What Is Acoustic Laminated Glass?
Acoustic laminated glass, a type of PVB laminated glass, greatly enhances sound insulation. It utilizes a specialized acoustic PVB interlayer situated between the glass panes. Compared to regular laminated glass, the acoustic PVB layer significantly improves sound control.
To measure sound reduction, the glass’s sound control rating is expressed in decibels (dB) through a weighted sound reduction index (Rw). Typically, traditional polyvinyl butyral (PVB) interlayers receive a rating of 33 dB with a single normal strength (NS) vinyl interlayer.
However, by incorporating a high penetration resistance (HPR) interlayer, the rating can be increased to 34 dB. In particular, when SDG acoustic laminated glass is paired with a 0.76 mm HPR interlayer, it achieves an impressive rating of 38 dB, delivering remarkable sound reduction capabilities.
What’s more, acoustic laminates outperform traditional PVB interlayers in colder temperatures, maintaining their sound-reducing properties. Besides their improved sound reduction index, acoustic laminates also excel in damping sound across the coincidence dip, a frequency range where a glass of a particular thickness normally becomes more transparent to sound waves.

Glass thickness plays a crucial role in determining the level of soundproofing. This applies to all types of glass, including monolithic, laminated, and insulated glass. The thicker the glass, the greater the sound transmission loss.
Enhance the acoustic performance through optimal glass combined options.
If a powerful sound reduction is required, we recommend choosing DGU Laminated Glass for your project. The right spacer thickness is crucial for achieving optimal sound control in insulated glass. Thickner spacers can significantly improve the Sound Transmission Class (STC) rating.
In addition to its role in protecting glass coatings and enhancing thermal insulation, the use of argon gas in insulated glass can further reduce STC. As an inert gas, argon has lower sound conductivity compared to regular air-filled insulated glass.
Benefits Of Acoustic Laminated Glass
- Noticeable improvement in sound reduction
- Works better at lower temperatures
- Superior dampening across the coincidence dip
- SABS approved
They can also be combined with other Shenzhen Dragon Glass products for a multi-functional noise-reduction monolithic glass or a multi-functional noise-reduction insulating glass unit, providing additional benefits such as thermal insulation, solar control, etc.
