Plenum (Class A) 1.0 lb. Non-Reinforced

  • Reduces Sound Transmission
  • Contains Noise
  • Improves Communications
  • Improves Health & Safety

Mass Loaded Vinyl is a dense and heavy material that effectively blocks sound transmission. MLV curtains can be used to create a sound barrier in spaces where noise needs to be controlled, such as recording studios, home theaters, or noisy industrial environments.

Mass Loaded Vinyl (MLV) curtains are a type of acoustic treatment used to improve soundproofing and reduce noise in various settings. These curtains are designed with Mass Loaded Vinyl material, which is known for its sound blocking properties.

The cost of MLV curtains can vary depending on the size, thickness, and additional features. While they may be more expensive than regular curtains, they provide significant soundproofing benefits.
