Roof Sound Proofing
The roof of the Land Cruiser 79 is one of the largest and thinnest body panels, making it a major source of wind and rain noise entering the cabin at higher speeds.
To address this, we applied a lightweight yet highly effective 2 mm STP Diamond vibration-damping material, designed to reduce metal resonance and minimise roof panel vibrations.

Roof Sound Proofing
All factory vibration damping was removed using dry ice to ensure a clean surface and maximum adhesion for the new high-performance materials.
Floor Sound Proofing
The floor was treated with STP Aerocell 6mm, a high-efficiency vibration-damping material designed for large flat metal surfaces exposed to constant road vibration and mechanical stress.
Floor Sound Proof
Benefits of Floor Soundproofing Reduces aerodynamic and road noise, creating a calmer cabin environment
Minimizes vibration load on the vehicle’s body, extending panel life and improving comfort
Dampens impact noise from gravel, sand, and uneven surfaces hitting the underbody
Improves thermal insulation, keeping the cabin cooler in summer and warmer in winter
This combination provides a noticeable upgrade in both acoustic comfort and driving feel, especially important for long-distance or off-road use of the Land Cruiser 79.

Doors Sound Proof
The doors of the Land Cruiser 79 were treated with a two-layer system — STP Diamond as the base vibration-damping layer and STP Sonora as the acoustic absorber.
This combination reduces metal resonance, door panel rattles, and external noise from passing traffic and tyre noise.

As a result, the doors now close with a solid, premium feel, and the cabin is noticeably quieter even at higher speeds.

Rear Wall
The rear cargo area had no insulation, so we installed sound and thermal insulation. The customer can now enjoy a more comfortable driving experience in his Land Cruiser.
