It reduces vibrations, improves audio system preparation, and protects against external noise intrusion.
Roof Sound Proofing
We removed the roof lining, then cleaned and thoroughly degreased the metal surface. This ensures proper adhesion of the vibration damping material.
Roof Sound Proofing
It effectively reduces resonance and the “drum effect” while maintaining a lightweight structure. At +10°C, it provides a KMP value of 0.33.
Roof Sound Proofing
The second layer is the STP Biplast sound absorber. Its advantages include high sound absorption performance and resistance to stretching and deformation during installation.
Floor Sound Proof
The floor has factory noise insulation installed. It is removed before applying the STP vibration damping layer, as it reduces adhesion.
Floor Sound Proof
In place of the factory material, we install STP Diamond vibration damping. With a KMP value of 0.6, it effectively reduces resonance in high-load vibration areas, improving overall ride comfort.
Floor Sound Proof
We use a combination of materials: the Qattara sandwich is installed under the front seats, while the Bromo sandwich is applied under the rear seats and on the central tunnel.
Boot Sound Proof
The boot is a direct continuation of the cabin, and the same sound insulation principles apply here. First, we remove the factory material, then clean and thoroughly degrease the surface.
Boot Sound Proof
We install STP Aero vibration damping on the wheel arches. It reduces resonance and improves the structural stability of the panels.
Boot Sound Proof
We install STP Biplast Premium 15A (Armor) as the top layer. It maintains its shape well, does not interfere with interior reassembly, and completes the acoustic treatment of the cabin.
Doors Sound Proof
We dismantle the doors, removing the speakers, trim panels, and factory moisture barrier.
Doors Sound Proof
We clean the inner door metal surface from dust and dirt, then degrease it thoroughly.
Doors Sound Proof
We install STP Aero vibration damping material between the reinforcing ribs. Its low weight ensures effective vibration control and reduces structural vibrations, including low-frequency resonance.
Doors Sound Proof
It also reduces noise transmission from the road, resulting in a quieter and more comfortable cabin.
Doors Sound Proof
We seal the service holes with STP Aero vibration damping material. It acts as a moisture and vapour barrier and creates a sealed acoustic enclosure. The speaker is then reinstalled in place.
Doors Sound Proof
We install STP Biplast sound absorber over the factory material. We maximise coverage while leaving clearance for the speaker.
