Dear 1938: "Reflective insulation" is particularly ineffective in cold temperatures. Check the "FTC Fact Sheet" on the Reflectix web site. For example, they claim the R value for cathedral ceilings (with an air gap) is 7 in summer -- but only 1 in winter. This is because the shiny surface reflects infrared radiation in summer, e.g. from a hot roof or garage door -- which is not a factor in Read More
Dear 1938: "Reflective insulation" is particularly ineffective in cold temperatures. Check the "FTC Fact Sheet" on the Reflectix web site. For example, they claim the R value for cathedral ceilings (with an air gap) is 7 in summer -- but only 1 in winter. This is because the shiny surface reflects infrared radiation in summer, e.g. from a hot roof or garage door -- which is not a factor in winter.
Fundamentally, "reflective insulation" has virtually no insulation value itself; all of the R values claimed by Reflectix are based on an "assembly" with an air gap and ideal conditions. If you apply Reflectix to a surface without an air gap, e.g. a garage door, the R value is only 1. If you double-up with two layers, the R value is ~2. In short, very little insulation value for the time and money.
Garage doors are difficult to insulate, with all of the movement and vibration. Standard foam board is flammable and cannot be used unless it is covered with special intumescent paint.
The best option would be rock wool panels, which are light and solid like foam board -- but non flammable. Roxul is one manufacturer; their ROCKBOARD® 40/60/80 is available with a foil or white poly surface for a more finished look. This product provides a consistent R4 / inch insulation value, year round. Use 1 or 2 inch thick panels, depending on the level of insulation you want to achieve. Even though Home Depot doesn't carry this product on their shelves, you can order it from your store's Special Order desk. (Builders often purchase products via the Special Order desk.)
You could install it yourself without special tools. You can cut Roxul Rock Board with a sharp knife; Home Depot also sells a special knife for cutting insulation panels that works well. The panels can be mounted to your garage door with standard screws; also run thick beads of heavy duty construction adhesive around the perimeter and in lines across the back. The screws will hold the panels in place while the adhesive dries. Home Depot carries Loctite and Liquid Nails adhesive, e.g. Liquid Nails Model # LN-901 Internet # 202203994.
You should also make sure your garage door is air sealed as effectively as possible, Home Depot sells weatherstrip products for the top, sides and bottom.
If the temperature in your garage is an issue, have you also insulated the roof? XPS foam board is a good option.
I hope this is helpful.

Dear 1938:

Dear 1938:
I just answered this question for another HD customer, and I wish I had saved the text! In short, "reflective" insulation is not effective for garage doors and most other applications. Do a Google search for "Stay Away from Foil-Faced Bubble Wrap" by Martin Holladay, an industry expert. You can find a number of other articles, including an independent study by the Canadian government.
If you check the Reflectix website, for example, look for the "Literature" tab and the "Federal Trade Commission Fact Sheet" at the top of the page. They claim R3 performance for garage doors, with "One open air space on the exterior side of the product." This is a tip-off. Reflective insulation has minimal (~R1) insulation value in itself; the claims are based on an "assembly" and the air trapped behind. And as dust gathers on the reflective surface, performance drops further.
Garage doors are difficult to insulate. Standard foam board from Home Depot cannot be used, because it requires a thermal barrier in occupied space. This is simple with walls and cathedral ceilings; just cover it with drywall. For garage doors the best option is insulation board made from mineral wool, which is light, easy to install and non-flammable. Attach and seal the mineral wool panels to the garage door with a perimeter bead of construction adhesive, and hold them in place with a few long screws while the glue cures. This provides reliable R value of 4 per inch. With 2" panels, you could achieve R8, winter and summer. Panels are available with a foil surface on one side, which would be good for a garage.
Certainteed and Roxul are two suppliers. You can order products like these through the Home Depot Customer Service / Pro Desk -- they can deliver a wide range of building products that are not on the store shelves. We recently order special PVC trim and decking for a project on the shore in Massachusetts, for example. The Home Depot Customer Service / Pro Desk staff are typically very experienced and can help with product selection.
I hope this is helpful.

