1. Blocks Sound Transmission
Partitions (like drywall or gypsum walls) are usually lightweight, so sound can easily pass through them.
MLV adds mass, which is the most important factor in stopping sound.
👉 More mass = Less sound passing through
2. Improves STC Rating
MLV significantly increases the Sound Transmission Class (STC) of a partition.
- Without MLV → Sound leaks easily
- With MLV → Noise reduction improves by 5–10+ STC points
This means better privacy and less disturbance between rooms.
3. Flexible & Easy to Integrate
MLV is flexible, so it can be installed:
- Inside drywall partitions
- Behind gypsum boards
- Between two wall layers
It doesn’t require major structural changes.
4. Works on All Frequencies
Unlike foam or panels (which absorb mainly mid/high frequencies), MLV:
- Blocks low-frequency noise (bass, machinery, traffic)
- Also controls mid and high frequencies
This makes it ideal for complete soundproofing.
5. Prevents Noise Leakage
Even small gaps in partitions allow sound to escape.
MLV acts as a continuous barrier, reducing leakage through:
- Walls
- Joints
- Cavities
6. Ideal for Both Residential & Commercial Use
MLV is widely used in:
- Office partitions (privacy)
- Meeting rooms
- Home theaters
- Hotels & hospitals
- Industrial enclosures
Simple Understanding
- Partition alone = ❌ weak sound barrier
- Partition + MLV = ✅ strong soundproof wall
Pro Tip (Very Important)
For best results:
- Use MLV inside the partition (to block sound)
- Add Acoustic PET Panels outside (to absorb echo)
👉 This gives you complete acoustic control (blocking + absorption)
“Upgrade your partitions with MLV for superior soundproofing, enhanced privacy, and complete noise control.”
