Reach Barrier Garage Door Insulation Kit, Reflective, 8x8 Single Door

I looked at the published R-values of this product and NASA Tech. They are both broadly listed as R-21. There are better insulating products available usually of the fiberglass batt type but these can be "dirty" and difficult products to install. The NASA Tech originally looked like the best bet but to install it, I would have had to remove the hurricane straps (5 of them), unroll the NASA Tech, marking the holes where the hurricane straps were bolted and reinstall the hurricane straps and bolts. Not a small job. I elected to purchase Reach Barrier becasue of the pre-cut panels. First, one box covers a single car garage door. For my project I needed two boxes for a 7'h X 16'w door. Second, each panel in the Reach Barrier Kit is 24" X 48". There's enough product to do 16, 24" X 24" panels per box Third, not every panel on my garage door (an Amarr Product) is the same size. The outside panels (closest to the roller tracks) are 25" wide, 21" high. The others are all 23"w X 21"h. Each panel had to be trimmed from the stock panels in the kit. I started the project by myself by marking the dimensions with a marker, labeled the L corner and top of each trimmed panel and would trim the stock panels to size using a long straight edge (a level) and box cutter. The panels trim neatly and easily with a box cutter. I switched to one person cutting (my wife) and the other (me) installing it - that saved a lot of getting up and down from one's knees. The first 4 or so panels cut and installed solo were slow going; it took about 10-15 minutes each panel to trim and install it. Going slow like this with one person doing the cutting and installing would take almost 3h to do one half of this project, 6h total. Too long. Get the wife, save my knees! Once we got a system going we did the other 28 panels in about 90 minutes. They advantage of the Reach Barrier product over the NASA tech is that I was able to install the cut panels without removing the hurricane straps. If you look closely at the photos of the completed garage door, you may note that the hurricane straps will actually hold some of the panels in place (there is enough space between the aluminum panels and the hurricane straps to easily work the cut panels under them). I started out using the stickies per the instructions. The problem with that was installing the stickies on the panel, removing the top covering of each of them then trying to slide a panel under a hurricane strap without the panel sticking to them until in place. After screwing up one panel that way I stopped putting the stickies on all four corners and in the middle. Instead I started cutting the panels 1/4 " longer in each dimension. Voi-la. They fit snuggly in place (mostly). If there was a saggy corner, I'd put a sticky under it by rolling the corner back, placing the sticky then unrolling the corner onto the sticky. That was only required on a couple of panels. The design of the door made it possible to jab that 1/4" extra of material in a grove and it stayed in that grove even with the door operating multiple times to test this technique. I imagine that wouldn't work on some door designs with or without Hurricane straps and you'd have to use the sticky is The important thing for DIY'ers is that you can easily install this product successfully even when leaving horizontal hurricane straps on the door. As for performance, I'm impressed so far. My garage door faces west and in the afternoon the door gets blazing hot - likely over 110 degrees. The garage is uninhabitable in the heat of the day with inside garage temps reaching 102 - 103 and it is presently serving as a storage area for heat sensitive things. I'd estimate that the insulation alone drops the ambient temperature inside the garage 8-10 degrees in the heat of the day with full sun on the door. Low 90s is still uncomfortable. My garage is about 450 SqFt. I just installed a 10000 BTU portable room AC that ducts (intake and exhaust) out the garage window. With it set at 80 degrees, it has no problem getting the ambient temp down to just under 80 degrees - comfortable for us. In the heat of the FL sun, the combo of a portable AC and the garage door insulated with the Reach Barrier product makes the garage a useable space. All I need now is a solar shade for the 48" X 48" window that I noted today leaks a lot of radiant heat now that the garage door isn't doing that!.

