Hush Glass is a type of acoustic glass made by joining two sheets of glass with a acoustic interlayer specifically designed to dampen noise and outperforms ordinary glass in terms of sound insulation.
Hush glass can be used in place of standard glass to significantly improve sound insulation. It provides the same performance of heavy, thick glass but is much lighter.
An additional benefit of hush glass is that it blocks out 99% of UV radiation and reduces fading up to 8.5 times over normal glass.
Hush glass is over two times more effective in sound insulation when compared to normal laminated glass. Hush’s proprietary interlayer combines the dampening of airborne noise with the dampening of impact noise, resulting in exceptional sound insulation performance.
Hush glass targets specific frequencies to block out sound. The specially designed interlayer acts as a barrier, reducing vibrations caused by sounds with higher frequency ranges (the most sensitive range of human hearing). This means you can expect enhanced performance when Hush is used in places where noise is an issue, such as homes and offices.
Hush is ideal for the home office, nurseries, bedrooms, living rooms. It’s also great in hotel rooms where noise from neighbors can interrupt sleep or create problems when catching up with work after a busy day in the city. Hush glass is commonly used for healthcare facilities including hospitals and laboratories, where sound transmission must be kept to a minimum.
Double glazing consists of two layers of glass with a space between them filled with air or argon gas designed to increase energy efficiency and reduce noise. Double glazing still exceeds the performance of hush glass when it comes to both energy efficiency and noise reduction. However, double glazing makes the unit heavier (adding stress to window frames which potentially cause faster wear and tear) and is also more expensive than hush glass.
Hush glass is on average 25% less expensive than double glazed units and this makes it a practical and affordable option for many people.
Both hush and double glazing provide significant sound insulation over ordinary glass.
Modern double glazed units made for the primary purpose of noise reduction are now combined with hush glass which reduces noise up to 90%.
