Comparing Butyl and Asphalt Sound Deadening Solutions

Car sound deadening products can help your car in a lot of ways. If you want to improve the quality of your car audio while you are listening to your favourite tunes, then you must install some car sound deadening material. On the other hand, if you want to reduce the noise from the road itself, then you can also install this type of material.

The wonders of car sound deadening can intrigue a lot of us. However, the technology behind sound deadening solutions is quite simple. Sound deadening materials, such as mats, grip to any metal surfaces and make them sturdier and thicker. With thicker surfaces, the noise inside and outside your car won’t be travel through them. Moreover, certain parts of your car won’t rattle that much compared to a car without any sound deadening materials. 

Car sound deadening solutions can be formed by two materials: butyl and asphalt. These materials have their own characteristics and properties that may persuade you from buying one of them. After all, choosing and purchasing sound deadening solutions will rely on your final decision.

Butyl Sound Deadening Solutions

Sound deadening solutions that are made from butyl can effectively lessen the noise in cars. These solutions may be in the form of insulation pads and sound deadening sprays that can lessen the rattling noise generated by the metal frames of your car. 

Installing butyl sound deadening solutions can reduce any unwanted sounds on your vehicle, even if you only cover around 25% of your car’s surface area. Moreover, this material can also be more effective than any material by about 35%. 

In fact, different laboratory testings have proved that butyl-based sound deadening solutions have a 60% higher acoustic loss factor when the temperature is set at 86 degrees. When set at 104 degrees, butyl sound deadening solutions can deliver a whopping 72% better acoustic loss factor than asphalt materials. 

In day to day usage, butyl sound deadening solutions don’t emit an undesirable odour that is common with asphalt-based sound deadeners. Moreover, butyl materials can withstand issues of hardening and cracking. They also have a reduced adhesion when compared to asphalt-based materials.

Asphalt Sound Deadening Solutions

While the butyl material is fairly new, the use of asphalt has been going on for a long time. The original material used for sound deadening products and solutions is asphalt. This petroleum-based compound is effective in dampening sound in both freezing and normal room temperatures, so expect it to be also effective in your cars. 

Asphalt-based deadeners will not be as effective as butyl-based deadeners. At room temperature, the acoustic loss factor for an asphalt-based sound deadener has a value of 0.29. An acoustic loss factor of 0.14 is present when the temperature is set at 100 degrees. These values mean that the deadeners made up of asphalt are only working half as well at higher temperatures.

Asphalt sound deadening solutions that can be physically installed on surfaces of your car will be thicker than their butyl counterparts. Moreover, a lot of asphalt-based products are priced cheaper than other materials. A downside of asphalt, however, is it emits a strange odour whenever it is exposed to a very high temperature, particularly sunlight. Another disadvantage of asphalt is that it should not be installed if your car will always be exposed to high temperatures. 

Butyl and asphalt sound deadening solutions possess unique characteristics that can be beneficial for car owners. Both of these materials have properties that may attract one from buying them. If you have more questions about these two materials, you can give us a call now at All Car Carpets.
