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. Technical Specifications Sheets: 10 Sheet size: 350 × 570 mm Thickness: 2.0 mm Total coverage: 1.99 m² Weight: ≥ 4.0 kg/m² Noise reduction: ≥ 30 dB Bond strength: ≥ 2 N/cm 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.
