US Energy Products NASA Tech White Reflective Foam Core Garage Door Insulation Kit (9L x 7H) or (9L x 8H) Single Garage Doors R8 (Upgraded Tape)

first thing's first: follow the instructions for the adhesive "hold time." this product especially, but even 3M extreme duty double-sided tape, abound with negative reviews on the adhesive strength, despite proper cleaning and prep of surfaces.the written instructions indicate to leave the tape exposed to "tack up" the tape, and this is echoed by advice given for the proper usage of 3M tape. the included instructions say to leave the tape for, i think it was 15 minutes in warm temps, and up to 2hrs if temp is < 70F. the temp when i installed was exactly 70F, so i waited one hour, and so far (one month in), no falling panels.I also want to reiterate that the backside of the insulation should also be cleaned and prepped. my hands and its natural oils were all over the insulation while trimming to size, so it bears reiterating that these surfaces should also be cleaned and prepped just as well as the garage door surfaces themselves.anyway, the included utility blade was quite handy, and drives home the point to constantly be changing blades in any process with a utility knife. when sharp, the insulation cuts like that elusive experience when you're able to push through wrapping paper with sharp scissors.one install/fitting tip: many photos show the insulation being cut all the way around the V-shaped hinges at each garage door segment. this works... but of course leaves a bit of an uninsulated gap at the hinge. i found that it was easier and just as effective to simply cut two vertical slits in the insulation, flush with the interior vertical surfaces of the hinge, and then tuck the resulting flap behind the roller piece.(in the photo i've included, the top part is the panel i did second, where i figured out the "flap" technique, and the bottom panel is what i did first, and cut around the entire hinge.)in closing: no, this isn't going to look as polished as a true insulated door. but the quality of the insulating panels is polished enough to give a nice finished appearance. compared to other systems that use expanded polystyrene or other more DIY approaches with insulating boards, this is the better pick hands down for ease of install (e.g., not having to cut small foam panels to fit inside the door panel flanges), and also not having to worry about added weight for your garage door motor.anecdotally i'll report roughly a 5-degree swing from pre-and-post install during 30-40F degree nights where i am. i expect similar performance in the dog days of summer. even if the shift in energy spend balance is minimal, i know i would much rather have that extra 5-degree cushion than without.

The insulation kits arrived as promised. The installation was going great until I got to the last panel and I ran short of the double sided tape. I used some of the tape from the second kit to finish the first installation.I emailed U S Energy Products, Mike Davis, and he responded immediately saying he would ship another roll of tape out. I received the tape within 3 days and am now able to finish the second garage door. Great customer service!The insulation looks great and I am anxious to see how it helps keep my workshop warmer this winter.The installation took me a little longer because I decided to take the hardware off the doors and then reinstall it after the insulation was in place. This saved me from having to cut around the hardware and I think it gives a much better look to the overall appearance.Thank you Mike Davis for great customer support.

Works well. I definitely can tell the temperature is decreased in garage. Did run out of material so be sure to double check measurements. I was able to find a smaller amount to finish the garage door. Also, the tape doesn’t hold well so get some extra tape too.

I've a 3-car garage: 1 door for 2 cars, 1 door for a single car. I bought the 2-car pack first. This review is for the single-car door. 1 thing somewhat of a surprise was the texture of the white side is different from the 2-car door version, not as smooth but slightly thicker. It's also more expensive (more than half the price of the 2-car version). Installation was fairly easy. Remember to pre-measure each of the garage panels first and cut to size. The panels don't always have the same size. The included cutter is sharp enough for the job. Applying the (blue) double-sided tape took a little practicing. After fumbling on the first few panels trying to peel the blue protective side off, I ended cutting a small cross in the middle the tape after sticking the tape to the garage panel. That allows me to peel off the blue tape a little bit easier. After the installation, the garage came out to be about 5 degree cooler than the outside hot temperature around 95-100 degree (summer). I've a window AC in the garage which can cool it down to 10 degree below outside. I plan to add the garage vinyl sealer around the garage door edge. Hopefully that will keep it even cooler. Mike is very fast in customer service answering questions. Also even sent 1 extra role of blue tape.

The first set was ok. The knife that come with it does not last long at all. Use your own sharp knife. The second set I ordered was a different shade of white and does not match the first set I ordered unfortunately. Does keep my garage warmer .

Big shoutout to Mike-US Energy. I fell short on product due to 5 panel vs 4 panel order, I reached out to Mike and same day, shipped out additional insulation at no cost!!! Great customer service! The product is easy to install and cut my radiant temperature by 20+ degrees.

Not worth the time and effort it took to put it up. Product does not stick as described and I did everything according to directions. Constantly peeling off. I finally just decided that I was going to buy an insulated door. Save the money on this and buy a new door if you have to or something solid that’s not in a roll.

The insulation arrived in a very timely manner. Everything needed was included. The only problem was the tape. We vacuumed the dust and dirt off the doors, cleaned with krud kutter, then cleaned again with water. After the door was dry we applied the tape. We let the tape set up for the time period the instructions specified. During the time that the tape was setting up the temp inside the garage stayed above 70 and outside temps stayed above 50. A few weeks have gone by and the tape is already starting to peel off the doors. I would recommend spending a few more bucks and going with the foam panels.
