Between physical damages to the components and the evaporation of the crucial fluids, there are many potentialconsequences of overheating your vehicleways to avoid the negative effects of heatmost of them can also help you soundproof your carfrom outside noise as well. With that in mind, today were talking about more than 10 of the best automotive sound deadening and heat insulation materials on the market.

Weve already discussed the causes of excess noise in a cars cabin in my article aboutreducing wind noise.Cracks, gaps, and other vulnerabilities in the construction of the vehicle are the most likely culpritsthere. Additionally, like sound, heat can also pass through those cracks. So if you want to deal with these problems, youll need to locate the root cause and use the appropriate insulation materials.

Before I tell you about the best products you can use for your car, I wanted to go over two things. First, well talk aboutthe types of insulation productsthat are out there; then we can go overthe general features youll want to be on the lookout for.So without further ado lets just dive in.

Which Sound and Heat Insulation Product Should You Use?

Things to Keep in Mind When Looking for Automotive Insulation

What Determines the Effectiveness of the Products?

The Best Car Sound Deadening and Heat Insulation Materials (2021)

Which Sound and Heat Insulation Product Should You Use?

Whenit comes to heat and sound insulation, the main principles are thesame. Basically, we want toeliminate any weaknessesthat may be letting sound or heat into the vehicle. The easiest vulnerabilities to spot are the actual chinks in the cars armor theplaces where the air is free to flow. Because heat and sound both travel by air, your first task will be to get rid of any places that might let air into the cabin.

However,heat and sound also pass through materials, especially since the sheet metal most vehicles are made of is an excellent conductor of both. In fact, the metal can even make random noises likerattling car doorsmuch more pronounced. Fortunately, there are plenty of materials you could use to make your vehicle more sturdy and less prone to rattling.

For example,rubber is an excellent option to use for both soundproofing and heat insulation, and so are some other materials Ill talk about. Basically, its all aboutadding a bit of bulk to the thin metal car parts. However, if you want to combat overheating, youll want to use materials that are heat-resistant as well. So lets review the types of materials you might come across.

If you have some experience shopping for automotive sound deadeners or heat insulation, youve probably seen foil mats before. Foil sound deadening mats have afoil front side and a black rubber or asphalt-based material on the backwhich is usually adhesive as well.

These materials are particularly effective, as they can helpabsorb excess engine noise and stop loose metal parts from rattling against the sheet metal. Those that are heat-resistant as well can also help youmanage the temperature of your vehicle.

Mats are somewhattricky to applysince you have to rub them into the sheet metal andavoid getting it stuck to your skin or your clothes. Still, once you stick it to theinside of your car doors, the headliner, the trunk, on the floor, or under the hood, youll be all set.

Most manufacturers make sound deadening mats inrolls or rectangular-cut packs. However, some of the products Ill tell you about also have kits for the hood, floor, or trunk.

Fiber and foam insulation products aretypically used underneath the floor mats or the carpeting. Theyre supposed tothicken up the floor of a car, which can have several effects when it comes to sound and heat control. Namely, fiber and foam can greatlyimprove the acoustic quality of the car cabin and make your conversations or the speakers sound better.

Now,most of these products arent waterproofby any stretch of the imagination, which is what bothers me about them. After all, our vehicles need to be able to withstand a decent amount of rainfall, not to mention whatever you track inside on the bottom of your shoes. Still, theres a time and a place for these kinds of products.

Liquid insulationis themost recent invention in the world of automotive sound deadening and thermal management. Basically, these kinds of products aredispersed using an air compressor-powered spray gun. A spray product allows for a more even application that isnt always possible when youre using other insulation products.

In my experience, liquid insulation alsolasts longer than adhesive or non-adhesive matstoo because they fuse to the metal in a more reliable way. However,the jury is still out on the effectiveness of spray insulation.

Even though most people still only use foil mats, sprays have been gaining in popularity. Still, most of the materials I chose to feature today are regular sound deadening mats. After all, theyre the most popular solutions by far.

After I go through 10 of the best sound and heat insulation brands on my list, I also wanted to talk about finishing tapes. These products arefairly similar to the foil and rubber matsI already mentioned. In fact, some companies make both types of products. However, finishing tapes are obviouslyonly for adding the final touches to your self-adhesive mat installation.

