Acoustic Glass

Acoustic laminated glass is a premium product featuring a PVB (polyvinyl butyral) acoustic interlayer designed to significantly reduce noise. It works by reflecting and absorbing sound waves, effectively limiting the transmission of sound frequencies between the glass panes and dramatically minimizing noise intrusion.

Compared to standard laminated glass of the same composition, acoustic laminated glass provides superior sound reduction, thanks to the enhanced properties of the acoustic PVB interlayer.

This type of glass is ideal for reducing environmental noise from sources such as ground and air traffic, school playgrounds, industrial areas, and places like bars or factories.

The level of acoustic performance can be customized by adjusting the thickness of the glass and the acoustic PVB interlayer. With a wide range of product options, acoustic laminated glass can meet specific noise reduction requirements for diverse environments.

Comfort, Safety
& Noise Reduction

Rw represents the weighted sound reduction index, measured in decibels, which includes a correction factor to account for human hearing sensitivity. C and Ctr are spectrum adjustments, values added to Rw to account for the specific characteristics of different sound frequencies.

An acoustic Insulated Glazed Unit (IGU) combines all the advantages of laminated glass—such as safety, security, and UV protection—without sacrificing light transmittance. This ensures that you enjoy optimal comfort and protection in your home, while also significantly reducing unwanted noise.

Windows and glazing play a crucial role in noise reduction, and acoustic glass can be further enhanced by integrating other functionalities such as solar control, thermal insulation, and self-cleaning properties.
