StP Accent 6mm & 10mm – Car Sound Absorption & Heat Insulation Material Australia

Looking for a material that reduces both noise and heat inside your car?

StP Accent is a premium automotive sound absorption and thermal insulation material designed to improve cabin comfort. It combines acoustic foam performance with heat protection — making it an essential layer in any professional sound deadening setup.

What Is StP Accent?

StP Accent is a self-adhesive acoustic insulation material made from foamed polyethylene. It is designed to absorb airborne noise and reduce heat transfer inside the cabin.

Unlike vibration damping materials, Accent works as a final comfort layer, improving overall sound quality and temperature stability.

What Does StP Accent Do?

• Absorbs airborne noise inside doors and panels
• Reduces echo and unwanted resonance
• Improves overall cabin acoustic comfort
• Provides thermal insulation (cooler in summer, warmer in winter)

It is one of the most effective car sound absorption materials available in Australia.

How Much Coverage Do You Get?

StP Accent 6mm

• 16 sheets (375 × 500 mm)
• Total coverage: 3.0 m²

StP Accent 10mm

• 10 sheets (375 × 500 mm)
• Total coverage: 1.87 m²

Typical applications include:

• All 4 doors (improves sound quality and reduces noise)
• Roof insulation (reduces heat and rain noise)
• Bonnet insulation (engine heat protection)

Where to Use StP Accent

• Doors (best combined with damping layer)
• Roof (heat + rain noise reduction)
• Bonnet (thermal insulation)
• Floor (additional comfort layer)

For best results, install on top of vibration damping materials (StP Gold, Aero, etc.).

Why StP Accent Works

• Multi-layer construction: protective top layer + foam core + adhesive base
• Sound absorption improves acoustic comfort
• Thermal insulation reduces heat transfer
• Waterproof – ideal for doors and humid areas
• Strong adhesion to metal and damping materials
• Flexible for complex shapes and tight spaces

This makes it a key component in full car soundproofing systems.

Installation Guide

• Clean and degrease the surface thoroughly
• Apply on top of vibration damping layer
• Cut to size, peel backing, and press firmly
• Ensure full contact, especially on curved surfaces
• Minimum bend radius: 100 mm

Accent 6mm vs 10mm – Which to Choose?

• 6mm: best for doors and tight spaces
• 10mm: maximum sound absorption and heat insulation

Choose based on available space and desired performance.

How to Use in a Sound Deadening System

For best results, combine Accent with:

• Step 1: Vibration damping (StP Black Gold / Aero)
• Step 2: Sound barrier (NoiseBlock)
• Step 3: Accent (final absorption layer)

This creates a professional multi-layer soundproofing system for maximum noise reduction.