When you roll all of your mats into the sheet metal, you can use finishing tape to close the space between different pieces of mats. The tape is usuallythinner and therefore less effective than mats, so it wouldnt make sense to use it on the entire surface youre looking to insulate. Still, Ill link to a few great options after I tell you about the main types of insulation products, so you have the full scope of options laid out before you.

Before you buy the first product you run across, you ought to ask yourself a few questions. The most I can teach you is which brands you can trust. However, youre going to have to determine which products are the best for your vehicle. With that in mind, lets talk about some of the most important questions:

Answering these questions should help you figure out the pros and cons of the products Ill feature later on, so you can decide for yourself which of them is the best for you.

The effectiveness of insulating products most often boils down to their thickness. After all, most insulating products are made to handle either sound or heat or both of those things. So they should all work to an extent.

Still, some insulating materials are undoubtedly more effective than others. A key piece of evidence to support that is the fact thatmany people only use sound deadening matsand never give so much as a thought to the other options Ive mentioned. Sure, some of that has to do with the familiarity of the products. But is it possible that mats are simply more effective than sprays and non-adhesive fabric and foam products?

Well, thats not necessarily the case. As Ive already mentioned, most of the time youll want to keep your eye on the thickness of the product. Usually, that measurement is expressed inmils or thousandths of an inch.

The most effective mats on the market are 80 or even 60 mils thick. Still, there are also thicker and thinner versions of most of the products Ill tell you about. However,thicker mats are usually harder to install, so most people stick to the high mid-range of thicknesses of around 60 mils. Make sure to read user reviews for each specific product to check if its hard to cut.

Alternately, you can also use materials you dont need to cut, like sprays.An even coating of liquid insulation dispenses about 20 mils of product. Clearly, thats not enough to make a real difference in your car. Fortunately, you can pretty muchapply as many layers of the stuff as you need but Id cap it at 3, maybe 4.

In addition to the thickness of the products, there isone more thing that affects the performance of insulating products. Of course, Im talking about the base material theyre made of. As I have said,if youre worried about thermal resistance, your best choice would be to go for a rubber-based product.

More specifically, the best deadening mats usually havealuminum foil on the frontwhile theadhesive material on the back is made of a synthetic rubber material called butyl.

However, the adhesive layer of sound deadening mats can also be asphalt-based. If youre wondering whether you should get butyl or asphalt, I always recommend going for rubber. Basically, my preference is due to the heat-resistance of the materials.

Namely,butyl is certainly more heat-resistant than asphalt, as it can handle temperatures of up to 240 degrees Fahrenheit. Conversely,asphaltdoesnt tend to handle heat well at all. Itcan melt, leak, and even omit a particularly strong odorfor long stretches of time. Still, if you dont live in a hot climate, and if your car isnt prone to overheating, you should be able to use asphalt-based mats without worrying about the consequences.

When it comes tospray insulation, though, its a different story. These kinds of products can berubber-basedtoo. Still,ceramic liquid insulation is definitely more prevalent. Fortunately, both of these materials can withstand similar amounts of heat, so ceramic insulation should be able to give you some thermal protection as well.

When I was compiling my list of products to feature here, I wasnt really thinking about the order in which Id put them. However, now that I see the finished result, I cant imagine a different list.

Naturally, well begin by talking about the most popular and most effective products on the market. As we move toward the end of the list, Ill get into some more surprising and lesser-known brands. So without further ado, lets check out the first contender.

Noico is thenumber one brand in automotive insulation, at least as far as Im concerned. Admittedly, I may be a bit biased, but itscheaper than its main competitor, Dynamat, and about as effective. However, unlike Dynamat, Noico mats are amixture of both butyl and asphalt, which does come with minor inconveniences (readNoico vs. Dynamatfor more info).

Still, Noico mats are actually boththicker and more malleablethan the more expensive Dynamat products.Noicos 80 mil matis one of the most popular products in this category. It comes in9 squares that are 29.5 by 19.5 inches, making a total of36 square feetof material.

