QuietWave^® Drywall Acoustic Barriers

QuietWave^® is a high performance drywall noise barrier that delivers exceptional performance due to it’s patented constrained layer membrane.

Acoustica’s QuietWall system incorporating QuietWave^® delivers six star acoustic performance, a class above the BCA requirements, from the thinnest possible wall.

• Exceeds BCA minimum requirements for airborne sound insulation for a wall between attached dwellings
• Meets the highest possible AAAC acoustic rating of 6 stars
• Rw62 and Rw + Ctr = 55 dB
• With the thinnest possible wall section of 148 mm
• Most economic 6 star rating wall system available

The building code of Australia (BCA 2004) acoustic requirements introduced new and more onerous acoustic standards of Rw + Ctr = 50 dB for party walls between apartments, townhouses and other attached dwellings. Acoustica’s QuietWave^® wall system not only meets the minimum requirements of the new BCA code (equivalent to AAAC 5 star rating) but is a class ahead at AAAC 6 stars.

Acoustica’s QuietWave^® flexible visco-elastic membrane consists of a patented constrained layer membrane, combined with vibration damping material ‘floating’ elements. At just 1.2 mm thick it is easily handled and can be installed by just one person.

The QuietWave^® flexible visco-elastic membrane can be penetrated without any degradation in performance. The finished wall system has a solid feel and when impacted upon, sound resonates similar to a masonry wall.

QuietWave^® increases the low frequency performance of the wall system to counter noise from entertainment sources such as home theatres and any other electronic entertainment noise.

QuietWave^® also controls the large coincidence dip in the upper-mid frequency region of 2500 - 4000 Hz, which typically occurs in plasterboard walls.
