        I’ve seen fat kids that weigh considerably more. Keep in mind.

            Required a little bit of cutting for install but the fitment top to bottom was perfect. 10/10 would recommend to anyone that has a standard garage. Spring tension didn’t require adjustment on a single door but the double doors I had to put a full turn on each spring. The final look was beyond expectations. My wife approves so that’s a huge win.

              This insulation was the perfect addition to a Home Depot 9' x 7' Clopay garage door; saving a lot of money over buying a pre-insulated door. It takes some technique to get the panels installed, but is doable with a bit of patience.

              Very easy to put up and not a very big mess using the BOSCH T313AW3 3-Piece 6 In. Knife Edge Special for Soft Materials T-Shank Jig Saw Blades. I'm sure Home Depot has them and cutting cellofoam was a breeze and hardly any clean up. I read some reviews that said that they bend, I had no problem with that. It stayed straight and cut like butter. The panels went in with a little fussing but went in nice. Non of the panels broke apart when installing. A crumb here and there but nothing to complain about. When I got done it looked like I bought the garage door like that.

              Clean and good quality. Can’t wait to add the rest of the panels. You can tell the difference between the new and old ones.

              I installed 30 panels for my garage doors and used an oscillating tool to make the cuts. I first tried making the cuts with box cutter but it didn’t seem practical and switched to the oscillating tool. It’s winter right now and I noticed the garage is warmer by at least 10 degrees. Haven’t noticed any issue on weight being added to the door.

              Works as described!!! Huge difference!
              I installed these on my garage door as cold weather was In the forecast. After measuring each door opening they were easy to cut and they fit snugly into the garage door opening. You do not and I repeat. Do not need any adhesive. As long as you cut the pieces at least an eighth of an inch larger than the opening, then they fit snugly into their compartment. For two 9 ft by 8 ft wide doors it took about 2 hours but mostly that was measuring and cutting each time. But once you get the hang of it, it goes pretty quickly. As you will see in the pictures, it is currently 36° outside but inside the garage is 64° which is a huge difference. Normally it would have been the same temperature outside as it is inside before this insulation.

                Great Product.
                We added the insulation to our garage door today. It was easy to cut and install. The styrofoam can be a little messy to clean up. To early to tell if it’s going to make a difference.

                  Works and looks great
                  I used four packs of these panels an a roll of reflective bubble insulation on my two garage doors. I chose these panels over sticking just reflective bubble insulation because I did not want to deal with double-sided tape coming off over the years. My garage door panels were varying sizes so I took copious measurements, allowing 1/4 to slide under the supports. From scrap I cut a bunch of 2” wide blocks to slide inside the supports. Cutting the panels creates a styrofoam mess. Using a square and straightedge, I first made a shallow cut with a utility knife then a full cut with a longer sharp knife. I kept my shop vac handy and vacuumed often. Popping the panels in the door requires some finesse and working meticulously to not damage them but it worked well. All in all I have about R15 of insulation and the garage is much more temperate.

                    Just messy styrofoam...AVOID
                    Would honestly gives this a 0 if it let me Product is basically just Styrofoam. It falls apart and gets everywhere. Install isn't horrible but if you have to take it back out because it doesn't fit quite right it will break. Would not recommend this product.