As youll see if you check out the products Amazon page,the sheets have the black adhesive material in the back, covered by a protective paper youll be able to simply peel away. Thesilver foil frontof the material is also notable, as itdoesnt have any brand markingson it, instead opting for anelevated pattern. When you go to install this material, youll be able to see exactly which parts youve applied enough pressure to by the depressions in the pattern.

This material ishighly heat-resistant and mostly odorless, after the initial smell that comes from unpacking and installing the product. The exact same product is also available withblack foilon the front. If the insulation is going to be visible, I recommend opting for the black foil rather than the silver.

Furthermore, 36 square foot version isnt the only one thats available. Noico also makes10and18 square footpacks for people who arent planning on insulating their whole vehicles.

While were on the subject of Noico products, Id be remiss if I didnt mention their Green Liner. The product consists of a layer ofclosed-cell polyethylene foam with a green adhesive rubber layer in the back. At 170 mils (or a sixth of an inch)thickness, this material is truly excellent for keeping out the heat and the cold as well.

The material is alsowaterproof (as well as oil and petrol-resistant)and fairly cheap as well. Noicos Green Liner is available in packs of18 square feetand36 square feet. You could even get it in9.5 square foot packs of340 mils(a third of an inch) thick material.

This combination of materials can easily withstand up to 212 degrees Fahrenheit, and theyre sure to lessen the amount of noise thats coming from your engine.

Dynamat has long been thereigning champion of the automotive insulation game. However, there are certainly valid reasons why it was so easily knocked off the first place position. Namely, it wasthe most expensive material on the market, and also one of the most difficult ones to install.

Still, if youre someone who wants to really invest into the sound and heat insulation of your vehicle and you can pay someone else to install it by all means, go for Dynamat.

Dynamat products are probably thepurest butyl insulation youll find. Most of them have the standardblack foil with Dynamats logoprinted over it in white or silver.

The Dynamat Xtreme pack consists ofnine 18 by 32-inch panels, which brings it to36 square feetin total. The67 mil versionof the mat is the thickest they have available. Yet even that should be enough to provide vibration damping, sound absorption, and heat-resistance to your vehicle.

Unlike Noico, Dynamat doesnt have a pattern on the foil to tell you when it has adhered to the metal. So you may have tobuff it in a bit more thoroughly just to be sure. Whats more, even though its not as thick as Noico, Dynamat is apparentlyharder to cut and bend into shape.

Still, this brand has given us a lot of firsts we should be grateful for, and they keep innovating. For example, their Dynamat Xtreme material also comes in convenientlypre-cut shapesfor thedoors,speakers, and various other areas.

In addition to the Dynamat Xtreme packs, this company also makes several other insulating materials. For one, they have several options for people looking to prevent engine overheating with their hood liners.

Dynaliner is a synthetic rubber foam product that can be installed inside of the car doors or under the hood. If you often worry about having your fluids evaporate which is a common side-effect of leaving your car in the sun consider installing a self-adhesive hood liner.

Dynamat offersthree 32 by 54-inch products of varying thicknesses. They have thequarter-inch thickDynaliner, ahalf-inch one, andthree-quarters of an inchHoodliner. Any one of these would be able toprevent your engine or your cabin from overheatingif used correctly. However, you ought to keep in mind that Dynalinerisnt waterproof.

Fortunately,the company does make a product that is waterproof.Dynapadis an almosthalf-inch thick non-adhesiveproduct that also comes in32 by 54-inch sheets that should cover 12 square feet. Since this product cant stick to a surface, youll either have to tape it in place or hold it down. After all, Dynapad should go onto the floor of the car, so you can basically just drop it in place and cover it up with your rubber floor mats and carpeting.

If this were an official popularity ranking, these next few products would be sharing the third place. Hushmat is aneven less expensive alternativeto products from the previous two brands. The material ispure butyl, so you can expect ahigh degree of heat resistance and sound control.

In fact, according to the manufacturer, Hushmat is supposed to be very easy to mold to the lines of a vehicle. Itshould also be able to withstand temperatures between minus 30 and 400 degrees Fahrenheitand evenreduce heat by up to 40% which is admittedly impressive. The fact that many users agree with the companys assessment of their products abilities is even more promising.

