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

Is this insulation good for outdoor use I can't find anyone that sells Reflectix Model# CDW4850 & Butyl foil tape for outdoor use

For a hot roof application (radiant barrier), sealing the seams is not necessary. Respectfully, the responder from Mass. is in error. His statement is confusing two applications, radiant barriers and reflective insulations. 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. Reflective insulation is tested in the same manner as fiberglass and foam products, and in wall and floor systems, provides a year around R-value benefit.

Correction Necessary – per the comment from the “ReflectixTechnicalGroup” – this application provides the highest level of benefit with a spacer installation. Please refer to the June 3, 2016 response from the Reflectix Customer Service - thank you. Reflectix Technical Group

Dear Ice and other Home Depot customers: The new reply from someone in the Reflectix Technical Group is curious. He / she stated: "Respectfully, the responder from Mass. is in error.

Reflective insulation is tested in the same manner as fiberglass and foam products, and in wall and floor systems, provides a year around R-value benefit." First, commercial metal buildings typically do not have an enclosed and ventilated attic, like a house. So Ice would need to install Reflectix under the metal roof, with a sealed air gap. Second, Reflectix is NOT tested in the same manner as fiberglass and foam insulation. You can see this on the Home Depot website. Fiberglass, foam board and other standard insulation products are tested as materials, with an R value per inch of thickness -- e.g. R-13 for 3.5" of Owens Corning fiberglass, and R-5 per inch with Foamular foam board. Reflectix is always tested as part of an assembly, e.g. a simulated wall with 2x4 studs, dry wall, an air space and layer of Reflectix. Why? Because the shiny bubble wrap that Reflectix is made from has very little R value -- only R-1. The sealed air gap that you must build / create provides almost all of the claimed R values, not the bubble wrap by itself. Third, the performance of Reflectix and other radiant barriers varies with the temperature -- better in summer and poor in winter. In a cathedral ceiling, for example, Reflectix claims R7 in summer but only R1 in winter in the northern USA. Why? Because cold cannot be 'reflected' and warmer air inside your home does not create much infrared (radiant) energy. Reflectix should provide ASTM test reports that show R-value performance in summer AND winter temperatures for each assembly, and post these reports on their website. I look forward to more detailed information from the Reflectix Technical Group. Mark

Thank you for your question. Duct insulation is a very prevalent application for our product. Either Reflectix Foil Tape or an HVAC Foil Duct tape with an acrylic adhesive will work for your purpose. Please refer to the product webpage - then to the "Info and Guides" box a little lower to the right on the page - click on "Installation Guide" - the Duct Application is listed and will provide you the additional instructions that you require.

First, a radiant barrier is the key part of reflective insulation, e.g. the shiny aluminum surface on Reflectix bubble wrap. This is a distinction without a difference.

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.

Dear Cats and other Home Depot customers: The new reply from someone in the Reflectix Technical Group is curious. He / she stated: "Respectfully, the responder from Mass. is in error. Reflectix wall and floor assembly R-values are valid year around (we state specific thermal performance “per application”). Our products are tested in the same manner as fiberglass and foam." First, Reflectix is NOT tested in the same manner as fiberglass and foam insulation. You can see this on the Home Depot website. Fiberglass and foam board are tested as materials, with an R value per inch of thickness -- e.g. R-13 for 3.5" of Owens Corning fiberglass, and R-5 per inch with Foamular foam board.

This is why I recommended standard insulation for Cats' mobile home. I look forward to more detailed information from the Reflectix Technical Group. Mark

Dear Petaluma2015: The new reply from someone in the Reflectix Technical Group is curious. First, Reflectix is NOT tested in the same manner as fiberglass and foam insulation. You can see this on the Home Depot website. Fiberglass and foam board are tested as materials, with an R value per inch of thickness -- e.g. R-13 for 3.5" of Owens Corning fiberglass, R-5 per inch with Foamular foam board and R-4 per inch for Roxul rock wool. Reflectix is always tested as part of an assembly, e.g. a simulated wall with 2x4 studs, dry wall, an air space and a layer of Reflectix. Why? Because the shiny bubble wrap that Reflectix is made from has very little R value -- only R-1. The sealed air gap that you must build / create provides almost all of the claimed R values, not the bubble wrap by itself. Second, the performance of Reflectix and other radiant barriers varies with the temperature -- better in summer and poor in winter. In a cathedral ceiling, for example, Reflectix claims R7 in summer but only R1 in winter in the northern USA. Why? In the summer, the shiny surface of Reflectix can reflect radiant (infrared) heat from the hot roof. In winter, cold cannot be 'reflected' and warmer air inside does not create much infrared (radiant) energy. Reflectix should provide ASTM test reports that show R-value performance in summer AND winter temperatures for each assembly, and post these reports on their website. I look forward to more detailed information from the Reflectix Technical Group. How did your patio insulation project go? Mark
