An In-Depth Look at Acoustic Glass

As a seasoned glazier with over a decade in the glass industry, I bring a wealth of knowledge and experience to this evaluation of acoustic glass, a specialized glass variant designed to minimize noise penetration. Widely implemented in hospitals, schools, and office buildings plagued by noise pollution, this cutting-edge glass product comes with an innovative construction involving a sound-absorbent layer sandwiched between two layers of glass.

The Mechanics of Acoustic Glass

The secret to acoustic glass’ noise mitigation capabilities lies in its unique construction. When sound waves strike this type of glass, the middle layer absorbs the sound energy, transforming it into heat, which is subsequently dissipated. As a result, the sound waves find it harder to traverse the glass, creating a significantly quieter environment on the other side.

Noise Reduction Capacity of Acoustic Glass

The noise reduction efficacy of acoustic glass depends largely on the thickness of the glass and the sound-absorbing material used within the laminate layer. Generally, the thicker the glass and the more effective the sound-absorbing material, the greater the noise reduction.

A case in point is the Viridian Hush Glass, a leading brand in the acoustic glass market. A 6mm variant of this product can block up to 36db of noise, marking a 34% improvement over conventional glass.

Comparative Analysis: Acoustic Glass vs Regular Glass

The standout feature of acoustic glass, which distinguishes it from regular glass, is the sound-absorbent layer encapsulated within two glass layers. This unique design leads to a substantial reduction in noise transmission. On average, an acoustic glass of similar thickness as regular glass offers an approximate 6db, or 50%, reduction in sound transmission.

Investment Consideration: Cost of Acoustic Glass

The price point of acoustic glass hinges on various factors such as the size, thickness, and type of glass chosen. For instance, Vlam Hush, another variant of acoustic glass, is priced at around $440 per square meter.


The effectiveness of acoustic glass compared to double glazing depends on individual needs. Acoustic glass generally surpasses double glazing in terms of noise reduction. However, double glazing usually scores higher on energy efficiency, which may result in lower energy bills.

Hush Glass is a proprietary acoustic glass variant produced by Viridian. Due to its superior quality and noise reduction attributes, it’s one of the most sought-after acoustic glass brands in the market.

Absolutely! Acoustic glass is an excellent option for residential properties located in noisy areas. It significantly reduces noise pollution, leading to a quieter and more comfortable living environment.

The sound reduction level of acoustic glass is measured in decibels (dB). The higher the dB rating, the more noise is reduced.

No, there is no noticeable difference in appearance. Acoustic glass looks just like regular glass. The difference lies in the internal structure, with the sound-absorbing layer hidden between the two layers of glass.

While acoustic glass is primarily designed for noise reduction, it can also offer some level of thermal insulation, particularly if it is double-glazed. However, for optimal thermal insulation, specially designed thermal glass or double glazing is recommended.

What Our Clients Say About Acoustic Glass

To help you understand the tangible benefits of Acoustic Glass, we’ve gathered several testimonials and case studies from our clients who have experienced a substantial improvement in noise reduction after installation:

Case Study: Residential Home in Surry Hills NSW
Lucy Davis, a homeowner in Sydney, opted to install acoustic glass in her home. She commented, “The improvement was instantly evident. Our home has become so much quieter, shielding us from the hustle and bustle of city life. The noise reduction was so significant that it felt like moving to a quiet suburb. I’d wholeheartedly recommend Acoustic Glass to anyone looking to escape from noise pollution.”

Case Study: Optus Centre, 1 Lyonpark rd, Macquarie Park NSW
Stewart Burns was responsible for the implementation of acoustic glass in an office building. He noted, “We’ve observed a remarkable enhancement in our employees’ working conditions. The acoustic glass drastically reduced external noise, facilitating a more focused and productive work environment. I can confidently say that it was a beneficial step towards improving our workspace.”

Case Study: Culture Kings, Parramatta NSW

Patricia Gomez, a retail store manager, recounted her experience: “After installing acoustic glass, we noticed that our customers could shop in a more peaceful and comfortable environment, away from the street noise. Our staff also reported less stress and better communication. It was certainly a worthwhile investment.”

Final Thoughts

Evaluating acoustic glass from an expert’s perspective, I can affirm its effectiveness in sound insulation. Its advanced design and noise reduction capability make it a preferred choice in environments where noise reduction is paramount. However, its cost and individual requirements should also be factored in when considering its implementation.
