Rated 4.5 out of 5 by 305 reviewers.
Rated 5.0 out of 5.0 by Very Happy The kit took about 1 1/2 hours to install (including clean up) on a double wide garage door. I cut the panels with a very sharp long blade knife which helped minimize the mess of small foam beads you'd get if you sawed or scored and broke the panels. Still, it took a while to clean up the foam beads as they tend to go everywhere. Temperature improvement in the garage is very noticeable. Placing my hand on the uninsulated portion of the metal door on a hot day was nearly painful to the touch, while touching the insulated portion barely felt warm. The garage door looks much better from the inside now as it has a clean, finished look. As other reviewers have noted, I plan to cover the seams where panels had to be butted together, but not in a hurry as it's not really that noticeable. October 31, 2014
Rated 5.0 out of 5.0 by Simple to install and looks great!!! This kit couldn't be any simpler to install. It's once of the reasons I got it. Also I like the nice looking white outside surface which you can wipe down with a damp cloth to clean when you need to. The width should be just fine for most doors, it's the length you'll need to trim down. I have a 2 car door and so I needed 2 of these kits. Measuring my doors the left and right sides of my door were 45-1/4" in length, while the 2 inner rows were only 43-3/4" in length. Check your own doors. Double Check, even triple check if you have to and then write the numbers down. I would suggest you do the work outside. I cut my panels in the back yard and then brought them to the garage. The Styrofoam makes a big mess!!! I cut mine from a table so I could stand up and do it easier. I measured length, use the razer blade to make a mark for length. I then used a Square that was large enough to go all the way across, made sure it was squared and then held down good and cut along the length, Shadow the first time and then all the way down on the next pass. (You could measure on each side and use a straight edge also for the same results and then cut along that!) A square is just a little quicker. The Instructions then say to snap off the end piece. To me that seems like it would break off chunks from the back side so I didn't do that. I got just a razer blade and use a small pair of vice grips to grab just the end, this allows me to cut much deeper then when it's in the tool. I could then just go along the part that's half way cut threw and cut it the rest of the way threw. When done, pick up and smack it a bit to knock off some of the form that's all over both sides. It gets everywhere, including on you!!! It was easy enough to then bend using the slits on the back side and squeeze it into a panel. I didn't have to bend to much. Mine all being a nice snug fit. Make sure you measure and cut correctly. You don't want to screw up a panel. I cut one at a time, installed and then cut another. Between putting up drywall in my Garage that didn't have it but in a couple small places and a bunch of lights to brightens the place up. These white panels just brighten up the garbage just a bit more, add a bit of sound dampening from outside noises, or noises in the garbage to the outside. Temp wise?!?! I just finished installing them about a hour ago and it's only 59 degree's out right now. Besides I don't have insulation on the ceiling right now. That's planned in the future. I did add insulation in the walls before I put up the drywall and installed a new double pane windows that I also got from Home Depot. It was the one Windows in my house that wasn't replaced when I got the house a couple years ago. The other good thing besides simple to install and looks great is that it doesn't add a lot of weight to your door. That can be a issue with the underrated springs now being over worked along with the garage door opener. This is just Styrofoam with a vinyl white cover on top. I've seen other kits that look like a pain in the butt to install. Or getting just a big sheet of foam insulation and cutting yourself, that stuff is heaver, takes a lot more work to cut it and had writing all over it that makes it look ugly. When I was done installing all the panels I got out the shop vac and vacuumed all the panels for all the foam that was all over the outside pf them and whatever was on the ground. That was the final step for me. The price is reasonable. Time is money and I didn't have to waste a bunch of my time. It shouldn't take you more then 1 hour per Kit and that's going pretty SLOW!!

Rated 4.0 out of 5.0 by Works Easy to install but still must be careful not to snap it. Does work. Sun on the garage door in the AM 146 degrees uninsulated 104 insulated. The first order was good. Backing was glued well and did not peel. Ordered 2 more. One order the backing was not glued properly and showed "bubbles " out of the box. After installing the backing peeled more. A slight inconvenience as I can spray glue the backing back on but poor quality control. On some sheets the backing was not square on the styrofoam - short on one end and overlapped on the other - again poor QC. One piece did fall off when the door opened but maybe I did not properly tuck it in the door. Have not fallen off since. Am happy with this as mentioned, it does work. July 5, 2014
Rated 5.0 out of 5.0 by Easy Install, works well Very easy install into garage door. Just make sure you have a long razor blade and a square to help cut a straight line. The only tip I would give it to measure the top and the bottom of each section just to make sure there is not a little difference, this can save you having to trim the panels. Also really like the hard backing plastic or thin vinyl that is used, easy to clean and looks really nice. February 28, 2014
Rated 5.0 out of 5.0 by Easy to install and does help the garage temperature Arrived in a timely fashion and was delivered to my door. The insulation is Styrofoam with some sort of stiffer coating on one side. I still had to cut the pieces to fit my garage door panels. There are grooves on the backside that will allow it to bend 'a little' so you can have a tighter fit. It definitely helped the overall temperature of the garage (outside 39, inside 54), and the ceiling of my garage is not even insulated. It also looks aesthetically better overall. I did have to tape about 3 of 16 panels (I have a double garage but one larger door so ordered 2 sets). It was NOT due to the product that I needed to tape, but my own error in cutting a piece to slide into an existing metal side panel. I just used white duct tape so it matched and looked great). Female age 55 needed no help, didn't even read the instructions although there is a video online I found for anyone that needs it. I did also measure each piece just in case the panels on the garage were somehow different. One side of my garage (4 panels) had metal bars on each side of the panel, so I cut a skinnier piece to go behind one metal bar and then the normal larger piece to slide behind the other bar of the door panel (so 4 panels in my door literally had 2 pieces of Styrofoam due to the way the garage door was made). Then I just taped the seam so it wasn't seen with white duct tape. The rest of my panels slid behind a metal bar on one side and tucked into groves on top and bottom. ONLY complaint is Styrofoam is just messy LOL, I swept and vacuumed those white pill balls from cutting the panels nearly 3 days lol. But that is to be expected with Styrofoam. January 27, 2015
