The material is dense, flexible, and easy to cut, making it simple to line the inside panels. The adhesive backing grips firmly but still allows a bit of repositioning during installation—no messy glue required. Noise reduction is dramatic. After lining the enclosure, I measured roughly a 30–40% drop in operating noise, and the harsh high-frequency vibrations from stepper motors are almost gone. The printer now runs with a deep, muted hum, which is a huge improvement for a home office or shared workspace. The roll size (170 × 33 cm) was ideal—plenty to cover the P1S panels with some left over for small accessories. The 4 mm thickness strikes the right balance: thick enough to absorb vibration but not so thick that it interferes with door seals or airflow. Overall, the quality and performance are outstanding. If you want a quieter, more professional-sounding Bambu Lab P1S (or any 3D printer or enclosure), this AggSound sound-dampening material is a must-buy upgrade. ## Features - [Premium 4mm Foam] This 3-layer sound deadener blocks up to 98% of radiant heat and reduces road noise.

What's the best way to install it for maximum results?** A: 1.Remove & Clean: Take off interior panels; clean and dry surfaces 2.Cut to Fit: Pre-cut insulation for doors, floor, and roof 3.Apply & Seal: Peel, stick, then seal seams with foil tape (sold separately) 4.Reinstall: Replace all interior components **Q: What's the difference between Aluminum Foil and Closed-cell Foam?What are the best sound deadening solutions for sound?** A: 394mil Aluminum Foil excels in heat blocking. 157mil Closed-cell Foam (higher density) is better for soundproofing. For best results: combine 157mil foam with Butyl Sound Deadener (sold separately) to kill vibration and block noise effectively. **Q: How do I properly install the Butyl + 157mil High-Density Closed-cell Foam combination?** A: 1. Remove, Clean & Cut. 2. Apply butyl sheets(50–60% coverage is optimal), damping vibration, reducing low-frequency noise. 3. Install foam over butyl. Effectively blocks mid-high frequency noise. 4. Check. This combo ensures optimal noise reduction. **Q: How do sound deadening materials work to reduce noise? Can it reduce road noise? Can it be used on car doors?** A: Yes, Closed-cell Foam reduces road noise through:1.Sound absorption (energy to heat conversion) 2.Acoustic impedance reflection 3.Mass law blocking of mid-high frequencies. Its structure effectively reduces road/wind noise transmission into cabin. **Q: Does it require any special tools for the installation? Is a roller necessary?** A: Basic tools: gloves, utility knife, measuring tape. A roller (sold separately) is highly recommended to ensure proper adhesion of butyl/foam. Aluminum foil tape is essential for sealing seams. Keeping surfaces clean is crucial for optimal results. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super satisfaisant *by C***N on 16 April 2026* Isole super bien et supprime la condensation sur le plafond de mon local technique de piscine ### ⭐⭐⭐⭐⭐ Excellent Sound Dampening – Perfect Fit for My Bambu Lab P1S *by J***R on 11 September 2025* I bought this AggSound 4 mm sound-dampening roll specifically to quiet my Bambu Lab P1S 3D printer enclosure, and it exceeded expectations.
