I Tested And Reviewed 10 Best Garage Door Insulation For Hot Climates (2023)

I recently purchased the Reach Barrier insulation kit for my garage door and I must say, I am impressed with its performance and ease of installation.

Initially, I considered other insulating products, such as fiberglass batts, but found them to be difficult to install and messy. The NASA Tech insulation seemed like a good option, but it required removing and reinstalling hurricane straps, which was a time-consuming task.

The Reach Barrier kit stood out to me because of its pre-cut panels. Each box covered a single car garage door, and I only needed two boxes for my 7' x 16' door. The panels were 24" x 48", providing enough material to create 16 panels per box.

Since my garage door had panels of different sizes, I had to trim the stock panels from the kit to fit each section. Initially, I did this alone, marking the dimensions and using a box cutter to trim the panels. However, I found it more efficient to have one person cutting and the other installing. This saved a lot of time and effort.

At first, I followed the instructions and used the stickies provided to secure the panels. However, I encountered some issues with the panels sticking to the stickies before I could properly position them under the hurricane straps. To overcome this, I cut the panels 1/4" longer in each dimension. This allowed them to fit snugly in place, and I only needed to use stickies on a few corners where there was sagging.

One of the advantages of the Reach Barrier product is that I was able to install the cut panels without removing the hurricane straps. The design of my garage door allowed me to slide the panels under the straps, and the straps actually helped hold the panels in place.

In terms of performance, I am impressed. My garage door faces west, and in the afternoon, it gets extremely hot, with temperatures exceeding 110 degrees. Before installing the insulation, the garage was uninhabitable, reaching temperatures of 102-103 degrees. However, with the Reach Barrier insulation, the ambient temperature inside the garage has dropped by 8-10 degrees during the hottest part of the day. While low 90s is still uncomfortable, it is a significant improvement.

To further enhance the cooling of my garage, I also installed a 10000 BTU portable room AC that ducts out the garage window. With the combination of the AC and the insulated garage door, the garage has become a usable space.

I recently installed this product on my south-facing garage door in Greensboro, GA and wanted to share my experience. The installation process took a couple of days, as we had to wait for the foam to adhere to the tape properly before using the door again. However, I am already seeing some promising results.

I had a FLIR thermal camera and decided to take some readings with the sun hitting the door. From the outside, the surface temperature was around 106 degrees, while the same panel from the inside registered at 81 degrees. The ambient temperature in the garage was also 81 degrees at the time. These initial results indicate that the insulation is working effectively.

The installation itself was fairly straightforward, following the manufacturer's instructions. It did require two people to complete the job. Since our door has different-sized panels, we had to do some trimming of the foam, but it wasn't too challenging. The third picture provided shows the work halfway done, and the final picture shows the completed installation. Overall, I found the design of this product to be clever in solving a common problem.

The material used for insulation is thin and lightweight, making it easy to cut with the knife provided in the kit. The two-sided tape included also seems to hold the insulation securely to the garage door. However, only time will tell how well it holds up in the long run.

In terms of time, it took me approximately four hours to insulate my two-car garage door. I did run out of tape towards the end, but luckily there was just enough to complete the project. There were also a few small pieces of insulation left unused.

I have a few tips for anyone considering this product. Firstly, make sure to measure twice and cut one panel at a time. Test-fit each panel before applying the adhesive tape, as even seemingly identical door panels may have slight variations in size. The flat plastic blade tool provided in the kit is useful for pushing the adhesive tape onto the foil side of the insulation and securing the panels to the door. Working from the center to the edges will help straighten the tape. Additionally, I found a carpenter's framing square helpful for making the numerous cuts required to size all the panels.

Since my garage door receives direct sun from dawn until mid-afternoon, the insulation has made a noticeable difference in the interior temperature. The quick shipping and competitive price of this product were also impressive. The seller provided excellent support, offering 24/7 assistance and even included their cell phone number in the instructions.

I was highly impressed with the ease of installation for this product. The instructions were clear and concise, making the process a breeze. While some slight trimming may be necessary for a perfect fit, it was not as time-consuming as I had anticipated. The pre-cut pieces made cutting to fit my individual 16-foot garage door a simple task.

The insulation itself was very easy to work with. The adhesive strips set overnight, ensuring a secure bond, and the individual squares of insulation were quick and easy to install. I immediately noticed a difference in both sound and temperature within my garage. This product has truly been a positive upgrade for my space, and I couldn't be happier with the results.

