Yes, that's what the instructions said, so that's what I did. If you put the adhesive stickers on the raised portion inside the panels, it will automatically leave a space for air.

Answer: 
No, Its effectiveness is from the reflective surface and an air gap wouldn't help that. The insulating value of an air gap would be negligible, too.

It is obviously impossible to create a sealed air pocket on a garage door, so this product would not be effective.

Also avoid foam panels. Foam is very flammable and must be covered by an approved thermal barrier in a garage, home, basement, etc. The standard is 1/2" drywall -- so this cannot be used on a garage door either.
Home Depot sells another garage door insulation product that is based on standard fiberglass, and is easy to install: Owens Corning Model # GD01, Home Depot Internet # 202257272 Store SKU # 744925

Yes, the product is basically a mylar/foil covered bubble wrap of sorts with some rigid qualities that allow it to stay in place with tape. Although the tape is supposed to keep it pressed against the door itself, it has not been the strongest point of this product. The tape is somewhat problematic but, with some extra pieces of rigid foam insulation added to hold the barrier in the opening, the radiant barrier remained in place without problems. My door had zero insulation (aluminum pressed) and had enough space to handle the barrier and the foam core together. It works like a charm though... saves lots of HVAC costs in both the winter and summer months. For the price, you cannot beat this product. Read Less

Answer: 
Yes they cut easily with a pair of scissors. But cutting will create more pieces to put on the door, and you may run short on the stick-on tabs. Suggest you get a 20 ft double-sticky-sided Duck Tape and use it for the centers of the sheet instead of the little tab in the center of each sheet. My cutting and pasting worked out great with the double Duck Tape and included sticky tabs.

Answer: 
Sheila, yes they can be cut. There are several air "bubbles" per square inch, but cutting into them will not reduce the effectiveness much at all. The primary benefit of this product is its reflective properties of the two surfaces, not the insulating value. If you need or want more insulation, consider the styrofoam sheets (Garage Door Insulation Kit).

The third photo shows a temp of the lower right panel of 59.2deg F. this was the case where the radiant barrier was against the door and the insulation was facing the inside of the garage. So it made a difference having the radiant barrier on the inside. that's unfortunate because the insulation i bought from HD (unbradned) had a nice white plastic coating that made it look nice and easy to clean.

I'm installing this radiant barrier with insulation also. There is somewhat of a debate which side of the insulation to put the radiant barrier. the radiant barrier does best if there is an air gap between it and the radiant body (the garage door in this case). The problem with putting the radiant barrier on the door then putting the insulation on is that it eliminates any air gap between the radiant barrier and the door (or at least in my case with the thickness of the insulation). By putting the insulation on first then the radiant barrier you have created an "air" gap with thermal resistance using the insulation. From a system point of view you may have lost a little bit of effectivity by having the thermal resistance but you've also gained by having an air gap. As someone else said you don't chance the reflective properties of the radiant barrier in either case. you just change the performance of the system. All that said, I plan to install it door-insulation-radiant barrier but I'm going to do just the opposite on one panel so I can measure and compare it to the others in the winter and the summer to verify this theory Read Less

Bear in mind that the "Air Reflective" kit is primarily a "radiant barrier" and should be installed closest to the outside, with the Owens Corning insulating foam sheets installed closest to the interior of the garage.
This "radiant barrier" kit will nicely supplement the Owens Corning insulation kit. The Owens Corning kit will raise the R-value (insulating value) and the Air Reflective kit will lower the "e-value", which is to lower the emittance of radiated heat via reflection of the radiated heat. "Low-e" windows do the same thing.
Radiated heat comes from the sun and from objects outside your garage that are hotter than the garage door, such as the driveway, nearby bricks, cars in the driveway, etc. If your garage door faces north, then you're not getting any radiated heat directly from the sun, but will still get it from other objects.
This kit will be most effective at reflecting radiated heat from direct sunlight.

