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.
