Covering 36 sqft per roll, it offers premium thermal protection and vibration dampening at a fraction of the cost of similar products. ## 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: Shrunk after directly sunlight exposure - This product does not perform.

For floor and roof installation, we always recommend Siless 80 mil first and then Siless Liner 157 mil on the top of it. **Q: Will this work on the underside of the car as a heat barrier/shield from the exhaust** A: I think the foam would melt or burn and get too hot if it was real close to the exhaust pipe underneath the car. probably wouldnt stick well to the dirty underside anyway. However, if you apply it on the inside of car body above the exhaust area you will lessen the flow of heat (and noise) into the interior. You can also apply several layers to increase the R value. **Q: Would this work goodon my van walls** A: Thank you for your question. Yes, it will be good for your van walls. **Q: What is the thickness of the foam? Could it be cut into a one or two inch strip and wrapped around a 3" tube? Does it scratch easily?** A: It is 157 Mil 37.5 Sqft. Yes, you could cut it into one or two inch strips. It has self adhesive side, and you can install it around a 3" tube. It is not easy to scratch it, but everything depends on the environment where you install it. ## Customer Reviews ### ⭐ Shrunk after directly sunlight exposure *by R***B on 22 August 2022* This product does not perform. It shrunk by around 25pct after exposure to heat and sunlight covering the cars Panoramic Roof. ### ⭐⭐⭐⭐⭐ Very good, heat resistant easy to install *by K***N on 25 July 2026* Great product, easy to cut with scissors and install. Very sticky so make sure where you place it, you want to keep it. Well made and has seem to cut down on the transfer of heat I. My vehicle roof. Size is more than enough, well worth the money. ### ⭐⭐⭐⭐⭐ Easy to install, cheaper and better than other self proclaimed 100% sound proofing products. *by S***H on 27 May 2026* The 2022 Honda Civic Sport has a noticeably "hollow" and loud cabin at highway speeds. Honda skipped premium sound-deadening in this trim to keep the car lightweight and affordable. So, instead of spending a couple of thousand more on the trim, I decided to give Siless Liner a try and I am stunned by the results. The difference is night and day. I am very impressed by the quality of this sound deadening foam liner. it took me about 2 hours to completely cover my car's boot. ## Frequently Bought Together - Siless Liner 157 mil (4 mm) 36 sqft Aluminum Foil Finish Car Sound Deadening & Heat Insulation Closed Cell Foam - PE Foam Sound Deadener - LUMITECO Bearings Equipped Automotive Car Audio Sound Deadening Application Wheel Roller, Heat Abatement Mat Wallpaper Application PU Smoothing Tool Seam Roller - 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) --- ## 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.sn/products/303641766-siless-liner-157-mil-36-sqft-aluminum-foil-finish-car](https://www.desertcart.sn/products/303641766-siless-liner-157-mil-36-sqft-aluminum-foil-finish-car) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-17*
