Barrier: QuietWave® – Acoustic Barrier

• Multi-residential walls
• Retrofits
• High confidentiality partition wall systems (for lawyers and doctors offices)
• Commercial walls and ceilings
• Improving existing partition wall and ceiling performance
• Sole occupancy unit dividing walls
• Boardroom and office division walls
• Partition wall systems to block out confidential conversations

• Exceeds the Building Code of Australia (BCA) minimum requirements
• Can achieve the highest AAAC acoustic rating of 6 stars
• Thinnest and lightest possible wall system for the highest acoustic rating
• Most economical 6-star rating wall system available
• Effective for low frequencies to counter everyday noise from home audio and theatre systems
• Easily penetrated without compromising performance, a finished QuietWave® wall is solid and has similar resonance to masonry
• At just 1.2 mm thick QuietWave® provides a saving of 50% in the width of the wall against a comparable 6-star wall system and can be easily installed by just one person.

• QuietWave® technology is incorporated into Acoustica Projects’ range of acoustic products for walls, partitions, floors, ceilings and pipe lagging
• Consists of a flexible visco-elastic membrane and patented constrained layer membrane, combined with vibration damping material
• Group 1 fire rating
• Low VOC - less than a recognised threshold of 0.5mg for Green Star
• Maximum acoustic rating, thin and light profile
• Save costs and increase space
• Specifically designed for plasterboard walls - controls low frequencies and upper-mid frequencies which typically occur in plasterboard walls
• Standard roll size — 1.3m x 5.4m
• QuietWave® thickness — 1.2mm

Group 1 fire rating

VOC emissions: low VOC <5.0mg

Acoustic Performance Index – the cost of the wall compared to acoustic performance, wall thickness and floor space cost.

When Acoustica Projects’ concept of Acoustic Performance Index is applied to the QuietWave® wall system, the score is extremely high.

The QuietWave® wall system is only 148mm wide and has an acoustic performance that can ONLY be matched by the best wall system at 280-300mm wide.

System 1= QuietWave® sandwiched with 6.5mm plasterboard on both sides of a stud wall + 14kg/m3 insulation. Rw + Ctr = 41dB

System 2= QuietWave® sandwiched with 13mm standard plasterboard on both sides of a stud wall + 14kg/m3 insulation. Rw + Ctr = 46dB

System 3= QuietWave® sandwiched with 13mm Fyrchek plasterboard on both sides of a stud wall + 14kg/m3 insulation. Rw + Ctr = 51dB

Tests show that when sandwiched between two layers of 13mm Fire-check plasterboard the sound transmission loss achieved is equivalent to 5 layers of the same plasterboard.

The development of QuietWave® noise barrier has been achieved with a matching acoustic performance of R1,cw 27 for the 2.5kg/m2 (Wilkinson & Murray test results above).

QuietWave® has been certified by the CSIRO Division of Materials Science and Engineering as Group 1 Fire Rated.

Our tests show that when QuietWave® is sandwiched between two layers of 13mm Fyrchek plasterboard, the Sound Transmission Loss (STL) achieves is equivalent to 5 layers of the same plasterboard.