Although I did find the tape a bit challenging to work with initially, I soon realized that with patience and following the instructions to wait for it to get tacky, it worked well. Living in Nevada, where the heat can be quite extreme, I noticed a significant improvement in temperature control, especially when paired with my solar garage fan. I am absolutely in love with this product and its ability to keep my garage cooler.

I must also mention the fast delivery of my order. The product arrived promptly, allowing me to get started on the installation right away. The ability to easily cut the insulation to the perfect size was another added bonus.

I recently installed attic stairs and was not satisfied with the plain wood and visible screws on the exposed part. Additionally, I needed to insulate the entire thing. Thankfully, I came across a roll of material that exceeded my expectations.

The material I found is perfect for my needs. It features a shiny foil side and a white side, which blends seamlessly with the textured ceiling. I decided to double up on the material by cutting two pieces large enough for the panel and using adhesive to attach them. This created extra thickness, allowing me to align them perfectly with my trim. To secure the material, I used adhesive and glue, and then used clear tape on the edges while it dried. I also made a hole to accommodate a pull cord, and it looks fantastic. Not only is this material easy to work with, but it has completely eliminated any drafts.

The delivery of the material was very fast. However, it's worth noting that the three pieces of 2'x16' material came in one roll, which may be confusing if you were expecting three separate rolls. Luckily, a note with a phone number was included in case there were any issues, although I didn't encounter any problems myself. The material itself is of high quality, with strong foam and one side metallized with aluminum foil, while the other side has a smooth shade of white. It can be easily cut with a knife or scissors. Some sections of my garage door held the material well without adhesive, but for others, I used a bit of 3M 80 or 90 spray, specifically designed for foam. Overall, I had a great experience with this product, and it was definitely worth the money.

When researching garage insulation products, I found that this particular material worked best for my situation. Living in Arizona, my garage door starts to heat up around 3pm, which is the hottest part of the day. By keeping the heat out of my attached garage, not only am I able to lower my AC costs for the rest of the house, but I can also use the garage more comfortably in the early morning. Initially, I purchased thicker foam board insulation, but it didn't fit in the channels on my garage door and was too heavy. That's when I turned to this product, as its value lies in its ability to reflect radiant heat, which is exactly what I needed for the 3pm-sunset period. The material is easy to cut and install, and the white side even enhances the appearance of the inside of my door compared to what was there before. While I haven't experienced a full summer with this insulation yet, it appears to be helping during the hot weather we've already had. If you have a garage door that receives intense sunlight for most of the day, it may be worth considering a higher R-value option. However, for me, this product is working well and is much more affordable compared to other alternatives.

I recently purchased and installed this product for my detached garage, and I must say that I am extremely pleased with the results. My garage serves as an office and man cave, measuring approximately 30'x20' with two windows facing north and south. Despite having insulation in the attic and walls, the garage door, which faces east and receives direct sunlight from 9 am to 2 pm, used to radiate a significant amount of heat into the space.

Before installing this product, I could feel the radiant heat coming from the garage door, and my infrared thermometer showed that the temperature on the outside of the door reached 110 degrees Fahrenheit on a 91-degree day in mid-June. The concrete below the door was also extremely hot at 108 degrees Fahrenheit. However, after installing this product and measuring the temperature again, I was amazed to find that the inside of the door was only 105 degrees, while the insulation behind it registered a much cooler 83 degrees – a difference of 22 degrees.

The impact on the overall temperature inside the garage was noticeable as well. Prior to installation, I would set my thermostat to 76 degrees, and my AC would run continuously to maintain that temperature. However, after installing this product, the temperature inside the garage dropped to 73 degrees with the thermostat set at 76 – even on consecutive days with the same outdoor temperature. I have since adjusted the thermostat to 80 degrees, and it now effectively keeps the temperature at a comfortable 76 degrees. Additionally, the AC fan now consistently runs at a lower speed, resulting in quieter operation.

The installation process itself was relatively straightforward. I thoroughly cleaned the garage door using water and a degreaser, and then allowed it to dry overnight. The removal and reinstallation of the hurricane braces was a bit challenging, but manageable with one person. I used the self-tapping screws provided to secure the product back in place as close to the original position as possible. The tape was applied on the second day and left to dry overnight. In hindsight, I would have used two strips of tape for the vertical pillars instead of one, but even with the current setup, it feels sturdy and secure.

I would also like to mention the exceptional customer service provided by Mike, the seller of this product. He was responsive and helpful throughout the entire process. Despite a mishap with the post office losing my initial package, Mike promptly sent a replacement with expedited shipping once the issue was resolved. I plan on purchasing this product for my attached garage door, as well as for my water heater and other areas where I believe it could be beneficial.