However, unlike the previous brands Ive mentioned, Hushmat doesnt really have a wide assortment of different products. Their most popular product is certainly the10-piece door kitwhich is actually just a regularblack foil kit of 12 by 12-inch square pieces. You can cut them into whichever shapes you need them to be, so theres nothing that prevents you from utilizing this door kit elsewhere.

Still, keep in mind that insulating an entire vehicle takes about 36 square feet, so this 10 square foot kit isnt likely to be enough. Instead, youd do well to purchase one of their bulk kits, such as this30-sheet 58 square foot one. And for smaller projects, though, they also make aregular 4-piece kitas well as a4-piece speaker set.

Kilmat is probably one of the most understated products Ive ever heard of. Not only is itaffordable, but its also agreat solution for lessening rattling and vibration noises. Of course, since the adhesive back ispure butyl, its extremely heat-resistant.

Like Noico,Kilmats 80 mil mathas arectangular relief pattern on the silver foil side of the product thatll come in handy when you buff it in. The pack Ive linked tocontains 9 sheets that are about 19.5 by 15 inches in size. So the pack would be enough to cover the 18 square feet surface inside of an average passenger car.

The one complaint Ive seen about this particular product is that itcan be a bit tough to cut through. However, many people have said the same about Dynamat, and its still one of the most effective products on the market.

Still, if you dont want to bother cutting through 80 mils of butyl, you can always get one of the50 mil packs. One of them is enough to cover50 square feet, and the other is suitable for surfaces that arehalf that size. The 80 mil product would certainly be more effective, though.

Fatmat has been making exemplary automotive insulation materials for years now, but if I had to pick a single product out of their lineup, Id go for the80 mil RattleTrap mat. The18-inch wide material comes in a 33.5-foot long roll, though you can actually choose the square footage you need. The specific product Ive linked to here alsocomes with instructions, a knife, a buffing roller, and a brand stickerfor your car.

According to the brand,Fatmat products use a patented rubberized compound although they havent stated that its butyl-based. Still, its supposed to beheat-resistant and completely odorless. So that gives us more clues about the base materials they used. Like other similar products, this one is supposed to cut down on noise and make your car more bearable in extreme weather.

However, thats not the only kind of product Fatmat makes. Indeed, their other products may be even more impressive. For example, theFatmat hood lineris a34 by 54-inch foil and foam product thats meant to reduce engine noise and overheating. The mat isthree-quarters of an inch thick, so it should effectively protect the paint on your hood from peeling due to the excess heat coming from the engine.

On the other hand, if youve noticed that most of the AC air is escaping through the floor of your car, you can also use theFatmat floor kit. These rubber-basedquarter-inch thick 24 by 54-inch piecesshould provide sound absorption as well as thermal insulation.

Now, these next few brands arent exactly at the top of anyones list, but I thought they deserved some recognition too. The B-Quiet insulation is one of thelesser-known butyl-based sound deadening mats, but its certainly worth checking out, if only for its price.

The company makes incredibly affordable45 mil mats, whichobviously arent the most effective option. According to the company, that material is actually a rubberized asphalt compound, which means that its probably not the best at thermal insulation.

Still, it should make a noticeable difference in your vehicle, especially when used in combination with theB-Quiet Vcomp composite noise barriers, as per the recommendation of the manufacturer.

On the other hand,if you want something more substantial, you can also get a much more sensible60 milmaterial. The product description states that theviscoelastic deadener has a supercharged butyl-based adhesive, which also doesnt rule out the presence of asphalt. Still, even though reviews of this product are fairly sparse, theyre also overwhelmingly positive.

Siless is the one brand that kept popping up while I was researching products that exist on theintersection of affordability and efficacy. The brand likely isnt one youre familiar with, but thats exactly why I included it here. Their80 mil matis actuallyvery similar to Noico, so you can expect a similar performance.

Theyre bothbutyl materialsof the same thickness. Therefore, we can assume that both canachieve similar resultswhen it comes to sound deadening and thermal insulation. As far as I can tell, the only difference is that the Siless mat comes inpacks of 7.5 square feet, so youll have to place your order with that in mind.