Another consideration is the adhesive. I used Loctite PL375 to glue it to the steel door panel. I think that will work to add a second layer but I'll do a row of the panels and see how that holds up before doing the entire door again. It went up pretty easy, just measure, cut, squeeze the Loctite around the edges and two rectangles in the middle. I think I used about 6 tubes of Loctite for a 2 car steel door. Read Less

Answer: 
Thank you for your question. Year around performance includes an R-3.0. The benefit is derived from the system created with our product in conjunction with an air space. If our product is doubled, side by side, the additional benefit is an R-1.1.

Reflective insulation over the slated ceiling

This question is from 24 in. x 100 ft. Double Reflective Insulation
Asked by
Boston, Mass
Read all my Q&A
September 22, 2015
One of my bedrooms located directly under the roof - no chimney. Construction is about 50 years old and apparently original insulation was not good - the room is cold during the winter and even bigger problem - hot over the summer when sun heats the roof. It's a town house, so I cannot do anything on the structure outside - only inside my bedroom. So I decided to staple (or glue) reflective insulation roll over my ceiling from inside and then glue over reflective foil barrier styrofoam ceiling panels 20" by 20" ( the are very lightweight and good looking). My question is - will this installation of the reflective barrier over the ceiling help little bit to prevent heat from sun coming from the roof down to ceiling and heat up the air inside or it just a waste of money? I also hope that reflective barrier on the ceiling will keep room warmer in the winter by reflecting some heat inside coming out. I will appreciate professional opinion.

Dear Alden: The Reflectix rep just replied and referenced installations in a crawl space as somehow equivalent to a ceiling or attic, with links to the crawlspace installation documents on the Reflectix website. Two notes:
(1) A crawlspace and ceiling / attic are very different from an insulation and heat transfer perspective. In a crawlspace, you are trying to block the movement of cold air up into the warm house, and the ability of cold air to contact and chill the floor. In a ceiling / attic, Reflectix can block radiant heat from a hot roof. So, the R values quoted for a crawl space do not apply to a ceiling.
(2) Reflectix Inc. does not offer installation guides for a standard ceiling, only a cathedral ceiling -- and makes no R value claims for a standard ceiling or attic.
I hope this clarification is helpful.

Dear Alden: Your bedroom sounds like our home -- built around 1953 with little - if any - insulation.

The R values claimed on the package depend on a sealed 'air gap' that you must build / create when you install it. If you staple or glue Reflectix to your ceiling, there will be no impact -- except on your wallet. Look for the "Federal Trade Commission Fact Sheet" on the Reflectix Inc. website for details.
(2) Reflectix and other "reflective insulation" are not effective in winter because there is little radiant energy to reflect off the shiny surface. In a cathedral ceiling, for example, Reflectix claims R7 in summer in the northern US, but only R1 in winter. Reflectix does not make any claims for attics or ceilings.
(3) Foil-faced foam board is an effective type of insulation with an R value of ~4 per inch. It is flammable, however, and must be covered by a thermal barrier in occupied space like your bedroom., e.g. drywall or intumescent paint.
Unfortunately, there are no effective insulation options for your ceiling. You would need to install better insulation in the attic, e.g. blown cellulose, rock wool, fiberglass or foam board.
My apologies for this unfortunate news.

We appreciate your interest in Reflectix products. In all of our applications – the product requires an “enclosed air space” to provide an R-value benefit. Although you working with a roof assembly, 2 crawl space applications are applicable:
http://www.reflectixinc.com/basepage.asp?PageName=DIY+Crawl+Space+%2D+R%2D16&PageIndex=541
http://www.reflectixinc.com/basepage.asp?PageName=DIY+Crawl+Space+%2D+R%2D21&PageIndex=787
With a single sheet installation (up inside the cavity) the benefit is proportional to the “enclosed air space” – examples:
Benefits based on air space height above or below product:
• 0.5” air space = R-2.7
• 0.75” air space = R-4.6
• 3.5” air space = R-8.2
The reduction in heat transfer will be related to the R-value you build into the system.

Dear Chloe: One more note -- if your garage door is a "roll up" with multiple hinged panels, it would be very difficult to create sealed air pockets behind each panel for "reflective insulation". Without an air pocket, the R value is only 1, best case, with no dust.

