developed a new wall system (patent pending) – the only wall system of its
kind – to successfully sound proofs your building without taking up excess
How the Acoustiflex Wall System (centre) compares in size to similar
systems from other manufacturers.
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.
The Acoustiflex Wall
System has been examined under the ‘Acoustic Performance Index’ and its
rating is extremely high. Acoustica says Acoustiflex Wall System is the
only system of its kind to achieve such a high rating for such a thin
wall. It is only 148mm wide and has an acoustic performance that can be
matched only by wall systems a great deal thicker (250-300mm). Acoustiflex
dampens any vibration generated in the plasterboard, resulting in a
greatly reduced ‘knocking’ effect. The wall feels solid and of good
quality construction. The Acoustiflex Wall System utilises very little
material, with only 2x13mm standard plasterboard on standard studs. It is
50-70 per cent cheaper to build than any other wall with the same acoustic
properties. 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. 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.
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.
