I think your husband might have other ways he can think of that he’d prefer and enjoy more, but it might require you to have a prescription for extra-heavy-duty-strength viagra and/or cialis first. (I’m assuming that would even work for your condition…..) **Q: how many square feet are in the bulk pack** A: There are 9 sheets in the bulk package. Each sheet is 32" x 18" for a total of 36 square feet. **Q: Would Dynamat be good to use on a cargo van metal floor to reduce road noise? Insulation would be next layer before plywood.** A: Yes, especially in passenger area. It would also work in the rear/behind the seats. Not cheap though.I'd use Dynamat Xtreme in passenger area and run of the mill insulation (silver foil on both sides of matting) in the rest of the van. **Q: how would it does a roof headliner would it fall with the extreme heat?** A: Nope, has fallen on me, and actually got the weaker one before this one came out. Been about 3 threes going strong. Will fail with water. ## Frequently Bought Together - Dynamat Extreme Xtreme Bulk Pack Heat & Sound Deadening - DYNAMAT 10007 Dyna-Roller Professional Heavy Duty Sound Deadener Installation Tool with Wood Handle and 2" Wide Rubber Roller – Made in USA - Celsus 10455 Dynamat Xtreme, Black,18" x 32" --- ## 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.jp/products/1893820-extreme-xtreme-bulk-pack-heat-and-sound-deadening](https://www.desertcart.jp/products/1893820-extreme-xtreme-bulk-pack-heat-and-sound-deadening) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-18*