I recently completed the installation of this product in my garage and I am pleased with the results. As a female, I was able to install it by myself, despite the high temperatures in the garage. The entire process took me around 5 hours, with the most time-consuming part being the removal and reinstallation of the hurricane bars. Having a second set of hands would have made this step easier and saved me time.

The insulation has made a noticeable difference in the temperature of my garage. Even in the extreme heat outside, my garage remains significantly cooler. I am impressed with this product's ability to keep the heat out and provide insulation. It has proven to be a worthwhile investment for my home.

I must also mention the excellent customer service I received from the seller. I reached out to clarify some installation details, and they were very helpful and responsive. This added to my overall positive experience with this product.

It has only been a week since the installation, so I cannot provide long-term durability and temperature readings. However, I will update my review in the future, especially during the hottest days of summer in Arizona. I am confident that this insulation will continue to perform well.

I recently purchased and installed this insulation for my garage door, and I must say I am quite impressed with the results. Even though I had no prior experience installing insulation, I was able to complete the installation over the course of two days, with a total install time of about 3-4 hours.

The package came with 4 individual rolls and a large roll of double-sided tape. The instructions provided two options for installation – either directly on the garage door panels or taped to the framework. I chose the latter option.

To begin, I thoroughly cleaned the surfaces I was going to tape using automobile window cleaner and a microfiber cloth. I then proceeded to tape all the horizontal and vertical surfaces of the panels. Next, I peeled off the double-sided tape paper from the top of each panel and rolled out the insulation on it. When encountering a joint, I used a razor blade to make vertical slits on each side and continued rolling and mating the insulation with the exposed tape. Once I reached the end of the roll, I cut off the excess and ensured all surfaces were touching.

Next, I lifted the garage door to my height and began peeling off the vertical tape strips followed by the bottom horizontal strips. After removing all the strips for each panel, I pressed the exposed double-sided tape onto the panels and checked for any missed spots. Finally, I trimmed off any excess on the bottom and moved on to the next panel.

I live in a smaller home with a south-facing garage, and our master bedroom is located above the garage. The garage used to get extremely hot in the summer and cold in the winter. While I was hoping this insulation would help with our utility bills and keep our bedroom cooler, I haven't noticed a significant difference in the overall insulation of our house. However, I am still extremely happy with the product.

Before installing this insulation, our garage would feel as hot or even hotter than outside due to the sun beating down on the door all day. But now, it is much more comfortable. I have noticed a significant improvement in the temperature during both summer and winter. Although I haven't measured the exact temperature difference, I would estimate it to be around 10-15 degrees warmer in the winter and cooler in the summer.

Additionally, my wife's car is kept in the garage, and she has noticed a considerable improvement in the comfort level when getting into the car to leave. Overall, if you spend a lot of time in your garage, I would highly recommend this insulation. I compared it to foam inserts at Home Depot, and not only was this product more affordable, but it also had a higher R-value and didn't require any door spring adjustments.

I recently purchased both the single-car garage door insulation kit and the double-car garage door insulation kit. Initially, I encountered a small issue as I have Wayne Dalton doors which required custom-cut rolls due to the ridge near the bottom of each horizontal panel. However, I contacted the owner, Mike Davis, and he quickly arranged for the return and order of the custom-cut rolls. I also had a couple of other questions which were promptly answered. The customer service provided by Mike and his organization was commendable.

For Wayne Dalton doors, I would recommend using not only the provided tape but also a staple gun and industrial-strength glue for extra adhesion. This is necessary to ensure that the insulation stays in place despite the ridge on the doors. The installation process took a few hours, hence the four out of five stars for ease of installation. However, overall, I am highly satisfied with the products and the service provided.

During the installation, it took me a total of four hours to complete the task. Most of the time was spent taking down and putting back the hurricane brackets. The installation of the insulation panels themselves was quick and easy, thanks to the clear instructions and plentiful double-sided tape provided. I immediately noticed a significant difference in the temperature within my garage. The most noticeable change was observed when standing next to the door. I am extremely pleased with this purchase from Amazon and the entire experience has exceeded my expectations.

As for single doors, the installation process is slightly different but not difficult. If you have Wayne Dalton doors, it is important to create a loop over where each panel connects to each other. This will prevent the insulation material from getting caught between the hinges. If you encounter any difficulties, the customer support team is available seven days a week and is incredibly helpful.

After installing the insulation, I noticed a substantial change in the temperature inside the garage, both during warm and cold weather. In fact, during a recent period of single-digit temperatures, my garage remained in the 40s, which is significantly warmer than usual. I highly recommend both the product and the company. In my opinion, they deserve an A+ rating.

