You DON'T need a roller to apply this, just strong hands and a well prepped surface. I vacuumed, lightly washed, then used 90% alcohol to clean the surface before applying. I could have used more and covered every inch, but there is diminishing returns in doing so (especially on a budget, or with a lower wattage sound system in my opinion). If this stuck as well as it did for me in a 45° garage, then it should stick just fine for you too. I will say, it is a little cheap feeling, but for the price I can't complain. There is an audible difference when knocking on the panels this material is applied to. I'm not a professional though, and if you're an audiophile, there are better options (but prepare to empty your wallet). Not sure I would do an entire vehicle with this material, but it is a great supplement. Review: Metal sink no longer as loud - We have a metal utility sink in our pantry/laundry room which I use to clean pots and pans. The noise was so loud I knew I needed to do something. I discovered these stick on sound deadening mats and I put them on the sides, back and bottom of the sink. They have reduced the sound quite a bit, it doesn’t bother us so much when we’re cleaning. It was easy to install and made such a difference. ## Features - Choose the Coverage That Fits Your Project: Includes 8pcs/8.7 sqft total coverage area (each 9.8" × 15.7", 197mil / 5mm thickness)—easy to plan coverage and start small upgrades. Need a different thickness or coverage area? Choose from 4mm / 5mm / 10mm thickness, with coverage options of 1 roll/19 sq ft, 2 roll/38 sq ft, 12pcs/13.1 sq ft, 15pcs/16.3 sq ft, or 34pcs/37.1 sqft—pick the right sound deadening mat for your build. - Quieter Drive, Less Rattle & Vibration:Dense closed-cell foam supports sound deadening by reducing road noise, panel vibration, and interior rattles for a more comfortable ride. Noise levels can drop from ~52 dB to ~29 dB (about 50% lower). It also helps with sound dampening by absorbing both high- and low-frequency noise to keep your cabin quieter. - Heat-Reflective Foil Helps Reduce Heat Soak:Foil facing helps reflect radiant heat from the engine/exhaust and summer sun, supporting car insulation and improving comfort. The aluminum layer can reflect up to 95% radiant heat (lab), helping reduce heat transfer when applied to areas like hood/firewall/roof. - 4-Layer Build for Reliable, All-Weather Use:A foil + foam + PSA adhesive + release liner construction built for real car use. The waterproof foil surface wipes clean easily and resists everyday wear. Working temperature range: -40°F to 300°F. A dependable sound deadening material for cars built for both hot and cold conditions - Peel & Stick Install — Easy to Cut & Apply:Strong PSA self-adhesive backing helps it stay put once pressed firmly in place. Easy to measure, trim, and fit around curves and corners with scissors or a utility knife. Apply this sound deadener to doors, floor, trunk, wheel wells, roof, hood, firewall, cargo area and more. The waterproof adhesive helps provide a lasting hold. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B6181QSK | | Best Sellers Rank | #6,750 in Automotive ( See Top 100 in Automotive ) #12 in Automobile Insulation | | Brand | KOIKEY | | Brand Name | KOIKEY | | Coverage | 8.7 square foot | | Customer Reviews | 4.5 out of 5 stars 1,513 Reviews | | Item Dimensions L x W | 15.7"L x 9.8"W | | Item Highlight | Aluminum foil heat shield, Foam material, sound dampening and heat insulation for doors, trunks, floors and vehicle interiors | | Item Thickness | Aluminum 197 mils | | Manufacturer | KOIKEY | | Manufacturer Part Number | CIP5M8P | | Model Number | sound deadening | | Number of Items | 8 | | Product Dimensions | 15.7"L x 9.8"W | | Recommended Uses For Product | sound insulation, vibration dampening, heat insulation for vehicles | | UPC | 703729826523 703729826530 | | Unit Count | 8 Count | ## Product Details - **Brand:** KOIKEY - **Item Thickness:** Aluminum 197 mils - **Manufacturer:** KOIKEY - **Product Dimensions:** 15.7"L x 9.8"W - **Recommended Uses For Product:** sound insulation, vibration dampening, heat insulation for vehicles ## Images ![Car Sound Deadening Mat, 197 Mil 8.7 sqft Sound Deadener - Image 1](https://m.media-amazon.com/images/I/61mkgv0YToL.jpg) ## Available Options This product comes in different **Item Thickness String, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good value and sticks well *by C***S on March 15, 2026* For $14 for 8.7 square feet, this was more than enough to cover the important parts of the trunk of my 944.

The noise was so loud I knew I needed to do something. I discovered these stick on sound deadening mats and I put them on the sides, back and bottom of the sink. They have reduced the sound quite a bit, it doesn’t bother us so much when we’re cleaning. It was easy to install and made such a difference. ### ⭐⭐⭐⭐⭐ Cost effective *by J***K on June 7, 2026* Nice, cost effective material. It stuck nicely to the door and was fairly easy to use. The grid marks on the back made it easy to cut. I would not rank it up with other materials in sound and heat isolation, but it did cut down the overall vibrations on the door panels and I did not feel heat immediately from the floor area as i did with bare metal. If you are working with a budget and want modest improvement, this material will work well over most stock materials. ## Frequently Bought Together - Car Sound Deadening Material Mat - 197 mil 8.7 sqft Auto Audio Deadener Foam, Sound Dampening and Heat Insulation for Truck, Vehicle - APIELE 16mm Latching Push Button Switch 12V DC On Off Black Shell with LED Angel Eye Head for 0.63" Mounting Hole with Wire Socket Plug Self-Locking (Blue/Black Shell) - ARRAROWN ZK-1002T 2.0 Channel Bluetooth 5.0 Amplifier Board 200W HiFi Subwoofer Audio AMP with Treble and Bass Control BT and AUX Inputs, DC 12-24V 2.0 Channel Stereo AMP Module for DIY Speakers --- ## 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/451382218-car-sound-deadening-mat-197-mil-8-7-sqft-sound](https://www.desertcart.tn/products/451382218-car-sound-deadening-mat-197-mil-8-7-sqft-sound) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-30*
