2 LB Mass Loaded Vinyl | 4' x 4' Soundproofing Roll

EnviroFlex™ Mass Loaded Vinyl is a premium, high-performance soundproofing solution designed for homeowners, contractors, and commercial builders who need maximum noise control. Made from dense, flexible recycled vinyl, this acoustic barrier blocks sound transmission through walls, ceilings, floors, and vehicles, delivering reliable results without bulky materials. Whether you’re tackling a DIY soundproofing project or managing a large-scale commercial installation, EnviroFlex MLV offers the ideal balance of performance, durability, and sustainability.

With a high STC (Sound Transmission Class) rating, EnviroFlex™ effectively reduces airborne noise such as voices, music, machinery, and traffic. Its flexible composition makes it easy to cut, shape, and install, whether applied directly to studs, layered behind drywall, or combined with insulation for superior results. Unlike spray foams or fiberglass alone, MLV creates a continuous, dense barrier that stops sound at the source.

EnviroFlex™ MLV is available in both 1 LB and 2 LB per square foot options, giving you the ability to match weight and performance to your specific application. Typical uses include residential remodeling, commercial office construction, music studios, home theaters, industrial spaces, and even vehicle and van soundproofing. Backed by our commitment to eco-friendly manufacturing, EnviroFlex is crafted from 100% recycled materials, making it not only effective but also a sustainable choice for modern construction.

If you’re looking for soundproofing that works, EnviroFlex™ Mass Loaded Vinyl delivers proven acoustic control with professional-grade quality. Reduce noise, improve comfort, and build quieter spaces with confidence.
