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
Respectfully, the responder from Mass. is in error. Reflective insulation assemblies are constructed with an enclosed air space and a high reflectance/low emittance surface facing the air space. If the enclosed air space did not have the high reflectance/low emittance surface, the tested R-value would be significantly lower. Reflective insulation assemblies are installed in cavities that have enclosed air spaces and provide stated R-value benefits. These assemblies are tested in the same manner as fiberglass and foam products, and in wall and floor systems, provides a year around R-value benefit.

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

can this be used in a storage shed?

we are trying to make our storage shed livable and need to insulate ceiling and walls
Asked by: vkrose
Dear VKrose: Reflective insulation is not the most effective insulation product in summer, and does not work in winter. So your money would be better spent on standard insulation, particularly if you will need to heat your shed in winter -- e.g. foam board or rock wool. Foam board is the most effective with R5 per inch. You can cut pieces to fill the space between your rafters and studs. Be sure to carefully seal all of the edges and joints to block air leaks. The 'Windows and Doors' version of Great Stuff foam works well; the cured foam remains flexible to avoid cracks as things expand and contract. We recently completed a deep home remodel project along the shore in Massachusetts and used this technique. A photo is attached. Foam board is also flammable, however, and MUST be covered by an approved 'thermal barrier'. The standard is 1/2" drywall. So if you plan to finish the interior of your shed, this is a good option. If the appearance of the interior walls is not a concern, Roxul ComfortBatt and ComfortBoard are the best options - with R4 per inch. Roxul is much denser than fiberglass and inhibits air flow, and is not flammable. If you live in a climate with extreme temperatures, it would be a good idea to finish your insulation with a layer over the top of the rafters and studs. This breaks the 'thermal bridge' created by the wood framing, which is a surprisingly good conductor of heat / cold. I hope this detail is helpful, and best of luck with your project. 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.
Date published: 2014-04-15
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.
