## 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: Is this heat resistant? Is this material suitable for insulating the firewall against engine heat?**
A: Yes, our 394mil Aluminum Foil insulation is perfect for firewall and engine bay use. Its multi-layer design provides excellent heat resistance, effectively blocking heat. For best results, ensure full coverage and seal edges with aluminum foil tape.

**Q: How thick should sound deadening mats be?**
A: Butyl: 2-3mm (80-120 mil) for vibration damping Closed-cell foam: 4-6mm (157 mil) for noise blocking Aluminum composites: 8-10mm (315-394 mil) for thermal insulation Thicker isn't always better - proper installation and coverage matter more.

**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.
