Photo Report of Completed Work
A Toyota Camry came to our installation centre with complaints of road noise from the wheels, high vibration levels, and excessive internal and external noise. After inspection, we recommended our Ultimate sound deadening package, including external wheel arch treatment.
Roof Sound Proofing

After removing the headliner, we degreased the roof metal and installed STP Diamond vibration damping material, followed by STP Biplast as the sound-absorbing layer.

Floor Sound Proofing
We disassembled the interior, removing the seats and floor coverings. The surface was then cleaned of dust and thoroughly degreased.

The first layer installed was STP Bimast Bomb Premium vibration-damping material. The second layer consisted of sandwich materials: STP Sonora under the front seats, STP Bromo under the rear seats and along the central tunnel.

Boot Sound Proofing
We disassembled the trunk and found only small sections of factory sound insulation, which are insufficient for proper noise reduction. For maximum effectiveness, the trunk must be fully treated, including the wheel arches.

Boot Sound Proof

We cleaned the metal and treated it with a degreasing agent. We then installed vibration-damping materials. Using our Ultimate package, STP Bimast was applied to the main surface of the trunk and arches, and STP Diamond in the spare wheel well. We also treated the fenders with STP Diamond.

Boot Sound Proof

The next step is treating the trunk with STP Bromo sandwich material. This stage is especially important due to the proximity of the speakers.

The material combines sound insulation and sound absorption properties, reducing unwanted acoustic reflections and improving sound clarity.

Boot Lid Sound Proof

We also performed vibration-damping treatment on the trunk lid. There is no factory sound insulation in this area, so the metal was cleaned and thoroughly degreased.

STP Diamond vibration-damping material was pre-cut to match the required sections and then installed on the trunk lid. The reinforcement ribs were left uncovered, as their thickness provides sufficient rigidity, and additional vibration damping is not required.

Boot Lid Sound Proof

We installed STP Biplast sound absorber on the plastic trim panel. The surface was degreased beforehand, and the material was applied without excessive stretching.

Doors Sound Proof

We disassembled the door using plastic trim removal tools and inspected the inner surface. There is no factory sound insulation in this area, so we proceeded directly to cleaning and thoroughly degreasing the metal to ensure proper adhesion of the vibration damping material.

Doors Sound Proof

We applied STP Diamond vibration-damping material to the metal surface. It was installed between the reinforcement ribs and terminated 3 cm above the lower edge of the door to keep the drain holes unobstructed.

Doors Sound Proof

Over the vibration damping layer, we installed STP Sonora sandwich material based on foamed polypropylene. The material combines sound absorption and sound insulation properties, helping absorb internal noise and improve speaker acoustics while reducing external noise transmission into the cabin.

Hood Sound Proof

Engine vibrations are transferred to the hood and then into the body structure, reducing cabin comfort. To address this, we installed STP Diamond vibration damping material on the hood, pre-cut to fit the required sections.
The reinforcement ribs were left uncovered, as their rigidity provides sufficient structural support and additional damping is not required.
