Laminated Construction
Acoustic glass typically consists of two or more layers of glass bonded together with a specialized sound-control interlayer. This interlayer is designed to absorb and dissipate sound waves, reducing noise transmission.
Acoustic Glass
Acoustic glass is specially designed laminated glass that reduces noise transmission. It consists of two or more glass layers with an acoustic interlayer, typically polyvinyl butyral (PVB) or a specialized sound-dampening resin, which absorbs and dampens sound waves.
Acoustic Glass
Thompson Innovative Glass manufactures Acoustic glass that is specially designed & engineered to reduce sound transmission, making it ideal for environments where sound insulation is important.
It is commonly used in buildings that may have high levels of noise pollutions surrounding it (busy highway, railways, airports, etc.) or applications needing sound privacy (medical, manufacturing, security, etc.)
Key Features
Thickness
Varying glass thicknesses in the layers of glass and the size of the airspace in an insulating glass unit can further disrupt sound waves, enhancing acoustic performance.
Transparency
Despite its soundproofing properties, acoustic glass maintains high levels of transparency, making it suitable for applications where visibility is important.
How Acoustic Glass Works
The laminated glass make-up of acoustic glass plays a key role in reducing soundwaves into the structure.
Sound Attenuation
The specialized interlayer in acoustic glass reduces the vibration of sound waves as they pass through the glass, lowering the sound transmission class (STC) rating.
Frequency Filtering
Acoustic glass is particularly effective at reducing mid-to-high-frequency noise, such as traffic, voices, or industrial sounds.
Key Benefits
Noise Reduction
Significantly decreases external noise, creating a quieter and more comfortable indoor environment.
Safety
Like standard laminated glass, the sound-control interlayer.will hold the glass together in post breakage scenarios, preventing glass shards from flying.
Customizability
Available in various thicknesses, colors, and coatings (e.g., Low-E or solar control) to meet aesthetic and thermal performance building requirements.
Frequently Asked Questions About Acoustic Glass
What is acoustic glass?
Acoustic glass is specially designed laminated glass that reduces noise transmission. It consists of two or more glass layers with an acoustic interlayer, typically polyvinyl butyral (PVB) or a specialized sound-dampening resin, which absorbs and dampens sound waves.
How does acoustic glass work?
Acoustic glass blocks sound by using multiple layers and a noise-dampening interlayer to disrupt and reduce sound waves. This prevents noise from passing through, making spaces quieter.
What types of noise does acoustic glass reduce?
Acoustic glass is effective against traffic noise, aircraft noise, construction sounds, voices, and other environmental disturbances.
Is acoustic glass the same as double glazing?
Not exactly. Double glazing consists of two panes of glass separated by an air or gas-filled space, which provides some sound insulation. Acoustic glass, however, uses a special interlayer for superior noise reduction, making it more effective than standard double glazing.
How much noise can acoustic glass reduce?
Acoustic glass can reduce noise by up to 40–50 decibels (dB) depending on the thickness and composition. Standard double glazing typically reduces around 30–35 dB, while laminated acoustic glass offers higher sound insulation.
What is the Sound Transmission Class (STC) rating of acoustic glass?
Acoustic glass typically has an STC rating between 35 and 50, depending on thickness and composition. The higher the STC rating, the better the sound insulation.
Does acoustic glass work better than regular laminated glass for noise reduction?
Yes. While standard laminated glass provides some sound reduction, acoustic laminated glass has a specially designed interlayer that enhances noise reduction, making it more effective than regular laminated glass.
Can acoustic glass block low-frequency noises, like bass sounds?
Yes, but low-frequency sounds (such as bass from music or heavy machinery) are harder to block. Thicker glass and multi-layered acoustic glazing systems are more effective against low-frequency noise.
Does acoustic glass qualify for building regulations or noise control requirements?
Yes, in many areas, acoustic glazing is required in noise-sensitive locations, such as near airports or busy roads, to meet building codes and noise mitigation standards.
