Acoustic glass partitions

One or more acoustic interlayers and one or more layers of polyvinyl butyral (PVB) are used to bind two or more sheets of glass together, producing acoustic glass. The high-frequency sound waves are prevented from entering by the membrane’s ability to absorb them and prevent their transmission through the glass.

In most cases, acoustic-grade glass outperforms double glazing regarding sound absorption since it is constructed from multiple layers of glass laminated with acoustic foam or laminate. This space between the panes and the laminate prevents sound from passing through the window, while double glazing often consists of only two layers of glass, making it more difficult for sound to flow through. This gap helps to prevent sound from passing through the window.

The typical thickness of glass walls is between 10.8 and 12.8 millimetres in household windows. You can purchase acoustic glass with a thickness of up to 20.8 millimetres; however, at this level of thickness, the glass becomes very heavy, which makes it challenging to support conventional window designs. Thicker acoustic glass partition walls may be used for business purposes, such as interior dividers, recording studios, and conference rooms. A weighted sound reduction index of 42 decibels is achieved by glazing with a thickness of 20.8 millimetres.

An acoustic glass panel is the industry standard for preventing unwanted noise from seeping into a residence. Waves of sound travel in a similar fashion to waves of water, with higher strength resulting in louder and longer waves. By absorbing the sound wave’s energy, the soundproof membrane within the glass prevents vibrations from flowing through the glass.
