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

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.

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!.

Fairly easy to install after cutting to correct size. I'm in S. TX and even though the garage door faces East, it becomes unbearably hot by noon. This product makes a big difference and lowers the temperature by at least 10 deg. I wish they would include more of the adhesive pads, otherwise it would get 5 stars.

Easy light weight heat/cold barrier for Clopay metal garage door in Florida. I bought two boxes to cover my two car garage door. I was concerned about the heat and cold that is in the garage in summer and in winter here in Fort Myers Florida. I was very concerned about stressing my garage door opener with added weight on the door. These panels are light weight and do the job. I can tell you that I get really sweaty in the summer and my fingers get stiff from cold in the winter when I work in my garage shop. The Reach Barrier kit arrived within a few days. I used one morning to measure and cut all panels (21' x 24'). I placed the panels in each section of my two car garage door. I was easy to fold and slide each panel into place. That took about two hours for me, a guy who is 81 years young! Next day the easy part of peeling sticky squares (one of my FAVORITE tasks LOL), to place the squares on the door, then press the panel onto each sticky. I put two at the top of a panel at each side and pressed. Then one sticky at the bottom middle of each panel. You can see how each panel had cross members on the garage door. The insulation was tough and could be maneuverd to do the sticky squares with no problems. Rubbing alcohol was easy to prep for sticky placement. Please bear with me and stick it out on this review. You will be happy if your garage faces East or West. I measured the temperatures 12 hours after final installation. I took readings from inside and outside of my home. I am attaching photos. #1 = outside temp is 42.6 F at 1:30 AM. #2 = my home inside thermostat is 74 degrees F. #3 = inside my home in a room closest to the garage is 72.4 F. I placed a sensor in the middle garage that read 66.0 F. I can walk barefoot in the garage at 1:30 AM! I placed a hand one the door in the afternoon sun and felt heat...then placed my hand on the installed barrier...there was a NOTICABLE temperature difference. I highly recommend this company and product. I wish that I had installed the panels four years ago when I bought this home! I plan on adding a follow-up temperature comparison this coming summer, when garage tempertures are easily 20 degrees higher that outside afternoon sun!

I’ve been wanting to insulate my garage door for some time, but didn’t want to add so much weight as to require adjustment of the springs. Also, I have hurricane braces which I needed to work around. The Reach Barrier was the perfect solution for me. My garage door gets direct sun until noon and adding the insulation has made the garage interior much more tolerable. Double garage, so I ordered two kits. Cutting the panels to size was a breeze; I just used a sharp pair of scissors. My outer panels are all 48”x21”, so I measured and cut one and used it as a pattern to cut 7 more. The inner panels were 43”x21”, so I measured and cut one to include tabs at each end to cover the area behind the vertical frames, and again used it as a pattern for 7 more. (The second photo shows the area my tabs covered). I used the included sticky squares, 6 per panel. I peeled up just a corner of the cover of each square right before putting the insulation in place. I then lifted the insulation just enough to pull the cover fully off each square in turn. The minor creases in the insulation are because the pieces arrive rolled up in the box, but the bubble layer sandwiched between the foils is not compromised.

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.

Easy enough to install. Doesn’t weigh down door too much. I thought it made a difference but not really. It does stop some of the heat, when sun hits garage door it heats up only the exposed metal, the insulation does stop the high heat but insulation does get warm. Garage still heats up to 82-86° with insulation installed. Laser temp gun shows walls and ceiling cooler than garage insulation. It was worth a try but I don’t see much results.

Easy install. Box is enough for 1 garage (single) door. Not enough stickers and based on reviews, I purchased more from the hardware store. Measured and used scissors to cut which was easy. Looks great. Quality seems good also, thickness, not too heavy. I’m in NE Florida. The insulation has made a huge improvement!!!

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.

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

Facile d'installation! Très satisfait.
