in by rats and ripped apart. I could replace and seal the entire crawl space simply, easily, and without that nasty fiberglass! What a great product. I want to use it on everything!!!
Date published: 2014-01-15
Rated 5 out of 5 by from Works Great We had enough to cover about a third of our ceiling. When I checked the part of the roof that did not have the product installed on it the temperature was around 120F. Then I checked a part that was covered and the temp was around 95F. So this stuff is working.