Like Noico, the Siless mat even has atextured foil front, which makes it easier to see which parts of the material have been buffed into the surface youre working on. According to users, this product is very easy to apply, and it settles into the contours of the metal perfectly.

The Q-Mat by SoundQubed is another great option for those looking for a thickbutyl-based insulation mat. When I first found this mat, I dug into the companys other products, as I always do. Consequently, I found out thatSoundQubed is primarily a manufacturer of automotive sound systems.

That piece of information made me feel very optimistic about the quality of their sound deadening mat. But could this thing handle the heat?

Well, since this mat is an86.6 mils thick pure butyl rubber(with the addition of theblack aluminum front), Id say that the answer is: yes. In fact, it should do just about everything youd want your mat to do:reduce rattling, vibrations, and road sounds, as well as regulate heat.

The Q-Mat comes in16 square foot rolls. If you decide to go all in with it, youd have to order at least two packs. Overall, customer satisfaction seems to be high, so I felt compelled to mention this insulation mat on my list.

Now if you dont really trust 80 mil mats to do a good job of heat and soundproofing your vehicle try this mat one for size. The two Uxcell products that caught my attention are bothupwards of 300 mils (or 0.3 inches) thick.

The thinner one of the two is315 milsthick and contains only one40 by 24-inch pieceof material. That only covers6.5 square feet although you can also get a pack of 2 pieces. Because this product has anadhesive layer, you canuse it on the hood, the ceiling, the doors, the floor, and wherever else you can think to place it.

The mat is made of adense, waterproof cotton foamand it has a strong black glue in the back. Despite its thickness, itshould be easy to cut and install. But this product isnt even the thickest one in the companys lineup.

Instead, that honor goes to their most popular product on Amazon, the394 mil mat. According to the company, that product isheat and scratch-resistant, in addition to beingwaterproof. It also comes in rolls thatcover either 16 or 33 square feet, so there should be enough of the material to go around. If youre unconvinced by the thickness of the other products Ive mentioned, these two should prove to be great replacements.

Finally, lets talk about thenewest addition to our roster of automotive insulation products liquid insulation. Ive already said a few things about how these kinds of products work, but lets reiterate before we go into the specific brand that made it famous.

Basically, you get a gallon or a2-gallon bucketof the stuff, mix it up with a drill bit, and pour some of it into aspray gun powered by an air compressor. From there, you cangive your vehicle two or more passes until you apply about 40 milsof the product.

Typically, a1-gallon bucket would be enough to cover a surface of about 25 square feet. So a 2-gallon bucket should be enough to cover vehicles of all sizes. You can learn more about the application process and the Lizard Skin insulation inthis video.

In short, because were dealing withceramic insulation, you can expect a huge improvement in your carsheat-resistance. Itll definitely keep cool in the summer and hold the AC heat inside during winter.

Personally, Im less than impressed with its soundproofing capabilities. Im sure thats only becauseI suspect that once the layer of insulation hardens, it wouldnt be able to provide the padding a foam or rubber-based mat might provide. Still,the additional thickness alone should be enough to cut down on the exterior sound, at least. As for the rest you could always apply a bit of finishing tape to keep various pieces from rattling.

At this point, I ought to reiterate thatthe rollers and the tapes arent unavoidable parts of the mat installation process. The rounded handle of a screwdriver or simply rubbing the mat in with your hands would work just as well. Many materials also havepatterns in the foil that flatten out as you buff them in. So you should have a pretty good idea of how well the installation process is going.

Of course, all this assumes that youre going to use the sound deadening mats to insulate your car. However, that may not be the case. Its possible that another type of insulating material has caught your eye.

Even though spray insulation hasnt been around for a long time, its definitely promising. At the very least, you wouldnt have to worry about the product sticking to your clothes.

Hopefully, this article has given you a few ideas about your automotive insulation. Installing one of the products Ive told you about here is sure tolessen the amount of noiseyoure experiencing. Best of all, itll evenprotect your car from the heat and just in time for summer!

Great research and thanks for the info.
