Acoustic Glass

Sound Pro is Glass Projects’ specialised acoustic laminated glass, meticulously engineered to reduce the transmission of unwanted sound, creating quieter and more comfortable interior environments. This high-performance glass typically consists of two or more lites of glass bonded together with a specially formulated acoustic Polyvinyl Butyral (PVB) interlayer. This interlayer has enhanced viscoelastic properties, meaning it is highly effective at dampening sound vibrations across a broad range of frequencies, particularly those commonly encountered in urban and transportation noise.

Key attributes of Sound Pro include:

• Superior Noise Reduction: Achieves significantly higher sound insulation performance compared to standard monolithic or laminated glass of equivalent thickness.

• Targeted Frequency Attenuation: The acoustic interlayer is designed to be particularly effective against common disruptive noises such as traffic, aircraft, and human voices.

• Enhanced Occupant Comfort: Contributes to increased well-being, productivity, and tranquility by minimising noise-induced stress and distractions.

• Versatile Integration: Sound Pro can be manufactured using various glass types (clear, tinted, Low-E, low iron) and can be toughened (Pro Tuf) for safety or incorporated into Insulated Glass Units (Pro Comfort) for combined acoustic and thermal insulation benefits.

• Safety Properties: Retains the inherent safety characteristics of laminated glass, as the interlayer holds glass fragments together in the event of breakage.

Glass Projects specifies Sound Pro for a wide array of applications in New Zealand where controlling noise intrusion or improving sound privacy is a critical design consideration. Its effectiveness makes it an ideal solution for:

• External Glazing in Noise-Sensitive Areas: Buildings located near busy roads, motorways, railway lines, airports, or industrial zones.

• Commercial Offices: For meeting rooms, executive offices, and open-plan spaces to enhance speech privacy and reduce distractions, fostering better concentration.

• Healthcare & Educational Facilities: Creating quieter, more healing or conducive learning environments in hospitals, clinics, schools, and universities.

• High-End Residential Properties: Providing a peaceful sanctuary from external noise in urban dwellings, apartments, or homes near noise sources.

• Specialist Applications: Recording studios, broadcast rooms, home theatres, libraries, and performance venues where acoustic integrity is paramount.

• Internal Partitions: To create acoustically isolated zones within a building, ensuring confidentiality and minimising sound transfer between spaces.

The Glass Projects team provides expert advice on the optimal Sound Pro configuration, considering the specific noise sources, required sound reduction levels (Rw or STC ratings), and the overall glazing system design to achieve the desired acoustic environment.
