Application Process

Applying sound deadening mats is something that you might need to spend a certain amount of time on. While this is typically an easy process, it’s often time-intensive, so you’ll need to put a few hours aside to do so.

When you’re applying it, you’ll need to make sure that you’re placing it on the metal that you want to soundproof. This could mean that you’ll have to remove seats and a few other things, which is the main reason that this can be a time-intensive process.

Once you’ve done this, you’ll need to make sure that you put on some protective gear, such as gloves. This is because both asphalt and butyl are tacky, which could mean that they’ll stick to your hands quite easily. Alongside this, you could get somewhat dirty when you’re applying them.

As such, it can often be recommended that you wear protective gloves and clothes that you don’t mind getting dirty. After this, it should be a matter of cutting your sound deadening mat into the shape and size that you’ll need.

While this could take a large amount of time, it shouldn’t be too difficult to apply. Typically, you’ll be able to install the sound deadening mat on any area in your car, some areas might be slightly difficult. Perhaps the largest of these are the doors, although every other area should be quite easy.

Typically, you’ll simply need to roll the mat against the area that you want to apply it to, with many products having self-adhesive properties.

How Do Sound Deadening Mats Work?

Many of us might wonder how sound deadeners actually work. This is mainly because some people might see them as a relatively thin piece of fabric that covers an area. However, they’re much more effective than you might think, with the products working in a few notable ways.

Essentially, these work by gripping any metal surfaces and making them sturdier and thicker. This should mean that much less noise should be able to travel through them. Alongside this, you should be able to see much less rattling from certain parts of your vehicle, which helps to reduce sound levels further.

Sound deadening mats should also prevent the metal from vibrating as much as it used to. To properly achieve this, however, there are a few things that you’ll need to pay attention to. Typically, you’ll need to put the mats on at least 25% of the area of your vehicle.

However, placing it on as much of the metal as possible should help to increase the sound absorption. There are also a few other factors that you’ll have to pay attention to when putting down the sound deadening mats.

One of the more prominent comes when you’re choosing which product to buy. Thicker ones should offer much more sound absorption than thinner models, which makes them much better-recommended.

Butyl Vs Asphalt Sound Deadening Materials

You might wonder whether you should choose either a butyl or asphalt sound deadener, as both offer various pros and cons. Typically, these will be used as the base material in many products, which is where the majority of differences between them will be seen.

However, many of us might wonder what these differences actually are. In the majority of cases, products that use an asphalt base will be slightly thicker than their butyl counterparts. Alongside this, the majority of them should be much more affordable, which many of us might find appealing.

Despite this, asphalt sound deadening mats can often produce somewhat of a smell once it’s been put down. While this should fade over time, it’s something that many of us will want to avoid.

If you’re considering a sound deadening mat, then there are a variety of factors you’ll have to look at. While the material that it’s made from will play a certain role, you should look at each of the other pros and cons of that specific product first to help make your decision.

Butyl Vs Asphalt: The Final Tally

In the majority of cases, you might find yourself gravitating toward butyl instead of asphalt. This is mainly because of the benefits that butyl has over the alternative, the majority of which you should find appealing.

For example, asphalt shouldn’t be able to put up with high temperatures, which could be a notable issue for many areas of your car. Alongside this is the fact that butyl sound deadener mats should offer much more sound absorption than its counterpart, with this being driven by how thick it is.

Coupled with this is the fact that butyl doesn’t have an odor when it’s applied to a car, which is a noticeable problem for many of us. However, this doesn’t mean that the material doesn’t have its flaws, as it does have a few.

Despite this, these are all relatively minor and pale in comparison to the drawbacks that asphalt can have. This has led to an increasing number of manufacturers choosing to use butyl instead.

While asphalt sound deadening mats are much more affordable than their butyl counterparts, they’ll often be of a lower quality. As such, it’s recommended that you go for a slightly more expensive option. This should mean that you’ll get much more value for your money and not have to replace the mats anytime soon.
