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.

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.
