Ant NASA TECH White Reflective Foam Core 2 Car Garage Door Insulation Kit 18 Ft (Wide) x 8 Ft (HIGH) R Value 8.0 Made in USA New and Improved Heavy Duty Double Sided Tape (Also FITS 18 X 7)

Great product and excellent customer service. It was easy to install, house temperature over garage greatly improved.Unfortunately the bottom row of insulation fell off 9 months later. I reached out to see if I could purchase another roll of tape to reattach the insulation and they offered to send a new roll free of charge! Highly recommend both the product and the company

The day prior to installing the USA product, I had to install a Styrofoam garage door kit from Menards (Midwest box store) as I couldn't get the garage even close to 70 degrees. I live in KS and installed the product when we had 30-40 F highs, and 15 F or so lows outside, and very windy. After installing the Menards product I used a small propane heater to get the garage close to to 70 F, but there was still quite a bit of air movement inside the garage. The garage is on the afternoon shaded side of the house, so we don't have an unbearably hot garage issue in the summer.After installation of the USA product, the same heater easily and quickly got the garage to 80+ F, with virtually no air movement inside the garage.One reviewer said they had to install insulation over their garage. I poked my head up in the attic access, and no insulation either. So I blew in insulation in the attic prior to installation of either product. I am kind of embarrassed I didn't think of that. Although attic insulation helped, the garage door was just too large of a heat sink to allow the garage to heat up.I have an 16 X 7 garage door with four 21" tall panels. I trimmed the sheets to 20 7/8" high and 16' 2" wide prior to installation. Note the ends of some of the rolls are not square, so be sure to check if you are pre-cutting the pieces. As I only had two hurricane bars, I decided to remove those and the hinges to get a much cleaner look. I did cut around the bottom roller as I didn't feel like unwinding and re-tensioning the torsion spring. Don't kill yourself with the bottom rollers!Overall, one fairly handy person can install this product easily. Use rope or wire to raise and hold the removed hurricane bars, it make re-installation very easy. I am a 60 yo pretty handy male.It was 20 F outside this morning, and the garage was about 55 F, so overall very happy. The product look great and durable. I have about 1/4 of the roll of sticky tape left (and I taped the vertical sections) and some insulation left too, but just pieces.I didn't have to contact Mark, but the reason I picked this product was due to the repeat and glowing reviews of his customer service. I recommend this product highly.

My wife and I installed this insulation yesterday on a 16 foot garage door. Nice clean appearance using the white side out. Job duration roughly 3 hours. The garage is definitely warmer; we have a radiant heater in the garage which now keeps up with cold weather. Installation tips: 1. tools needed: razor knife with 6 or more new razor blades 2. Large metal T square for accurate 90 degree cuts 3. 48 inch rigid metal "ruler" that can be used as the straight edge to guide cuts over 16 foot width...plus/minus depending on your door 4. knee pads: you will need these to be able to protect your knees and keep your focus on straight cuts. 5. two people to manage the fitting and adhesion process. 6. Sharpie pen to mark your cuts 7. provided squeegee. Suggest start by determining the height of the panels on your garage door...then cut a wooden stick to be used as your guide throughout the process. Begin with the lowest panel on the garage door...then as you get better at the process you will be working on the upper panels that are more easily seen...you want these to look great. Raise the door so that the lowest panel is at a nice working height. Unroll the panel with white or silve side up depending on your color choice. Look at the edges of the insulation...if it has an uneven "wave" due to the way it was cut...suggest take the 48 inch metal ruler and place it along the top or bottom border and "cut away" with razor knife any uneven cuts....you are looking for a straight line along the upper and lower surface....make it straight and your job will benefit. Now.... Mark the selected height using your guide stick about every 3.5 feet with a sharpie. Now place the 48 inch metal ruler along the sharpie marks and confirm you have a straight line....now hold the ruler in place with a hand and knee and using a NEW razor blad cut the height along the required length. When complete, you and partner "fit" the insulation into the panel and mark the desired length with a sharpie. Take the insulation down and using the t square cut the length as desired. Now you are ready to use the two sided tape. Using windex spray, wipe along the top and bottom of the garge door panel where you are going to apply two side tape. When clean and dry two of you work together...one unwinds the tape as needed and the other carefully aligns the tape along the top of the panel as you go across the panel width. Cut with razor knife. When tape is adhered...use the hard end of the provided squeegee to firmly press the tape against the door. At each end of door you may wish to place a vertical tape line to keep each end tight against the door and reduce gaps. Now repeat the process along the bottom edge of the panel Recheck your fit and position. When ready remove the tape protector along the top (do not expose bottom tape yet) to expose the adhesive along the entire panel length....Now two of you hold up the cut insulation...one holds the bulky insulation in the general position needed and the other carefully moves along the line and pushes the insulation tightly in place along the entire door...two of you move as a team across the door. Now expose the insulation on the vertical tapes at the end of the panels and the entire bottom length of tape across the door and press the insulation in place. Now take the provided squeegee and using the padded end push the insulation in place. Voila....one panel done. Now change the razor blade in your razor knife so that each panel has a fresh blade. Repeat this general process, don't rush...you will have a good looking door. Good Luck! Hope this helps each of you.

I had 5 horizontal rows for my garage, so I needed another row worth as the rolls would have fit a 4 row setup. The excess I had would have fit if I didn't mind a splice in the middle. Figured I would like the look to be a whole piece so needed to get another roll of the insulation and more tape. Called the number and the owner, kid you not, picked up right away and had the extra roll and tape sent out to me the next day, and I received it about two days later. Was able to finish the job and he would NOT take any extra money for it. Truly an amazing company and rare to see a company go far beyond what they should have to just to make a happy customer. The product was easy to install. Had a buddy help me and it went up in no time and does a great job keeping the AZ heat out of the garage. Would give 10 Stars for the company and product!!!
