It blocks 98% of radiant heat, is fully waterproof and oil-resistant, and features a self-adhesive backing for easy installation. Covering 18 sq ft per roll, it offers durable, lightweight, and cost-effective thermal and vibration protection, ideal for doors, floors, roofs, and engine compartments. ## Description Siless Aluminum Foil Finish Liner is a high density, closed cell foam with aluminum finish that serves as an efficient heat and vibration absorber. Closed-cell foam is an effective material for reducing noise reverberations, and the Siless Liner is moisture-resistant, fire-retardant, and dust-free. Our heat-blocking foam rolls are pliable and easy to work with, and they install in minutes. The high-density closed-cell foam is perfect for firewall, doors, roof, trunk and floor. Siless Liner is the most effective automotive thermal insulator available online, and perfect to use on top of Siless Sound Deadening Mat. It is a soft, self-adhesive closed cell foam with many thousands of cells packed extremely close together, which gives the material near zero air infiltration. This is the key to its ability to reduce heat, as well as resist oil and water. Since it will not hold water, it will not promote rust like most under carpet padding and thermal insulators. Siless Liner is also durable enough to be crush and tear resistant. Because of its durability and ability to resist oil and water, Siless Liner is long lasting. Siless Liner has the highest heat blocking properties available in a single layer synthetic foam. Combined with Siless Sound Deadening Mat, its nearly doubles the total thermal resistance ability. It provides excellent insulation for the roof, firewall, floor, quarter panels, doors, and even under the hood. Review: Great - Good product. Sound proofing.

Sound proofing. ### ⭐⭐⭐⭐⭐ Great *by S***H on August 11, 2025* Used for a heat/light/noise insulation. Worked great. Easy to install. ### ⭐⭐⭐⭐ Pretty good quality at a OK price! *by S***A on September 6, 2025* I will say that the aluminum lining was kind of thin and the insulating foam kind of cheap also it was in a roll and not the square panels, which was helpful and not all the same time! As I was doing a no perfectly square object. But I will say that the insulating factor is pretty good the use was fantastic. The quality for the price was fair. There wasn't any significant odor from the material and it is keeping great temperature for my insulated enclosure! The adhesive sticks very well, but not so well that you can't make adjustments if you need to! --- ## 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.tn/products/666469929-siless-liner-157-mil-18-sqft-aluminum-foil-finish-car](https://www.desertcart.tn/products/666469929-siless-liner-157-mil-18-sqft-aluminum-foil-finish-car) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-22*
