It provides better noise insulation effect for your car so you can enjoy a more quiet and comfortable environment. At the same time, it effectively reduces 98% heat transfer. [High-quality Material, Meet the Needs of Longer & Better Use] 4mm high quality closed cell foam has a higher anti-extrusion function compared with inferior foam product, so there is no need to worry about the collapse of the use process. Excellent adhesive has strong viscosity, which can ensure to stick firmly. High quality back paper is easy to to peel & install and not easy to tear.[Equipped with High-quality Practical Tools, Ensure Convenient Installation & Insulation Effect][Easy to Install, Wide Application] Aggsound heat shied pad is convenient in installation and operation. Just five steps can be completed: disassemble-clean-cute-paste-reinstallate. 4mm unviersal thickness is more suitable for the car door, hood, trunk, floor, firewall and other parts of the vehicle. You do not have to worry about the phenomenon of not being able to install because the thickness is too large but the vehicle gap is not enough. Review: Works decently enough. A few things to note. It tears quite easily. It sticks to your fingers and will tear if you are not careful when tryin to remove. Once its stuck, its stuck. It will be messy to remove if needed. It looks a little like neoprene as some suggest it is, but it is not. Just a basic low grade closed cell foam. It does the job for sound insulating though! Review: Expensive but works like nothing else. Sure deadens sound on cab of ice cream truck. If you brush against it too hard it could tear or chip off but otherwise very durable. One inch thick and soft as a mat. ## Features - [4mm High Quality Closed Cell Foam, Provide Better Sound & Heat Insulation] Our automotive sound deadener is composed of three layers of high quality material, including 4mm high density closed cell foam, high quality back glue and back paper. - [Superior Noise and Heat Insulation] It provides better noise insulation effect for your car so you can enjoy a more quiet and comfortable environment.

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 ### ⭐⭐⭐⭐ Review *by N***L on 20 October 2025* Works decently enough.
