I split it down the middle and used a piece for each rear strut tower and wheel well. I did not glue it to the car I glued quality magnets to the rubber side. It's plenty flexible and this keeps moisture from damaging the car and of course can be pulled right off for inspection. The rear seat holds the rest in place. Amazing how quiet it is to have a conversation with someone in the back seat doing 70 down the highway. Yikes.... if more people understood this it would put the luxury car market in serious jeopardy. Anyway, this was my particular use for it and I am impressed. Also thanks for not shorting the length. I think it was even over by half an inch. Rare these days to get anything that is honest. Review: Window Plug for road noise - I bought this to make a window plug for my bedroom window. My neighbor has been terrorizing the neighborhood for months with his HEMI engine at all hours, and this is my last ditch effort to try and get a full night's sleep. I had tried butyl on posterboard first, but it was a major failure. The butyl was way too heavy and didn't provide the sound dampening I needed or expected. Ended up being a complete waste of money. Not something I would recommend for anyone trying to build a window plug, unless you're using wood (not cardboard) and are prepared for a heavy lifting session every time you put the plug in the window. This acoustic foam ended up doing the job way better and makes a much lighter weight plug. I took the extra step of sealing off the edges of the window with gaffer tape, and between that and the foam plug I haven't been awakened by street noise. I used the recommended 3M mounting tape to install the foam vertically onto posterboard the height of the window (36"). I positioned the product as such that foam protrudes from either edge, to make up for the fact that the window is 51" wide but the posterboard is only 48" wide. I had to trim the foam a little bit, and use the scraps to fill up any gaps or cracks when I lift the plug into the window each night. My bedroom is almost completely light tight and so far I haven't been awakened by the demon car since using this setup.🤞🏻 I'm giving 4 stars because it isn't perfect, but it's close. I'll update if anything changes. UPDATE: It's been a few weeks and this stuff has completely changed my sleep. I am no longer awakened at all by street noise or the demon car! Increasing to 5 stars because it did what I bought it to do. ## Features - 【SPECIFICATION】: Size: 39.4''L X 13.4''W X 0.3''H; Covering 3.66 square feet; Weight: 2.75 lbs; Material: multi-layer space cotton & sturdy rubber soundproof blanket for exceptional vibration dampening.

How bad is he smell what are all of the sizes** A: No you will want to find something else. This will not work for sewing this onto anything. Putting on a wall or back of a door is fine. **Q: Has anybody used it to wrap pvc water pipes to reduce the dounds** A: Tried to cover pipe in wall but too thick to fit and cover with dry wall. **Q: Can i use this in a hvac room that gets warm because of the heat or do i have to worry about it bursting into flames?** A: My experience using wrapping a noisy refrigerator compressor tightly did not result in flames. Rather than replace the unit the Comp. which seemed noisy probably got a bit hotter. Still intact 3 years later **Q: I'm buying this to soundproof a window. What side should I put closest to the window itself - the eggshell or the flat surface?** A: If you want to reduce the sound transmission coming into the room, put the "eggshell" toward the window. If you want to reduce the sound transmitted through the window to the outside, put the "eggshell" toward the interior of the room. Keep in mind, this will help reduce some mid to high range sound, but lower range sounds will not be affected noticeably. So, it won't "soundproof" a window, but it should reduce things like street noise. ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality... *by T***N on December 26, 2025* This stuff is high quality and worked way better than I thought it would.

I put me cellphone in a box with music playing and wrapped it in this foam. Barely made any difference. The foam is just thin egg carton foam used for mattress covers. Not dense enough to do anything. Rubber backing is good quality but overall, not fit for purpose. ## Frequently Bought Together - BXI Double Noise Blocker Sound Proof Foam, 39.4 X 13.4 X 1 Inch Egg Crate Foam Rubber Sound Deadening Material, Dampening Acoustic Foams Panels for HVAC, Pipe, Machine, Window, Wall, Door - BXI Soundproofing Closed Cell Foam - 2 Pack Self-Adhesive 16'' X 12'' X 1.8'' Thickened Egg Crate Sound Proof Foam - Acoustic Foam Panels Great for Noise & Thermal Insulation (Black) - Kaqiluo 2 Pack High Density Self-Adhesive Sound Insulation Acoustic Closed Cell Foam, 0.4" x 12" x 71", 10 mm Thick,11.6 sqft Sound Proof Padding,Fire,Water Resistant Acoustic Treatment Foam --- ## 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.co.za/products/323598730-bxi-high-density-rubber-backed-sound-proof-foam-39-4](https://www.desertcart.co.za/products/323598730-bxi-high-density-rubber-backed-sound-proof-foam-39-4) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-14*