3 year update: I never would have guessed, but I've absolutely appreciated what a HUGE difference these insulation panels make in maintaining the temperature in my garage during freezing winter temps as well as 100+ degree summer temps. They consistently keep the garage temps 20 degrees closer to a comfortable 70 degrees than the outside temps, no matter which way the thermometer is reading. I've gotten to where I recommend them yearly to the ppl in my community every time we have an uncomfortable swing in temperature, and some even bother to come back and say "thanks!" ====== After having to use my garbage cans, plexiglass, carboard, and an old sleeping bag to basically tent the wall adjacent to the main water line coming into the house, then a space heater blasting on that drywall to try keep the line thawed during Winter Storm Uri last year, I decided this year that this was happening! Living in the Deep South, DIY garage door insulation kits have been hard to find at big box stores, which is why I haven't done this before. This year I was doing my Black Friday shopping online and this kit came up my search. I compared it to several others, read the reviews, decided that for the sale price, it was absolutely worth a shot. I also bought some heavy duty double-sided tape I like after reading about others' disappointments with the velcro attachments that come with the kit. The installation of this was super simple. I read the instructions, then decided to install it a bit differently because I wanted to maximize the air gap between the garage door and these insulating panels. These panels are about 2" too tall and 1" too wide for my garage door panels, so I folded the excess down, creating a U-shape on the top for extra support for the gap, and an L-shape on the side so I could secure this insulation to the interior side of metal brackets that hold the garage door together. I ended up only using 2 small squares of double sided tape per panel to attach it on opposing diagonals. Now that I know it works well, I'll be going back and securing it in more places to make the garage door look better. It took me about 2 hours because I kept experimenting with the installation to get as much air gap as possible while keeping the insulation securely in place. I'm super pleased with this product, and considering getting some more to insulate the attic ceiling this summer. Today was the first day to really test how these perform. It in the low 30s today when I took this picture of my car's thermometer.

For these panels being light weight, they do pack a heavy punch and perform as described. Some of the panels did require a little trimming, which was easy to do. I did notice a huge difference in the temperature in my garage and in the room above the garage and that street noise is more muffled. It is definitely cooler during these cruel hot summer days. I have no reason to believe that these panels won’t hold up during colder weather. The reflection is not blinding from the lights and gives the garage a new look. However, the only reason that I gave it a 4 star rating, is because of the double sided sticky pads. Some didn’t hold well or stick at all. I still highly recommend these.

This is not enough to fit a two car single garage door but the panels that came with (I would need four more) helped keep the garage significantly cooler this year over the last two years - it’s still warm but I can atleast go in and not break a soaking sweat - recommend this plus the privacy film for windows too!!

Didn't have to cut, just folded edges to fit and used the included sticky squares. I'm in SC where it's been over 100 degrees almost every day and the panels are still in place, sticky squares still holding. While it was fairly easy to install, I don't recommend doing it with your husband, it's like hanging wallpaper together, just don't do it LOL I also purchased a window a/c unit, but after installing this insulation, it doesn't have to work as hard and the garage stays cool. My door has 16 "rectangles/sections", so I ordered 2 boxes, which was just enough. Also reduced the noise level of the door going up/down.

The panels did not stick to the garage door. 3 had to be reinforced with double-sided tape and there were not enough sticky tabs included. Have not noticed a difference in the level of heat.

Great easy project to help your garage. Stay cooler in the summer and warmer in the winter. Joe was amazing and I highly recommend using this product.

2 degrees difference between applying this product and bare garage door. I spent 90 minutes cutting the product to size and installing it according to instructions. I was happy with the application but totally disappointed in practicality. My garage doors don’t get direct sunlight but it over 100 degrees inside my three car garage in the summer time in Southern California. I have a double garage door side and a single garage door side. I decided to do the small garage door first so I could compare it against the uninsulated side. Installation was straightforward and easy. After completing the install I took my infrared thermometer and hit the uninsulated double garage door. It showed 107.5. I then hit the insulated single garage door and it read 105.3. Two degrees!! Totally not worth the effort and money. No discernible difference. Save your money on this product.

Why sell a garage door insullation kit for only part of an average garage door? Does not make sense. Deceptive.

Worked perfectly and easy to cut and install. Was worried about adding too much weight to the garage door with other types of insulation and this lighter version of insulation did the trick

Very easy installation. Gives it a clean finish. One thing I will say is I suggest getting more of the stickems or using an adhesive spray when installing. The provided stickems did not do a good enough job keeping the insulation panels in place.
