Flexible enough to wrap pipes, ducts and HVAC returns, and it doubles as an air and moisture barrier. - Size and Coverage – One 4 ft x 10 ft roll covers 40 sq ft and weighs about 40 lb. A good size for a door, a small wall, or a car floor. Need more?

For best results cover the whole surface and seal every seam; MLV blocks airborne sound, not footsteps or vibration. - Easy to Cut, Low Odor, Non-Toxic – Cuts clean with a utility knife or heavy scissors to fit around outlets, beams and pipes. Non-toxic, low odor and will not decompose or off-gas. Hang with cap nails or staples, tape the seams, caulk the edges, then cover with drywall. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01G10EYX6 | | Best Sellers Rank | #9,739 in Musical Instruments ( See Top 100 in Musical Instruments ) #283 in Recording Studio Acoustical Treatments | | Customer Reviews | 3.9 3.9 out of 5 stars (52) | | Date First Available | May 22, 2016 | | Item Weight | 40 pounds | | Item model number | 4' x 10' (40 sf) | | Material Type | Polyvinyl Chloride (PVC) | | Product Dimensions | 120 x 48 x 0.01 inches | | Size | 4' x 10' (40 sf) | ## Product Details - **Material:** Vinyl - **Brand:** Soundsulate - **Item Thickness:** 0.12 Inches - **Recommended Uses For Product:** The product is recommended for soundproofing walls, floors, ceilings, doors, home theaters, automobiles, boats, RVs, machinery, equipment, ductwork, and various sound control applications. - **Product Dimensions:** 120"L x 48"W ## Images ![Mass Loaded Vinyl 1 lb MLV Soundproofing Barrier for Walls, Ceilings and Floors, STC 27 Sound Insulation, 1/8 in Thick, Made in USA, 4' x 10' Roll (Covers 40 sf) - Image 1](https://m.media-amazon.com/images/I/51wjhKzPvgL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this stop noise from my neighbors?** A: Yes, for airborne noise like voices, TV and music. Cover the entire wall with no gaps, tape every seam and caulk the edges. Even a small opening lets sound through. **Q: Will it stop footsteps from upstairs?** A: Not by itself. Footsteps are impact noise that travels through the structure. MLV works best alongside decoupling (resilient channel or clips) and insulation. **Q: How much do I need?** A: Multiply the wall's width by its height in feet, then add about 10% for trimming. Example: a 12 ft x 8 ft wall is 96 sq ft, so one 4' x 25' roll (100 sq ft). **Q: How do I install it?** A: Hang it on the studs with cap nails or staples, butt the seams tight, tape them, caulk around the edges, then cover with drywall. At 1 lb per sq ft it's heavy, so use two people. **Q: Is it fire rated?** A: The FSK Reinforced roll is fire rated to ASTM E84. If your project or building code calls for a fire-rated barrier, choose the FSK Reinforced roll. ## Frequently Bought Together - Soundsulate™ 1 lb Mass Loaded Vinyl MLV, Soundproofing Barrier 4 x 10' (40 sf) - Made in USA - Click for Options - UberQuiet MLV Cap Nails, 1-inch, for Installation of Mass-Loaded Vinyl Noise Barriers, Small (250 pcs) - Premium Quality MLV Seam Tape, Installation Tape for Mass-Loaded Vinyl Noise Barriers 6 Mil - Highly Effective Soundproofing Solution - 1.5" x 108 (1) --- ## 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/49567961-mass-loaded-vinyl-1-lb-mlv-soundproofing-barrier-for-walls](https://www.desertcart.co.za/products/49567961-mass-loaded-vinyl-1-lb-mlv-soundproofing-barrier-for-walls) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-12*
