Description
A Caliber 2mm damping sheet is a soundproofing and vibration-dampening material used to reduce noise and enhance audio quality in vehicles. Like other similar products, it is a universal, self-adhesive sheet that can be installed on various parts of a car to improve the cabin’s acoustic and thermal insulation.
How it works
Damping sheets like the Caliber 2mm product function by adding mass to a vehicle’s panels, which reduces vibration and resonance.
- Vibration reduction: The core material is typically a butyl rubber compound with an aluminum foil facing. This dense, viscoelastic material is designed to convert vibrational energy from the car’s engine, road, and speakers into low-level heat, preventing panels from rattling.
- Noise insulation: By controlling these vibrations, the sheets block unwanted road and engine noise from entering the car’s interior, creating a quieter and more pleasant driving experience.
- Audio enhancement: Damping sheets are especially popular with car audio enthusiasts because they significantly improve the clarity and quality of sound from the vehicle’s speakers by eliminating panel distortions.
- Thermal insulation: The materials also offer thermal resistance, which helps to maintain a stable temperature inside the cabin, insulating it from external heat or cold.
Where to install
These sheets are commonly applied to metal surfaces inside a vehicle, including:
- Doors: Reduce wind and road noise and improve speaker performance.
- Floor and roof: Blocks road noise and minimizes turbulence sounds.
- Trunk and wheel arches: Minimizes tire and road noise.
- Firewall: Reduces engine noise from entering the passenger compartment.
Universal fit: The sheets are designed to be cut to fit any vehicle.
Thickness: 2mm (or 80 mils) is a common and effective thickness for a good balance of dampening performance and added weight.
Installation: Installation is a do-it-yourself project but requires careful surface cleaning, measuring, and applying firm, even pressure with a roller to ensure proper adhesion and eliminate air bubbles.
