Sound & thermal insulation for cars and car audio

Improve the acoustic comfort and performance of your audio system with our soundproofing sheets, Alubutyl, acoustic foam, multi-layer insulation, and kits for doors, trunks, floors, and body panels.

CAR SOUNDPROOFING

Reduce vibrations, resonances, and unwanted noise

Automotive soundproofing treats different parts of the vehicle to limit panel vibrations, certain resonances, and noise transmission. In car audio, it also helps create an environment more conducive to speaker performance.

SOUNDPROOFING MATERIALS

Which insulation should you choose for your car?

Not all materials serve exactly the same purpose. A complete installation may combine several layers to address vibrations, noise, and contact between trim panels.

Alubutyl sheets

Butyl- and aluminum-based sheets are primarily used on metal surfaces to dampen their vibrations and limit certain bodywork resonances.

Acoustic foam

Acoustic foam is used as a complementary layer in different areas of the vehicle. Depending on its design, it can help with acoustic treatment and limit contact or noise between components.

Multi-layer insulation

Multi-layer materials combine several properties in a single product and can simplify certain acoustic treatments depending on the area of the vehicle.

Thermal insulation

Some products are specifically designed to complement the vehicle's thermal treatment. Their use depends on the area being treated and the material's characteristics.

CAR AUDIO SOUNDPROOFING

Why soundproof doors for car audio?

A car door consists of large metal surfaces and trim panels that may vibrate. Treating the sheet metal and trim can reduce unwanted vibrations and provide more stable support for the speaker. This is particularly beneficial when replacing the original audio system.

AREAS TO TREAT

Where should soundproofing be installed in a car?

Doors Speakers & vibrations
Trunk Subwoofer & bodywork
Floor Road noise
Trim panels Unwanted noise
DOOR SOUNDPROOFING

A particularly important treatment for speakers

Doors are often the first area treated during a car audio upgrade. Proper preparation helps limit vibrations and improve the operating conditions of the woofer or component kit installed in the door.

Anti-vibration door sheet metal

A damping material such as Alubutyl can be applied to metal surfaces to reduce their tendency to vibrate when the speaker is operating.

Trim & acoustic foam

A suitable second layer can be used behind certain trim panels to limit contact, vibrations, and unwanted noise, depending on the configuration.

CAR ALUBUTYL

Dampen bodywork vibrations

Alubutyl is widely used in automotive audio installations to treat metal panels. The collection includes different thicknesses and treatment surfaces, including CTK, Four-Connect, Hifonics, and Auto-Connect solutions.

CAR SOUNDPROOFING GUIDE

How to choose your soundproofing

Start by determining the area to treat and the problem you want to address: panel vibration, trim noise, door acoustic treatment, trunk treatment, or additional insulation. The material and its thickness must then be suited to the available space.

✓ Area — door, trunk, or floor
✓ Objective — vibration or noise
✓ Material — Alubutyl, foam, multi-layer
✓ Thickness — check the available space
✓ Surface — required quantity
✓ Installation — sheet or complete kit
Prepare the surface properly before installation.

For adhesive products, the surface must generally be clean, dry, and properly degreased. Then carefully apply the material to the intended area, following the manufacturer's recommendations. Good adhesion is essential for a long-lasting treatment.

DOOR SOUNDPROOFING KITS

Individual sheets or complete kits

The collection allows you to buy either a sheet for a specific area or sets designed to treat a larger surface. Specific door kits are also available to make a complete car audio installation easier.

Individual sheets

Practical for completing an installation, treating a small area, or testing different materials before performing more extensive soundproofing.

Door kits

Kits provide all the materials needed for door treatment and are an attractive solution when installing a new speaker kit.

FREQUENTLY ASKED QUESTIONS

FAQ – Car Soundproofing

What is car soundproofing used for?

It is used to treat certain vibrations, resonances, and noise transmission in different parts of the vehicle.

Why soundproof doors for car audio?

Door treatment reduces unwanted vibrations from sheet metal and trim panels and helps create a more stable environment around the speakers.

What is Alubutyl?

It is a damping material that generally combines a butyl-based layer with an aluminum sheet. It is commonly used to dampen vibrations from automotive metal panels.

Where can Alubutyl be applied in a car?

It can be used on various suitable surfaces, including door sheet metal, certain areas of the trunk or floor, depending on the product and the treatment's objective.

What is the difference between Alubutyl and acoustic foam?

Alubutyl is primarily used to dampen panel vibrations, while acoustic foam serves a different purpose and can be used as a complementary layer.

What insulation thickness should you choose?

It depends on the area being treated, the available space and the type of material. A greater thickness is not automatically suited to all areas of the vehicle.

Can you soundproof only the front doors?

Yes. For a car audio upgrade, starting with the doors housing the front speakers is a common approach before potentially extending the treatment to the rest of the vehicle.

Should you use several layers of insulation?

Several complementary materials can be used, as an anti-vibration layer and foam do not serve exactly the same function. The combination depends on the area and the desired result.

How many sheets are needed to soundproof a car?

It depends on the actual area being treated and the dimensions of the sheets. For doors only, a dedicated kit can make the calculation easier. For a complete vehicle, measure the different surfaces before ordering.
