## Description

AggSound Car Sound Insulation Mat 984mil 6sqft

Review: Bom material
Review: VERY disappointing. The sheet was TIGHTLY rolled, the backing was stretched, and the exposed adhesive stuck to the non-adhesive surface and pulled a stripe of it off when unrolled. Ruined the last 8" of the sheet for any use that requires a good appearance. It's a good quality closed-cell foam, but the vendor rolled it up so tight, it's not likely to ever lay flat again. I doubt the adhesive will hold it flat either, it has such a warp to it. All they'd have to do is roll it looser and put it in a larger box. UPDATE: the adhesive is good and sticky, but the foam is delicate and fragile. Cutting it with shears leaves gooey residue on the shears/scissors. Cutting it with a knife leaves a ragged, uneven cut. Pulling the foam away (from being stuck) leaves an ugly black smear behind. In short, this stuff is difficult to work, doesn't look good, and has to be covered up or protected in some way. Disappointing, and I wouldn't buy it again.

## 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.

*by D***G on 11 October 2024*

Foam seamed okay, but the backing was not the same size as the foam. All the edges of the adhesive were dirty and wouldn't stick properly, or was stuck to the front of the foam when it was rolled up.
