I Tested And Reviewed 8 Best Sound And Heat Insulation For Cars (2023)

I recently purchased this insulation product and I have been extremely impressed with its performance. Living in San Antonio, Texas, where temperatures can reach 100 degrees Fahrenheit during the summer, I was struggling to keep my truck's cab cool even with the air conditioning on high. However, after installing this insulation, I noticed a significant improvement in heat reduction. I could touch the top of the cab on the inside and feel minimal heat, which was a remarkable change.

The installation process was straightforward, and I chose to use it under my headliner, giving it a unique aluminum foil look. It has been several months, and the insulation is still sticking perfectly. I even had enough to cover the back wall of the cab under the rear window and half of my hood, which adds to the cool aesthetic when I raise the hood. I do plan on getting a little more to finish the hood when the weather warms up. Additionally, I have also used this insulation in my Prius and Hyundai Senada, and it has significantly reduced rattling in the doors while providing a comfortable temperature inside the vehicles during both winter and summer.

Another impressive aspect of this insulation is its ability to deaden sound. I had an old jeep with transmission noise that was bothering me, but by adding layers of this insulation, the noise was dramatically reduced. The adhesive quality of the layers is excellent, ensuring they adhere to each other well.

Although this product worked perfectly for my application, I would like to note that it is a self-adhesive insulation blanket suitable for a variety of purposes. I used it to replace torn insulation material on the interior sidewalls of our furnace blower compartment, and it performed admirably. However, I would not recommend using it in high-temperature applications as the rubber insulation and adhesive may not be suitable for extreme conditions.

I recently purchased this product to use on the underside of my jeep, and I must say, it exceeded my expectations. The adhesive is incredibly sticky and the overall quality of the material is top-notch. I have yet to see any signs of deterioration, and I highly doubt that it will happen.

I also decided to install this on the underside of my wife's VW Taos to reduce engine noise. Although it didn't completely make the cab quiet, it did noticeably reduce the engine noise by a few decibels. It was definitely a worthwhile purchase. Next, I plan on using Butyl rubber on the door frames for further noise reduction.

The material itself is easy to work with and can be cut easily with a sharp utility blade. The paper backing is also easy to peel off, and I found that cutting through it made a cleaner cut on the metallic side. Installation was a breeze, especially with two people working together to keep everything aligned. The adhesive is excellent, and time will tell how well it holds up. We sealed all the seams between sheets with 3M high temperature aluminum ducting tape, and the appearance and fit were very satisfying. Overall, this is an excellent product with great sound deadening and heat reflecting characteristics.

Although I was hoping for a bit more sound deadening, I did notice a difference when using this product on the engine cover of my motorhome. It was easy to work with, and the glue has held up even after two weeks. The compartment is now slightly quieter.

I recently purchased a product that exceeded all my expectations. The item arrived promptly, and I was delighted to find that it was of excellent quality. It was also incredibly easy to work with and looked fantastic. However, the best part was the affordable price.

I purchased this product to deaden road noise in my hot rod, and it did the job perfectly. The installation process was a breeze, and the results were highly effective. The only downside I experienced was the cost in relation to the coverage area. I felt that I needed more of the product to cover a larger surface.

One aspect that impressed me was the incredible adhesion of the product. I had previously bought a similar item marketed for airplanes, which worked well but was extremely expensive. This product, on the other hand, was practically the same but at a fraction of the cost. I was thrilled to find such a high-quality alternative at a more reasonable price.

Additionally, this product was incredibly easy to shape to fit my needs. It adhered effortlessly to the surface I applied it to, ensuring a secure fit. If you have concerns about its adhesive properties, let me assure you that this stuff sticks amazingly well. In fact, I used it as a radiant barrier on the floorboard above the exhaust, and it significantly reduced the heat.

I recently used this product for sound deadening purposes in the wall between my kids' bathroom and my bedroom during a remodel. To my surprise, it worked exceptionally well in reducing noise transmission. While I cannot attest to its performance in vehicles, I can confidently say that it is highly effective for soundproofing walls.

The ease of use is another standout feature of this product. As long as you ensure that the sticky back does not touch itself, you will have no issues. The adhesive holds well and allows for slight adjustments if needed. Once pressed into place, it remains securely in position.

In terms of performance, I noticed a significant difference when driving on the freeway. While there were no scientific tests conducted, the absence of rattling and the presence of a solid thud when tapping on the fender liner indicated a successful reduction in rolling tire noise. It should be noted that this is a closed cell foam, not acoustic foam.

