Car Floor Soundproofing Kit – Reduce Road, Tyre & Highway Noise Upgrade your vehicle with a professional-grade floor soundproofing kit designed to reduce road noise, tyre noise, engine noise and highway drone while improving overall cabin comfort. This kit combines StP Aero vibration damping with StP NoiseBlock 2 sound barrier material to create a high-performance 2-layer floor insulation system for serious noise reduction. What's Included in the Kit StP Aero lightweight vibration damping material StP NoiseBlock 2 high-density sound blocking material Professional 2-layer floor soundproofing system Designed for road noise, tyre noise and cabin noise reduction Key Benefits Reduces road noise from the floor Reduces tyre noise and highway drone Helps block engine and drivetrain noise Improves long-distance driving comfort Creates a quieter, more premium cabin feel Improves audio clarity by reducing background noise Why This Kit Works The floor is one of the biggest sources of road noise inside a vehicle. Noise from tyres, road surface and drivetrain vibration travels through the metal floor and into the cabin. This kit uses a proven two-layer soundproofing system: StP Aero reduces metal floor vibration and resonance StP NoiseBlock 2 adds mass and blocks airborne road noise from entering the cabin Together, these materials create a quieter cabin and a more comfortable driving experience. Layer 1 – StP Aero Vibration Damping StP Aero is a premium lightweight sound deadening material designed to reduce panel vibration without adding unnecessary weight. Thickness: 2.3mm Coverage per pack: 4.5m² 12 sheets per pack Sheet size: 750 × 500mm Weight: up to 3.5kg/m² Temperature resistance: -45°C to +100°C Strong permanent adhesive Non-flammable construction StP Aero is applied directly to the vehicle floor metal to control vibration before it becomes cabin noise. Layer 2 – StP NoiseBlock 2 Sound Barrier StP NoiseBlock 2 is a high-density sound blocking material designed to stop road, tyre and engine noise from entering the cabin. Thickness: 2.0mm Coverage per pack: 1.99m² 10 sheets per pack Sheet size: 350 × 570mm Weight: ≥ 4.0kg/m² Noise reduction: ≥ 30dB Temperature resistance: -45°C to +100°C Non-flammable and safe for interior use NoiseBlock is installed as the second layer over StP Aero to create a dense sound barrier between the road and the cabin. Installation Guide Remove seats, carpet and required interior trim Clean and degrease the vehicle floor thoroughly Apply StP Aero directly to the metal floor Roll firmly using a sound deadening roller Apply StP NoiseBlock 2 over the vibration damping layer Refit carpet, seats and trim DIY Installation Time: approximately 4–8 hours depending on vehicle size and interior complexity. Best Areas to Install Front floor area Rear passenger floor Transmission tunnel Under rear seats Boot / trunk floor Interior wheel arches Who Is This Kit For? Drivers bothered by road noise People wanting a quieter daily driver Performance car owners wanting lightweight damping 4WD and SUV owners seeking better comfort Long-distance travellers Anyone building a premium soundproofed cabin FAQ Will this floor kit reduce road noise? Yes. StP Aero reduces floor vibration, while StP NoiseBlock 2 blocks airborne road and tyre noise from entering the cabin. Is NoiseBlock better than normal sound deadening? NoiseBlock performs a different job. Sound deadening materials reduce vibration, while NoiseBlock adds mass to block sound. For best results, both layers should be used together. Can I install NoiseBlock directly onto the floor? It works best when installed over a vibration damping layer such as StP Aero. Will this kit improve highway comfort? Yes. The floor is a major source of highway and tyre noise, so insulating this area can noticeably improve long-distance comfort. Does it add much weight? StP Aero is lightweight, while NoiseBlock adds mass intentionally to block sound. This combination gives strong noise reduction while keeping the system efficient.
