The primary difference between regular laminated glass and acoustic laminated glass is acoustic performance. Regular laminated glass is focused on safety and impact resistance, whereas acoustic laminated glass is designed to provide better sound isolation while retaining the safety benefits.
Key Differences:
- Acoustic Performance: Acoustic laminated glass offers superior noise reduction compared to regular laminated glass, especially in the suppression of high-frequency sounds.
- PVB Interlayer Material: Acoustic laminated glass uses specially designed acoustic PVB interlayers, which have higher density and more complex structures to improve sound isolation.
- Price: Acoustic laminated glass is more expensive than regular laminated glass due to the use of specialized acoustic PVB interlayers and additional manufacturing complexity.
- Applications: Regular laminated glass is mainly used for safety purposes, while acoustic laminated glass is used where noise control is critical, such as in environments with high noise exposure.