I plan on using this foam under the hood and in certain areas of the door panels, in conjunction with acoustic foam in the panels and speakers. However, I did add a layer of killmat as a base before applying this foam for optimal results.

A few suggestions for using this product: it is advisable to use scissors for cutting, and wearing gloves can help prevent the foam from tearing or snagging. It is important not to stretch the material or attempt to lift it once it has been pressed into place.

On a separate note, I also ordered this product for a restoration project, and it arrived exactly as described and without any issues. I appreciate that it comes in a roll, allowing me to cut precise sizes according to my needs. The product itself is of good quality, easy to use, and exhibits strong adhesion. Overall, I am pleased with its performance and highly recommend it.

While this foam may not be the highest quality available, it served its purpose well in sound dampening my doors. The adhesion is stronger than the foam's structure, so it is important to be cautious when handling it to avoid tearing. However, considering its affordable price, I cannot complain. Additionally, it was a pleasant surprise to receive a roll of reflective tape along with the product, which was an unexpected but appreciated bonus.

I recently purchased and installed these insulation tiles for my bare roof, and I must say, they worked perfectly. Before applying the tiles, I made sure to clean the roof surface with rubbing alcohol, and then it was just a matter of peel and press. The difference it made was remarkable – my roof now sounds like it's made of cement, and I can already tell that it will be much cooler in the summer.

One thing that really impressed me was the included metal tape. Not only did it provide an added benefit in terms of aesthetics, but it also helped ensure a perfect finish. I highly recommend getting the metal tape along with the insulation tiles.

In terms of installation, these tiles were very easy to cut to fit, and the adhesive was strong. However, I would advise being cautious and double-checking the positioning before making contact, as once the adhesive makes contact, it's not easy to reposition the tiles. Fortunately, I had plenty of tape included to secure the seams.

Although I haven't had a chance to drive with the insulation installed yet, I have high hopes that it will greatly improve the overall driving experience. I expect it to significantly reduce heat and sound in the cabin, especially since I used it to cover the roof of my vehicle. In fact, it has already made a noticeable difference in reducing the wind noise from the roof rack and overall noise in the cabin.

One of the things I appreciated about these insulation tiles was their good value. Not only do they seem to work well, but they also come at a reasonable price. I was able to cover both sides of the storage well in my 65 vehicle with just one pack of tiles.

In terms of application, it was a breeze. I used sharp scissors and razor blades to cut the tiles, and there was almost no waste. They fit perfectly to the desired size without any issues. I also found that they noticeably reduced sound and vibration in my doghouse and generator compartment in our Class A RV. The included tape was easy to apply and helped cover the seams and edges seamlessly.

I recently purchased this sound deadening foam for my window AC units and I must say, it's absolutely fantastic. The installation process was a breeze – I simply cut a rectangle to fit the window and made a space for the unit. The sticky back made it incredibly easy to insulate the side spaces, and I believe it also helped with reducing sound. The overall quality of the foam is excellent, and what's even better is that it has multiple uses. I highly recommend this foam for anyone in need of sound deadening material.

Another great use I found for this foam was sound deadening my car roof. I have a Prius, and after comparing it to my Camry Hybrid, I noticed that the Prius was not as quiet. Upon further inspection, I discovered that the lack of roof insulation and padding in the Prius was the reason for the noise. I decided to use this foam to sound deaden my car roof, and it worked wonders. I was able to unroll and apply it seamlessly, and with just one roll, I covered 2/3 of my roof. The foam, when used in conjunction with butyl sound deadening panels, significantly reduced the noise inside the cabin. My Prius is now just as quiet, if not quieter, than my Camry. If you're looking to sound deaden a large surface area, I highly recommend this foam.

For those who are in need of basic sound deadening material, look no further. I recently used this foam to sound deaden my 2001 2500HD, as the original insulation had been destroyed by rodents and time. I opted for a metal-backed material with a tar-like backing, and applied two layers to my complete firewall. The results were fantastic. I also used the foam to sound deaden the inside of all four doors, applying two layers of the same material. I also decided to line my under-dash cover panel, which houses my blower motor, with this foam. The application process was easy, and the foam formed well to the surface. Using a roller for adhesion helped greatly. For the price, I believe this foam is a good choice, but it's important to consider your specific needs. Personally, I prefer traditional metal sound deadening material for my doors and under the hood, but for other applications, this foam worked perfectly. I give it 5 stars.

