Yaojing Acoustic PVB Film is engineered to deliver superior sound insulation performance in laminated glass systems. With a standard thickness of 0.76 mm, this high-performance acoustic interlayer is trusted by architects, façade engineers, and glass processors across China, the UAE, and the entire GCC region for noise-sensitive projects.
🔇 What Is Acoustic PVB?
Acoustic PVB (polyvinyl butyral) is a specialized interlayer used in acoustic laminated glass. Unlike standard clear PVB, which is designed primarily for safety and UV protection, acoustic PVB is formulated with soft plasticizers and damping additives to absorb and reduce sound transmission.
This makes it ideal for soundproof glass installations in:
-
Residential buildings near highways or airports
-
Offices, hotels, and hospitals
-
Recording studios and broadcasting centers
-
High-end automotive glazing
⚙️ Materials Used in Yaojing Acoustic PVB
Yaojing Acoustic PVB is made from:
-
High-quality PVB resin
-
Specialized acoustic plasticizers (like TEGDMEH or DOA)
-
Optional co-extruded damping layers
-
UV stabilizers and optical clarity agents
These components give the interlayer its elastic damping properties, allowing it to disrupt sound waves and significantly reduce noise levels compared to standard PVB.
📊 Acoustic Performance by Glass Thickness
| Glass Configuration (Laminated) | Approx. Sound Reduction (Rw) | Use Case |
|---|---|---|
| 4 mm + 4 mm | 38–39 dB | Residential or internal partitions |
| 5 mm + 5 mm | 40–41 dB | Mid-range acoustic glass |
| 6 mm + 6 mm | 43–45 dB | Standard soundproof windows |
| 8 mm + 8 mm | 46–47 dB | Premium sound insulation |
| 10 mm + 10 mm | 47–48 dB | For hospitals, studios |
| 6 mm + 12 mm (asymmetric) | 45–46 dB | Enhanced low-frequency performance |
✅ With 6 mm + 6 mm glass, Yaojing Acoustic PVB achieves up to Rw 45 dB in standard lab conditions (ISO 10140 or ASTM E90).

🧪 How It Works
Sound travels through air and solid materials as pressure waves. When those waves hit a laminated glass structure with acoustic PVB, the interlayer deforms microscopically and dissipates the sound energy as heat due to its elastic and damping properties.
In contrast, standard PVB lacks the damping characteristics to absorb much sound energy—it simply transmits more of the vibration through the glass.
