Acoustica™ has developed a new incredibly thin & soundproof (patent pending) wall system.
The Acoustiflex® wall system has the highest acoustic performance rating for any wall under 150 mm thick providing Rw 60 or higher. Thickness is a very important consideration as the floor space in a typical apartment is $6000 per square metre. The Acoustiflex® Wall System, however, is only 148 mm wide & has an acoustic performance that can be matched only by wall systems a great deal thicker (250-300 mm).

Acoustiflex® is a specially engineered product designed for use in noise insulation. It consists of a flexible ‘calcium carbonate’ loaded polymeric elastomer, supported by a polyester film with reinforced aluminum foil on one side & a non-woven polyester fabric on the other. Acoustiflex® offers high mass to stiffness ratio & because of its limpness has excellent low & high frequency sound attenuation.
Acoustiflex® is fire-rated & tested by C.S.I.R.O. It is strong, tear resistant, flexible & economic.
Acoustiflex® increases low frequency performance by damping of the plasterboard panel. Acoustiflex® is also used to control the large coincidence dip in the upper-mid frequency region of 2500-4000 Hz which typically occurs in plasterboard walls.
As demonstrated by extensive testing, there is drastic improvement in the nominated frequency regions when the F2.5 Acoustiflex® is added between two sheets of 13 mm normal density plasterboard. The performance gain at the coincidence dip frequency is 9 dB, for the application of the f2.5 Acoustiflex®, with significant gains occurring above this frequency.
The Acoustiflex® Wall System is the ONLY system of its kind to achieve this very high result for such a thin wall.
Acoustiflex® Wall System has been examined under the “Acoustic Performance Index’ & its rating is extremely high. ‘Acoustic Performance Index’ takes into account the cost of the wall compared to its acoustic performance, the thickness of the wall & the floor-space cost.
