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.

MLV works by adding dense, flexible mass to the wall system. The standalone STC rating matters, but the bigger result comes from how the material performs as part of a complete wall, ceiling, or enclosure assembly.
For this product, STC 26 gives shoppers a simple way to understand the material’s sound-blocking capability before installation.
MLV is most effective when combined with drywall, insulation, sealed seams, and proper mechanical fastening.
Sound travels through weak points. Seal seams, edges, outlets, and penetrations to get the best result from the system.
Important: STC results depend on the full assembly, including framing, insulation, drywall layers, sealed seams, penetrations, and installation quality.
Use as a barrier layer in wall assemblies where added mass helps reduce sound transfer.
Add material above or below ceiling assemblies to support better noise control between spaces.
Cut to fit vans, cars, service vehicles, and other mobile spaces that need added sound control.
Confirm the surface, space, vehicle floor, stair, or installation area before cutting or ordering accessories.
Use a straight edge and sharp utility knife where trimming is needed, or align the product before final placement.
Fasten, tape, drill, adhere, or drop the product into place depending on the product type and application.
Inspect seams, edges, fitment, coverage, and surface contact before putting the area back into service.
