Photo Report of Completed Work
Roof Sound Proofing
The roof of the Subaru Forester is a large, relatively thin panel that allows wind and rain noise to easily transfer into the cabin — especially at higher speeds.
To address this, we apply a lightweight yet highly effective STP Gold 2.3mm vibration damping material, designed to reduce metal resonance and stabilise the roof panel, resulting in a quieter and more refined driving experience.
As a sound and heat protection we installed StP Accent 10mm

Floor Sound Proofing
The floor was treated with STP Gold 2.3mm , a high-efficiency vibration damping material designed to handle large, flat metal surfaces exposed to constant mechanical and road impact.
Floor Sound Proofing
On top of the 1st layer we installed StP Noise block to stop medium and high frequency noise
To stop any noises in plastic contacts it's required to wrap it with StP Biplast 5mm/10mm/15mm
The doors of the Subaru Forester were treated with a two-layer system — STP Gold 2.3mm as the base vibration damping layer and STP Sonora as the acoustic absorber.
This combination eliminates metal resonance, door panel rattles, and external noise from passing traffic or tyres.

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