Hush Glass

Hush glass is a specialized type of soundproof glass designed to reduce external noise and create quieter indoor environments. It is constructed using laminated glass technology, often incorporating acoustic interlayers that dampen sound vibrations. Hush glass is ideal for residential, commercial, and industrial spaces where noise reduction is a priority.

What is Hush Glass?

Hush glass is engineered to minimize sound transmission by using layers of glass bonded with specialized acoustic interlayers. These interlayers absorb sound vibrations, significantly reducing noise levels from traffic, construction, or other external sources.

  • Key Characteristics:
    • Superior sound insulation properties.
    • Often combined with other functionalities, such as UV protection or thermal insulation.
    • Suitable for both single-pane and double-glazed configurations.

How Effective is Hush Glass for Sound Insulation?

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.

How Does it Work?

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.

Features of Hush Glass

  1. Noise Reduction:

    • Reduces sound transmission by up to 70%, depending on thickness and construction.
  2. Versatility:

    • Can be customized to include tinted, Low-E, or decorative finishes without compromising acoustic performance.
  3. Durability:

    • Incorporates laminated glass technology, providing additional strength and safety.
  4. UV Protection:

    • Acoustic interlayers can also block harmful UV rays, protecting interiors.

Benefits of Hush Glass

  1. Enhanced Comfort:

    • Creates peaceful, quiet indoor environments, especially in urban or high-traffic areas.
  2. Improved Productivity:

    • Ideal for offices, reducing distractions and enhancing focus.
  3. Safety:

    • Laminated construction ensures that hush glass holds together when shattered, providing added security.
  4. Energy Efficiency:

    • Can be combined with insulated glass units (IGUs) to improve thermal performance.

Limitations of Hush Glass

  1. Higher Cost:

    • Hush glass is more expensive than standard or float glass due to its advanced acoustic properties.

  2. Weight:

    • Heavier than standard glass, which may require reinforced frames and supports.

  3. Limited Availability:

    • Custom orders may have longer lead times depending on the desired specifications
      .
  4. Not Soundproof:

    • While highly effective, hush glass does not completely eliminate noise but significantly reduces it.

Applications of Hush Glass

1. Residential Applications

  • Windows and doors in homes near busy roads, airports, or railways.
  • Bedroom windows and study rooms for enhanced peace and quiet.

2. Commercial Applications

  • Office buildings to improve employee focus and productivity.
  • Hotels and hospitals for guest comfort and patient recovery.

3. Industrial Applications

  • Factories and workshops to isolate noisy equipment areas.
  • Recording studios or meeting rooms for optimal sound management.

How Does Hush Glass Compare to Double Glazing?

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%.

Is Hush Glass Right for You?

Hush glass is an excellent solution for anyone seeking to reduce noise and create a more tranquil indoor environment. Whether for residential, commercial, or industrial use, hush glass combines soundproofing, safety, and customization to meet diverse needs. While it may have a higher upfront cost, the benefits of noise reduction and comfort make it a worthwhile investment.
