AudioSeal Mass Loaded Vinyl Soundproofing Barrier is the go-to for sound reduction in walls, ceilings and floors. Unlike traditional MLV products, this product is non-toxic and made without plasticizers or other hazardous chemicals. It’s also 100 percent recyclable and eligible for LEED credits. Contractors respond to this because it is flexible, tear-resistant and easy to cut with a knife. For the best sound reduction, attach directly to studs or joists so the barrier can flex. If you need to retrofit an existing wall, simply hang the barrier with nails across the top stud, adhere it to existing drywall and add another layer of drywall or other finish.
