It provides a better effect of noise insulation for your car, so you can enjoy a quieter and more comfortable environment. At the same time, it effectively reduces 98% heat transfer. [High quality material, meet the needs of longer and better use] 10mm thickened foam has a higher anti-extrusion function compared to inferior foam product, so you don't have to worry about the collapse of the use process. An excellent adhesive has a strong viscosity that can ensure it stays firm. High quality backing paper is easy to peel and install and not easy to tear. [Equipped with high-quality practical tools, ensure a convenient installation and insulation effect] We also specially align you with appropriate tool for removing aluminium foil and car trim. Removing tools is more durable than market tools. You can easily put the door down without worrying about leaving scars.

The 4 mm thickness of the unpopulation is better suited for the car door, hood, boot, floor, firewall and other parts of the vehicle. You don't have to worry about the phenomenon, not being able to install, as the thickness is too large, but the vehicle gap is not enough.

Review: Hervorragendes Dämmungsmaterial für Auto-Projekte! Die Qualität ist erstklassig und das Material lässt sich einfach zuschneiden und verarbeiten. Die Dämmwirkung ist spürbar besser geworden - weniger Außengeräusche und bessere Akustik im Fahrzeug. Die Selbstklebeschicht haftet sehr gut. Für professionelle Fahrzeugaufbereitung genau das Richtige. Das Preis-Leistungs-Verhältnis ist ausgezeichnet. Klare Empfehlung! LG von Auto Leder Toczek ° Auto-Leder.de °

## Questions & Answers

**Q: Does it come with installation instructions? 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.