I recently purchased the garage door insulation kit from Amazon and overall, I am quite satisfied with the product. Firstly, I want to mention that there was a slight confusion regarding the panel width. I initially believed that the panels were 21" wide, but they turned out to be 24" wide. However, the owner of the company personally called me to explain that they can custom cut the panels if needed. I was initially concerned about getting perfect cut edges like the factory-made panels, but I decided to make a jig using plywood and a utility knife to achieve a clean cut. With the help of my wife, it was easy to run the panels through the jig and achieve the desired results.

When it came to installation, I chose to remove all bracing and hinges in order to apply the panels and then replaced them afterwards. This process took a bit longer, but it resulted in a cleaner finished product. I followed the instructions provided and started with the top panel, then proceeded panel by panel to the bottom. I would recommend not removing the plates that hold the cables, as it can create a mess. Additionally, it's important to use the tape sparingly and to only use one piece on the vertical pieces in the middle. Thoroughly cleaning all locations where the tape will be applied is also crucial for best results.

As for the performance of the insulation, I will have to wait until summertime to see if it helps keep my garage cooler. Living in Florida with a garage door facing west, my garage frequently exceeds 100 degrees in the summer afternoons, so I'm hopeful that this insulation kit will make a difference. I also plan on using metal HVAC tape to seal off the end of the panels, as it is believed that the space between the door and the panels will help with insulation and radiant heat.

In terms of the size of the kit, there was a slight mix-up with my order. I initially ordered a 16' x 8' kit, but I received an 18' x 7' kit instead. However, this actually worked out better for me as I only needed to cut off an extra 2' along the 21" edge. I used a 12" metal ruler to make the necessary cuts.

The installation process took me about 4 hours in total. I found that following the provided instructions and using the included squeegee to press hard on the tape resulted in a good bond between the panels and the tape. I did encounter some difficulty when peeling off the tape backing from the end, but it was much easier around the door ribs. I also had spring cables running down to the bottom panel of my garage door. Instead of cutting out insulation to accommodate the cable brackets, I removed the top screw, placed the panel over it, and then put the screw back. I did the same for the bottom screw, ensuring a neat appearance.

In terms of the temperature reduction, I noticed a difference of about 8-10 degrees with the insulation installed. My garage temperature now tops at around 91-92 degrees, which is significantly lower than before. I am also considering using an external heat-shielding film to insulate the glass on my side garage door, as well as blowing cellulose insulation on top of the garage ceiling for further heat reduction.

I must commend Amazon Prime for the fast shipping, despite the current virus situation. Additionally, I reached out to the owner, Mike, via email, and he promptly replied, asking me to call him if I encountered any issues. However, I did not need to make the call as the installation went smoothly without any trouble.

I recently installed this garage door insulation and it has made a significant difference in the temperature of my garage. Before installing it, my garage would become unbearably hot in the afternoon and evening, with things even melting due to the radiant heat from the door. However, after installing the insulation, the garage is much cooler during these times.

The installation process was fairly straightforward. I carefully removed the hardware one section at a time and installed the insulation using double-sided tape. I then reinstalled the hardware over the insulation. The end result was very nice, and the insulation fits perfectly between the insulated panels, sealing the gaps effectively.

I did make a mistake during the installation by initially cutting a notch in the corner. I would advise against doing this, as it can potentially create an open space that defeats the purpose of the thermal barrier. Instead, it is better to cut slits and fold the cut piece into the hardware holding the panels together.

I used the insulation on a full-size door and it fit perfectly. The insulation has helped significantly in reducing the temperature inside the garage. I measured a decrease of 10 degrees Fahrenheit with the insulation compared to without it, even with the sun beating down on the door. This is impressive and I am satisfied with the product.

I also plan to insulate the rest of my garage before winter, as it has proven to be effective in keeping the temperature regulated. Additionally, I will be adding weather stripping to further improve insulation and prevent freezing in an add-on pantry area that does not have HVAC ducts.

The straight pieces of insulation that I purchased for my old garage door fit perfectly on each panel, with a little overhang horizontally. I easily trimmed it as needed around the hardware using a box cutter. It is important to keep the blade sharp throughout the cutting process. I used Gorilla Glue's mounting tape, which had excellent adhesion, though removing the non-stick backing took longer than expected.

I highly recommend using a cleaner or degreaser around the hardware and on the side edges of the door to remove dirt, oils, and exhaust build-up before installing the insulation. This ensures a better bond and effectiveness of the insulation.
