Photo Report of Completed Work
A Toyota Camry arrived at our installation centre with complaints of road noise from the wheels, a high level of vibration, and both internal and external noise. Following inspection, we decided to carry out soundproofing using our Ultimate package, including external treatment of the wheel arches.
Roof Sound Proofing

After disassembling the roof and removing the headliner, we degreased the metal and installed STP Diamond along with STP Biplast as a sound absorber.

Floor Sound Proofing

We dismantled the interior floor, removed the seats and floor coverings. After that, we cleaned the surface from dust and degreased it. We installed the first layer of vibration damper StP Bimast Bomb Premium, and the second layer was sandwich materials: under the front row Sonora, under the back and along the central axis - Bromo.

Boot Sound Proofing
We disassembled the trunk. Here you can see fragments of the factory soundproofing, but it is not enough to protect against noise. To ensure the full effect, it is necessary to roll up the trunk completely, 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 stage is treating the trunk with Bromo sandwich material. This stage is especially important because of the speakers' proximity. The material combines sound insulation and sound absorption, dampening unwanted acoustic waves and cleaning up the sound.

Boot Lid Sound Proof

We also did vibration isolation of the trunk lid. There is no factory noise insulation here, all that is left is to clean and degrease the metal. We installed vibration-absorbing material StP Diamondon the trunk lid, having previously cut it to the shape of the areas that we will be processing. The stiffening ribs are thick enough and do not need vibration isolation, so we do not touch them.

Boot Lid Sound Proof

We installed STP Biplast sound absorber on the plastic trim. We degreased the plastic beforehand, then applied the sheet material without stretching it.

Doors Sound Proof

We disassembled the door using plastic trim tools. We inspected the inner surface. There is no factory noise insulation here, so we proceeded directly to cleaning and degreasing the metal to ensure good adhesion with the vibration damper.

Doors Sound Proof

We applied the StP Diamond damper to the metal surface. It is mounted between the reinforcements and should end 3 cm above the lower edge of the door. This is necessary so that the drainage holes remain open.

Doors Sound Proof

On top of the vibration insulation, we installed a Sonora sandwich material based on foamed polypropylene. This material provides a dual function: it absorbs noise in the cabin and from the speakers, and also reflects external sounds.

Hood Sound Proof

Vibrations from the engine are transmitted to the hood and then to the body, making the cabin uncomfortable. To solve this, we installed STP Diamond vibration-absorbing material on the hood, pre-cutting it to fit the areas we processed. The stiffening ribs are thick enough and do not need vibration isolation, so we left them untouched.
