Vehicle soundproofing

Car vibration and soundproofing eliminates annoying street noise, squeaks, and vibrations from doors, wheel arches, the trunk, roof, and floor of your car once and for all! You’ll be able to enjoy high-quality music, have clear phone conversations, or simply enjoy the silence—making your driving experience significantly more comfortable!

At Brooklands Detailing, we offer professional vibration and soundproofing services for the following areas:

• Doors and interior panels: This will protect against external noise and create a sealed acoustic environment. The process is done without complicated disassembly of parts.
• Car floor (underbody): Modern factory carpets do not shield the car from road noise, suspension sounds, or vibrations. This service not only reduces noise and vibration but also helps retain heat and maintain a comfortable cabin temperature.
• Trunk: Popular for hatchbacks, station wagons, and cars with sporty exhaust systems. The process reduces noise from the rear suspension, exhaust system, and wheel arches.
• Wheel arches (inner fenders): The wheels are removed, and the inner plastic wheel wells are cleaned. This is one of the most common services, ensuring a more comfortable driving experience.
• Roof: The thin roof frame can make noise during heavy rain, hail, or from passing vehicles. In addition to reducing noise, the material has excellent thermal insulation properties.
• Hood: It’s best to do this alongside engine compartment soundproofing to completely block out engine noise.
• Dashboard: Soundproofing of the dashboard to reduce vibrations and noise within the cabin.

At Brooklands, our experts use only genuine soundproofing materials from Comfort Mat. These materials are durable and come with a long manufacturer’s warranty.

We offer two options for insulation services:

• “Optimal” Package using Comfort Mat G-Line: These vibration-damping materials are designed to absorb and dissipate various types of sound and vibrations. The composition includes a new-generation G-formula mastics and HotAl aluminum foil using the InFliz technology. Recommended for areas with medium to high vibration loads. After soundproofing, the car’s weight increases by approximately 70 kg.

• “Premium” Package using Comfort Mat D-Line: This is a premium vibration-damping material made from D-formula mastic using the multi-stage low-temperature mixing DarkAi technology, as well as HotAl aluminum foil using the InFliz technology. The vehicle’s weight increases by only 30 kg, which is 35% less than other materials. Recommended for use in areas with high vibration loads.

On average, soundproofing individual car parts takes around two hours, while full soundproofing takes about a full day.

The comfort of a car ride depends on many factors, with cabin soundproofing being one of the most important. Car manufacturers are well aware of this, but to save costs and reduce the overall weight of the vehicle, they typically use a minimal set of available materials. In fact, high-quality soundproofing can significantly raise the cost of materials and labor, which can increase the final price of the car. In industrial production, this can lead to huge additional expenses. However, not all car owners are willing to tolerate the acoustic “concert” that accompanies every drive in their favorite vehicle.

 

What is proper soundproofing in a car?

When done according to the right technique, soundproofing can reduce the overall level of noise entering the cabin by at least 50%. This includes not only soundproofing but also vibration isolation, which helps eliminate the resonance caused by strong vibrations from various parts and mechanisms of the car. Professional car soundproofing involves treating all components that can produce or transmit sound vibrations—such as the engine, trunk, floor, roof, ceiling, interior, wheel arches, doors, and more—with specialized materials.

Who should perform the car soundproofing that significantly increases comfort while driving?

While many car owners attempt this task themselves by purchasing ready-made soundproofing kits, the results are often disappointing. This is typically due to mistakes in applying vibration dampers and sound absorbers. Considering that doing it yourself, including buying all the materials, doesn’t save much compared to professional services, it raises the question: is it worth spending money on subpar results? There are two key factors for success in this job: choosing the right materials and applying them properly to the vehicle’s surfaces. What will this approach achieve, and how do professionals accomplish the task?

Why trust professionals with your car soundproofing?

Experienced specialists know there’s no universal soundproofing material that can block all types of sound waves effectively. The solution is simple: professionals create a "sandwich" of several materials, each contributing to the overall soundproofing. Vibration dampers, soundproofing materials, sound absorbers, and anti-squeak materials are placed in a specific order and in the right spots to eliminate as much noise and vibration as possible.

Understanding the technology of wheel arch treatment:

The process involves several steps: removing the plastic inner fender (carefully keeping all fragile clips!), cleaning, washing, degreasing, and drying the surface, applying polymer mastic and hardener, and then carefully reinstalling the fender. This also involves selecting the right isolating materials and determining the appropriate amount to avoid overloading the car’s bodywork. Does this sound complicated? A professional’s job extends beyond just the wheel arches—it's also about treating the doors, floor, engine compartment, and dashboard, with every part being disassembled and treated properly.

Cost of full car soundproofing:

The price for a full car soundproofing service is based on the specialist's labor (typically around 6-7 hours for a passenger vehicle) and the cost of materials. The materials are carefully selected to account for the specific characteristics of each part of the car’s body and the sound waves they transmit. For example, for doors, the "sandwich" might include a 2mm vibration damper, a 10mm sound absorber with a waterproof sealant, a vibration- and moisture-proof layer to seal existing holes, and an additional layer of sound absorber. Each part of the car body has its own "layered recipe," and together they create an impressive result: imagine cutting the noise entering your cabin by half!

This procedure will guarantee improved acoustic characteristics inside the cabin, making the driving experience more peaceful and comfortable for both the driver and passengers. It will also extend the lifespan of the vehicle due to the moisture-resistant properties of the materials (protecting against corrosion) and improve the vehicle’s thermal insulation.
