EVA Mass Loaded Vinyl (EVA MLV)
EVA (Ethylene-Vinyl Acetate) MLV is a flexible, high-density sound barrier that — unlike PVC MLV — is low-odor, low-VOC, and plasticizer-free. It delivers comparable noise blocking with cleaner handling and reduced off-gassing. Install on walls, ceilings, floors, or as mechanical wraps for residential, industrial, and vehicular projects.
- High-Density Noise Barrier: Dense EVA sheet blocks airborne sound and boosts TL / STC in walls, ceilings, floors, doors, and mechanical wraps.
- Cleaner Than Standard MLV: PVC-free, plasticizer-free EVA means low odor and low VOCs — better for handling and occupant comfort than standard MLV.
- Versatile & Contractor-Ready: Flexible rolls (48-54" wide) cut easily. Fasten with screws and washers — fully compatible with RC / hat-channel decoupled assemblies.
- Vehicle-Ready Fit: EVA holds stability across a wide automotive temperature range, resisting cracking, warping, and moisture down to -20°F for long-term performance.
- Tested & Documented: Fire/smoke and acoustic data (ASTM E84, assembly TL/STC) available for submittals and specifications.
Online orders up to 500 rolls. For anything larger, call (415) 864-4440 and we'll price the project with you.
Freight shipments include a $100 freight-and-handling charge.

EVA MLV Project Calculator
Enter your surface square footage — we'll return the number of MLV rolls (each roll covers 100 sq ft) and the Vinyl Seam Tape rolls needed to seal every butt seam (1 seam-tape roll per 3 MLV rolls).
EVA MLV is priced and installed by the 4' × 25' (100 sq ft) roll. Add ~12% waste for cuts, curves, and seams — vinyl seam tape is required at every butt seam.
STC Gauge
Compare how the EVA MLV performs across assembly tiers. Select an assembly below to see the resulting STC score.
Single ½" drywall each side, no insulation.
- STC 30-39: Loud speech clearly audible next room.
- STC 40-49: Loud speech muffled — normal residential wall.
- STC 50-59: Loud speech barely audible; suitable for offices & multi-family.
- STC 60+: Approaches studio-grade isolation.
How EVA MLV compares
| Model | Type | Flexibility | Typical Use | Notes |
|---|---|---|---|---|
| EVA MLVthis | Mass barrier (EVA polymer) | High | Vehicles, floors, doors, partitions | Dense, moisture-resistant, all-climate — low VOC |
| PVC MLV | Mass barrier (PVC + plasticizers) | Medium | Walls / ceilings | Heavier for the same thickness |
| Butyl CLD | Damping tile | Rigid tile | Metal resonance control | Use sparingly — not a barrier |
| Closed-Cell Foam | Decoupler | Soft | Under MLV | Improves isolation — not a sound barrier |
