Q: Does it come with installation instructions? What's the best way to install it for maximum results?

1.Remove & Clean: Take off interior panels; clean and dry surfaces

Q: What's the difference between Aluminum Foil and Closed-cell Foam?What are the best sound deadening solutions for sound?

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 sound deadening materials work to reduce noise? Can it reduce road noise? Can it be used on car doors?

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?

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.