Rated 4.0 out of 5 by 126 reviewers.
Rated 5.0 out of 5.0 by Made a Difference I didn't really think they would make much of a difference but I'm pleased to say that they do. My garage/workshop gets the full South Carolina afternoon sun. It gets hot in there. Adding the insulation to the doors dropped the inside temp about 6 degrees on a similar day. Very easy to install. I made a cardboard template of one of the panels on the garage door and then just simply used the template to cut each of the 16 panels (2 kits) with a utility knife. Before doing that I wiped down each garage door panel and attached the included adhesive fasteners, 6 per panel, and let them set while I cut the insulation panels to size. Total installation time about 2 hours (including measuring twice). September 14, 2016
Rated 5.0 out of 5.0 by Stay cool with this Awesome purchase Easy installation, and it works like a charm. I live in Houston, TX. and the outside of my garage doors face the sun in the afternoon, all the way until evening; and these radiant barrier panels keep my garage cooler than ever before. Even in 100 degree temperature, you can tell the difference. I also added a portable A/C to drop my temps in the garage into the mid/high 70's. GREAT BUY! August 23, 2016
Rated 5.0 out of 5.0 by Really easy install, big difference This insulation kit was so easy to install with two people, it took about and hour to do a two car garage door. We used seven sticky tapes per panel and followed the directions regarding trimming and pre-installation cleanup. We have two garages, a single and a double, so I purchased three boxes. We will do the smaller garage today. It definitely makes a difference in the temperature of the garage and looks very industrial/space-like. July 12, 2016
Rated 4.0 out of 5.0 by Reflecting Heat I am located in the Phoenix area. My garage door gets direct afternoon sun and heats up to well over 100 degrees, e.g. 130+. I installed this product using double-sided carpet tape and attaching to the outside edges of each garage door section. I sealed the vertical seams using aluminum duct tape. Entire process took several hours to tape and fit all of the panels. After install my garage is still extremely hot but I believe that this is mostly because I have an un- insulated attic and the outside concrete transfers ground heat.. The reflective material does reduce the door temp by 20+ degrees and keeps heat from transferring through the door. September 6, 2016
Rated 5.0 out of 5.0 by Great Purchase The non-insulated garage door faces the west in Henderson, NV (southern suburb of Las Vegas) and the afternoon sun shined on the door for over 4 five hours a day. Before putting up the insulation kit, the door was too hot to touch and the garage temperature was unbearable. After putting up the kit, the improvement in heat transfer was incredible. Would highly recommend this product. Installed it on the panels of the door, however the instructions indicated that a better result would be achieved if it was installed on the frame, but I have absolutely no complaints related to how well the product is performing October 4, 2016
Rated 5.0 out of 5.0 by Good purchase This product was actually better than I hoped for - the instructions were simple and installation wasn't all that bad even using two kits to cover a 2 car size door - I cleaned the door surfaces and the surface of the insulation where the peel and stick pieces go and just to be safe also followed up with strips of the metal or foil type duct tape on some edges. The insulation has made an improvement with temps and noise coming thru. October 18, 2016
Rated 2.0 out of 5.0 by Installation is a pain - skip the liquid nails idea. I'm reserving my opinion with regard to how well these will insulate until it gets cold. What I really want to comment on is that putting it up was a pain. First, be aware that you will probable have to trim the panels to fit around things like hinges and door opener and handles. Not a big deal, they cut easily with a scissors. I even had to trim the panels down to fit my door. It is a standard size door, but the panels were too big. Again, not a big deal. Second, I read all of the reviews. Many said to forget the included foam squares, and use liquid nails. Sounded like good advice. WRONG!! What they should have said was use BOTH the double sided squares and liquid nails. The problem with the liquid nail idea is that it takes time to cure, there is not enough tack to keep the panels up while it dries. The panels kept falling off the door. That made a big mess - glue on the door and panels and no way to hold them up. We eventually had to try to position the squares in place but by then the liquid nails had smeared in all the wrong places. We finally got some double back tape up and that held the panels. My advice is to get some good indoor/outdoor double back tape and skip the liquid nails. It might add $15 to the project but it will save a headache and a lot of mess. I figure in a year when these things fall off the door, I'll have to scrape/sand the door, repaint and get another kit and double back tape and try again. That assumes it really does insulate. October 17, 2016
Rated 5.0 out of 5.0 by Simple and easy to install, and it works!!! This product is great and economical. I do recommend it! October 18, 2016