I ordered four different sound deadening foams for comparison purposes, and out of all of them, the Nugevo foam stood out as the best. The Siless foam, with a thickness of 157mil, felt cheap and practically useless. The Ucell foam, at 394mil, was okay but overpriced and too light. The Doogo foam was simply not up to par. However, the Nugevo foam, with a thickness of 236mil and covering an area of 55 sq.ft., impressed me the most. The foil layer was thick and the foam itself was firm, and the adhesive was very good. I can assure you that you won't be disappointed with this foam. It's truly the best option out there.

I recently purchased and used this foam insulation for my GMC Terrain, both on the roof and the floor. The results have been impressive. Previously, on hot days with temperatures above 90 degrees, the heat would seep through the headliner and make the vehicle unbearably hot. However, after applying this foam insulation to the roof, I am happy to report that the roof no longer gets hot. In fact, it only gets slightly warm if the car is in direct sunlight. I usually park in the shade and remote start the car a few minutes before getting inside, and the vehicle is now cool and comfortable.

Additionally, I have noticed a significant reduction in road noise. It is now difficult to hear a fire truck until it is close by. The noise reduction on the floor areas is especially noticeable. The transmission and center console floor area no longer get hot, and I am hopeful that changing my tires to a brand name will eliminate all noise completely. The foam insulation was a generous size, providing more than enough to treat the headliner and floors. I even have some left over to apply to the firewall under the hood, which I plan to do soon. I will provide an update once I have driven with this additional application for a week or so.

Furthermore, I have an audio system in my car, and the sound quality has greatly improved since using this foam insulation. The reduction in road noise and sound from other cars' tires on the highway has made a noticeable difference. Overall, I am extremely satisfied with this product. I applied it over a layer of butyl mat, and the results have been fantastic. The noise reduction is impressive, and the product is easy to use.

The foam insulation comes in a large roll, and I found it helpful to unroll it and leave it in the sun for a short period to remove any creases. However, it is important to note that the butyl adhesive used in this product can jam up your scissors. I recommend having some WD-40 handy to clean your blades if this happens. The adhesive is strong, so it is crucial to ensure you have the exact shape and positioning you want before peeling off the backing paper. Once the foam insulation touches another surface, it is firmly stuck.

In addition to using this foam insulation for the roof and floor, I also used it to replace the insulation on the underside of my car's hood. The old insulation was falling apart, and finding the OEM part was challenging. I used the old insulation as a template and centered the new insulation on the hood. Working from the center out to the edges, I pressed the adhesive back evenly onto the hood. It is essential to thoroughly clean the underside before applying the insulation. To make the application process easier, I made a slice down the middle of the backing, allowing me to slowly peel it off while applying the insulation. The whole process was straightforward, and the foam insulation has effectively kept the heat from blistering the paint on my car's hood. Additionally, it has noticeably reduced the sound of the motor.

I recently purchased KilMat to insulate the makeshift cat houses my husband and I made for the stray cats in our neighborhood. With the arrival of winter in North Carolina, we wanted to provide them with some shelter from the cold temperatures, rain, and occasional snow. The insulation was easy to cut and had a strong adhesive, making it a breeze to work with. It seems to be doing its job well, as the cats have been snuggling up inside the houses with the warm sherpa blankets we provided. We also used KilMat to insulate the door jam of our home, and it worked great in keeping the cold air out. Overall, I am very satisfied with this product.

I also used KilMat to reduce the noise in my vehicle. While it made a noticeable difference, there were areas where I needed additional soundproofing. KilMat's low profile allowed me to use this product effectively in those specific areas. I was impressed with how well it adhered to the slick surface of my car. Just make sure to clean the surface thoroughly before application. I highly recommend this product for anyone looking to reduce noise in their vehicle.

In addition to my vehicle, I used KilMat to insulate the base of our bed platform in our motorhome. It serves the dual purpose of absorbing noise while driving and providing thermal insulation while sleeping. The lightweight nature of KilMat was a bonus, as weight is a concern in an RV. I still have plenty of product left to use in other areas of the motorhome, which is great. Overall, I am pleased with the performance of KilMat in my motorhome.

Another application where KilMat proved useful was under the metal sink. It effectively reduced the noise caused by water hitting the thin metal. This was a simple yet effective solution to a common problem. I appreciate the versatility of KilMat and its ability to solve various noise-related issues.

Lastly, I utilized KilMat to create a barrier on light poles to prevent the firefly lights from clanging against them in the wind. While this application was more functional than aesthetically pleasing, it served its purpose well. I had to secure the KilMat with straps when the temperature dropped below 50 degrees, but I am not concerned about its durability.
