Thinner options work well for door panels, while thicker ones are designed for areas needing more material, such as vehicle floors or the firewall. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BNBTD2NZ | | Best Sellers Rank | #105,472 in Car & Motorbike ( See Top 100 in Car & Motorbike ) #130 in Automobile Insulation | | Brand | AggSound | | Brand Name | AggSound | | Coverage | 18 square feet | | Customer Reviews | 4.3 out of 5 stars 73 Reviews | | Included Components | car sound insulation, car trim removal tool, noise barrier finishing tape | | Item Dimensions L x W | 4.2L x 0.4W Meters | | Item Thickness | 157 Mils | | Manufacturer | AggSound | | Material | Aluminum Foil & Closed Cell Foam | | Material Type | Aluminum Foil & Closed Cell Foam | | Product Dimensions | 4.2L x 0.4W Meters | | Recommended Uses For Product | Sound Insulation, Heat Insulation | | Unit Count | 18.08 Square Feet | ## Product Details - **Material:** Aluminum Foil & Closed Cell Foam - **Brand:** AggSound - **Item Thickness:** 157 Mils - **Manufacturer:** AggSound ## Images ![Sound Deading Material for Cars, 157mil Aluminum Foil Foam Mat - Image 1](https://m.media-amazon.com/images/I/71JrWMt9ftL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐ Very lightweight *by S***N on 10 August 2024* ### ⭐⭐⭐⭐ Work good. *by C***R on 16 October 2024* ### ⭐⭐⭐⭐⭐ Sound deadner *by J***R on 24 January 2024* ## Frequently Bought Together - AggSound Car Insulation A 157mil 18sqft - Xtozon Car Sound Deadener Noise Filter Application Rolling Wheel --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/682297352-sound-deading-material-for-cars-157mil-aluminum-foil-foam-mat](https://www.desertcart.us/products/682297352-sound-deading-material-for-cars-157mil-aluminum-foil-foam-mat) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-16*
