I purchased the Siless as the most economical choice. I would like to be able to compare products as to their damping performance specifications, (not available) but a choice for the lighter weight material was a plus.I used 108 sq ft of Siless and saved 30 extra lbs weight that wouldn't have helped my electric vehicle's battery range. I also added a 157 ml layer of their sound matt overtop. I own a very quiet ride! **Q: Will this help reduce engine noise in a diy generator box made of plywood? (to inside walls away from exhaust)** A: Thank you for your question. You would get much better results installing butyl based material on metal. With plywood, it won't help you much. **Q: Can this be used a a heat sheild for a Wood stove** A: Thank you for your question. Siless 80 mil sound deadening mat is not recommended to be used as a heat shield for wood stove. **Q: Could you use this to keep music room noise from bothering neighbors? Specifically, could you put it on a wall?** A: You could put it on walls. But as for suppressing noise from a neighbor, I don't think so. It's best to use acoustical tile for rooms. ## Frequently Bought Together - Siless 80 mil (2mm) 36 sqft (3.4 sqm) Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material (36 sqft) - Car Sound Deadening Roller Metal Installation Tool 3 Pcs for Auto Noise Roller Car Sound Deadener Application Installation Tool Rolling Wheel Interior Accessories - Siless Liner 157 (4 mm) mil 36 sqft Car Sound Deadening Closed Cell Foam & Heat Insulation mat - PE Foam Sound Deadener Material & Heat Barrier --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/255814939-siless-80-mil-36-sqft-sound-deadening-mat-sound-deadener](https://www.desertcart.jp/products/255814939-siless-80-mil-36-sqft-sound-deadening-mat-sound-deadener) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-12*
