StP NoiseBlock 2 – Car Sound Blocking Material for Floor & Cabin Insulation Australia

Looking for a powerful way to block road, engine, and tyre noise inside your car?

StP NoiseBlock 2 is a high-density automotive sound barrier material designed to stop external noise from entering the cabin. It adds mass to the structure — which is the most effective way to block airborne sound.

This makes it an essential layer in professional car soundproofing systems.


What Is StP NoiseBlock 2?

StP NoiseBlock 2 is a mass-loaded sound insulation material designed to block noise rather than absorb it. It is typically installed as a final layer on top of vibration damping and absorption materials.

This creates a sealed barrier that prevents sound from passing into the cabin.


Why Sound Blocking (Mass Layer) Matters

Most materials reduce vibration or absorb sound — but only dense materials like NoiseBlock can physically stop sound waves.

By adding mass, it:

  • Blocks low-frequency road noise
  • Reduces tyre and engine noise
  • Seals the cabin from external sound

This is what creates a truly quiet and premium driving experience.


How Much Coverage Do You Get?

One pack (10 sheets, 1.99 m² total coverage) is enough to:

  • Insulate the front passenger floor or boot
  • Cover wheel arches and under-seat areas in a mid-size vehicle

Ideal for floor sound insulation and cabin sealing.


Where to Use StP NoiseBlock

  • Interior floor (main road noise source)
  • Wheel arches (inside cabin)
  • Boot / trunk floor
  • Under rear seats

Best used as a final layer over damping and absorption materials.


Why StP NoiseBlock 2 Works

  • High-density construction adds mass to block sound
  • Reduces road, engine, and tyre noise
  • Flexible design for easier installation
  • Heat and temperature resistant (-45°C to +100°C)
  • Non-flammable and safe for interior use

This makes it one of the most effective car sound blocking materials in Australia.


Performance Benefits

  • Significant reduction in highway noise
  • Quieter cabin at all speeds
  • Improved long-distance comfort
  • Better audio system clarity

Installation Guide

  • Clean and degrease the surface
  • Install vibration damping layer first
  • Add absorption layer if needed (Bromo / Accent)
  • Apply NoiseBlock as final layer
  • Use roller to ensure full adhesion

Tip: Works best above +15°C or with slight heating.

  • Sheet size: 350 × 570 mm
  • Thickness: 2.0 mm
  • Total coverage: 1.99 m²
  • Weight: ≥ 4.0 kg/m²

How to Use in a Sound Deadening System

  • Step 1: Vibration damping (StP Gold / Aero)
  • Step 2: Absorption layer (Bromo / Accent)
  • Step 3: NoiseBlock (final sound barrier)

This creates a complete multi-layer soundproofing system with maximum performance.


NoiseBlock vs Other Materials

  • Gold / Aero: reduces vibration
  • Bromo / Accent: absorbs sound
  • NoiseBlock: blocks sound completely

You need all three for the best result.


FAQ

Do I need NoiseBlock for full soundproofing?

Yes — without a mass layer, sound will still pass through the structure.

Where is it most effective?

Floor, wheel arches, and boot — main sources of road noise.

Can I install it alone?

It works best as part of a multi-layer system with damping and absorption.
