Review: Cost effective - 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.
Review: Cheap and worked for what I needed. - I bought this on a whim to go with some Kilmat sound deadener. It is not thick, but definitely made the truck even quieter. The Kilmat takes out the vibrations and resonating noise, the foam takes out the echo you might say.

## Features

- 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.

- 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.

### ⭐⭐⭐⭐ Great product…worth every penny
*by T***Y on July 30, 2025*

Used this in a speaker box build and it definetly worked well, significant difference in vibration. Very much worth the money. Only downside I could see is with how sticky the material is, the foam likes to stay stuck to whatever it touches which in reality is a good thing. Tried cutting with a utility knife but maybe there’s a better tool that would have made it easier to cut
