## Description

AggSound Car Sound Insulation Mat 394mil 6sqft

Review: In principe goede matten maar er zijn kwalitatief betere merken. Het merk dat ik in het verleden had gekocht is helaas niet meer beschikbaar op desertcart. Na zoeken deze besteld. De set komt met aluminium isolatietape maar helaas plakt dat slecht en zit er papier onder wat je er eerst af moet halen. Uberhaupt niet nodig voor deze isolatiematten. De matten zelf zijn voorgesneden, tenminste, kleiner gemaakt om in de doos te passen want ze zijn alles behalve recht afgesneden. Gelukkig zit er op het papier wel een print met 1cm×1cm ruitjes zodat je het alsnog recht kan knippen, al levert dit wel een hoop ongeruikte kleine stukjes op wat jammer is. De matten plakken wel goed en ben tevreden over de thermische isolatie die ze bieden.
Review: Damit habe ich den Getriebetunnel und die Heckklappe meines 4x4 isoliert. Das Material ist leicht zu verarbeiten. Es kann exakt und einfach mit einer Schere zugeschnitten werden. Der Kleber ist sehr stark, einmal aufklebt - keine Chance auf Korrektur. Man sollte also die zugeschnittenen Teile vor dem Abziehen des Papiers vorher testweise anprobieren. Optisch macht das Material eine sehr guten Eindruck. Wenn ich wieder so ein Projekt vorhabe, würde ich mich für dieses Produkt entscheiden.

## 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.