Rated 4.6 out of 5 by 36 reviewers.
Rated 5.0 out of 5.0 by Easy to install I still have to see how well this helps my garage in the winter but installation was easy. I have a single, two car garage door. I measured and cut each panel, then used Loctite PL375 to glue it to the sections. I didn't have to make any adjustments to the garage door opener and I have a good amount of the insulation left over for something else. I may consider adding another layer or using it in the attic. My garage is part of the house but not heated. I'm hoping to at least keep it above freezing this January. The bedrooms above the garage get pretty cold, especially the floors. The finished look is definitely better than the plain steel panels. I think it's quieter in there too, I don't hear the cars passing by any more. November 1, 2014
Rated 5.0 out of 5.0 by Works really well on garage door! I installed the Reflectix radiant barrier foil on the inside panels of a double and a single garage door. I installed these by using not only double-sided tape but also by securing the foil sheets with the existing door panel hinges. The installation worked out really well. Now, when the outside of the garage doors measures a hot 102 deg F on a sunny day, the inside of the same doors stays at about 70 deg F. Wow! What a difference it makes. Now it is almost the end of October in Austin, TX, and outside it is quite a bit cooler than what we see in summer. I am waiting to measure the temperature differential on a hot summer day. Home Depot did an excellent job in shipping the foil quickly and also charging for it very reasonably. October 22, 2013
Rated 5.0 out of 5.0 by So easy to work with. I installed this product all by myself on the inside of my garage doors. It took me about 2 hours to measure, cut the pieces and install in the doors. Really looking forward to seeing how well it helps reduce the very hot AZ temps in my garage and by extension the inside of my house in the next couple of months. It was totally painless to install. :) May 6, 2014
Rated 5.0 out of 5.0 by Easy to use product for Garage Door Insulation I used this to cover the inside of my 2 car and 1 car garage doors on my 3 car garage. These doors are aluminum and face the west. They really heated up in the summer making the garage extra hot. I followed the garage door installation video on the manufacturer's website and the installation turned out great. The 100 foot roll weighs 10 pounds, so the weight on the garage doors was about 6 (on the double) and 4 pounds (on the single door). I tested opening both door by hand and didn't notice any difference in the extra weight on them - so I didn't need to adjust the springs. Overall, it was a very easy installation. I used 1" wide double-sided carpet tape to attach it after cleaning the rails and styles with denatured alcohol to make it stuck really well. The garage temperature is much better, the room doesn't echo as much, and it brighter due to the reflection off the doors. It also cut down on some of the rattling sounds when the doors open and close. If you live in a hot area, I would recommend this on any south or west facing metal doors. October 15, 2013
Rated 3.0 out of 5.0 by onky ine problem... The manufacturer intentionally mad the even the biggest roll one panel shy for a 2 car garage door, forcing u to buy a small roll to finiah the job June 14, 2015
Rated 5.0 out of 5.0 by Easy choice to insulate garage doors This is a great product to help control the climate in a garage. It was simple to cut to size for the garage door panels. For now I just have it pressed into place (cut it slightly larger on the height) using the lips of the metal garage door. The roll was large enough to do a two car and 1 car garage door with some left over and took about 30 minutes. It's already making a huge difference in temperature from the radiant heat of the sun on the door and this will definitely help the room above it not get so warm. I highly recommend this product for insulating a garage door. This will definitely pay for itself in a matter of months. May 28, 2013
Rated 5.0 out of 5.0 by Reflectix Does the Job Product was used to insulate the inside of my garage door. Cut the pieces to r the required size and taped only where required. Easy to handle and install. I was very satisfied with the results. February 18, 2015
Rated 5.0 out of 5.0 by Great Stuff Hi All. I find many uses for this Foil Insulation. Mostly in my Class A Motorhome. I line all the Cabinets facing outer Walls, to help insulate against the cold weather. Since I also do mostly all Boondocking, that's Camping off the Grid. As my Class A Motorhome is fully self contained. I also use this product in my Wet-Bay Compartment to help from Freezing Temps. I also line all of my outside Compartment Doors with it also. My 100 Gallon Fresh Water Tank, is right underneath the Bed, so I put so of this insulation under the Water Tank, which also keeps it from Freezing as well. And it also stop the cold from the Fresh Water Tank from passing up through the Mattress. It also protects all the Water Lines under the Bed also. August 26, 2014
