There are many trade names for MLV, and all are simple PVC sheet, loaded with Barium Sulfate or gypsum powder to add weight. Mass Loaded Vinyl is very dense, weighing one pound per square foot. This mass is what allows the MLV to be effective at reducing airborne noise.
We do not recommend the use of MLV in walls, floors and ceilings. Years ago, before new technology, MLV was a standard in sound isolation designs. Today there are lower cost, higher performance materials that are recommended for walls and ceilings, such as Green Glue or Sound Isolation Clips. MLV still has utility in wrapping curved surfaces and adding mass to pipes, ducts and steel framing members.
Features:
- High tear and tensile strength
- Reduce noise transmission
- Limp, flexible, formable and versatile
Applications:
Mass Loaded Vinyl can be used as a barrier material to wrap metal ducts, plastic plumbing pipe, steel columns, etc. |
