Level. A measure of the noise impact performance of a

C I – A spectrum adaptation term used to modify the
measured impact sound pressure level, Ln,w or L’nT,w.
Impact sound is generated by a laboratory grade tapping
machine placed on the floor to be tested. This tapping machine
does not accurately simulate the noise of a person’s foot steps
on the floor above, so the CI term was developed to more
closely simulate foot step noise.
The term is defined in ISO717-2. The Ln,w or L’nT,w alone
is sufficient to characterise concrete floors covered with
carpet. Other types of floors such as timber joist floors, bare
concrete floors or polished timber or tiles laid on concrete
floors require the CI term to properly characterise footstep
noise.
Timber joist floors can have a C I value slightly positive.
Concrete floors with an effective covering such as carpet
have CI terms approximately equal to 0dB. Concrete floors
with a hard, or less effective covering, can have CI terms
varying between –15dB and 0dB.
NRC – Noise Reduction Coefficient. A measure of the

ability of a material to absorb sound.
NRC is generally a number between 0 and 1. A material with
an NRC rating of 1 absorbs 100 % of incoming sound, that
is, no sound is reflected back from the material.
STC – Sound Transmission Class. A measure of the

sound insulation performance of a building element used
in the BCA prior to 2000. It is measured in very controlled
conditions in a laboratory.

Non Loadbearing Walls

Maximum wall heights are shown in Table B1 to B10. These

action of the frame and sheeting.
Non loadbearing walls in this manual have been designed
as follows:

Staggered stud walls using top hats are fixed to the base

Staggered stud walls using Rondo C studs must use the
CSR staggered stud clip to restrain the stud from twisting.
Wall tracks must be fixed to floors and ceilings at 600mm

a shear load of 0.75kN for a UDL of 0.25kPa and 1.1kN for
UDL of 0.35kPa.
Shaftwall™, SecurityWall™ and StrataWall™ systems have
additional installation details. Refer to the relevant installation
guide.
Tall residential buildings often have operable doors and
windows, resulting in internal walls being subject to wind
pressure. In these cases, walls must be designed for the
appropriate loads.

Gyprock® GFC external wall systems rely on a range of
cladding systems to provide weather resistance. There is a
range of effectiveness of these systems, and CSR Gyprock
recommends the cladding be installed with a drained cavity.
Cavity systems allow drainage and drying of any water
that penetrates, and are known to have good long-term
performance.
Sarking is also recommended to provide additional weather
protection to framing and lining.
External walls require specific design for condensation
control and energy efficiency, depending on the climate and
internal environment. Contact CSR Bradford for information

Gyprock Silencers™ has been assessed for up to FRL-–/120/120 in
CSIRO assessment FCO 2039. Mixer taps were positioned

When water supply services are installed within the Gyprock As an alternative to fire and acoustic rated power boxes,
Silencer™, cavitation and water hammer noise is reduced standard power points can be installed within Gyprock
by isolating the noise source from the linings on the other Silencers™. This reduces the labour intensive cutting and
side of the wall. The airborne noise that may leak into the caulking requirements of many other systems.
silencer cavity around taps is also contained.

showers can be 20-35 litres/minute. Flow control shower
heads are commonly available in 6, 9 and 12 litres per
minute output.
• Flow control washers are simple plastic discs that can
be fitted between the supply pipe and any shower, or tap
fitting. They have a small opening which in turn reduces
the water flow, and are available 6, 9 and 12 litres per
minute flow rates.
• Plastic pipes can also reduce the noise transmitted from
taps as they are not as rigid as copper pipes and transmit
less structure borne vibration.
The noise levels produced by various tap configurations in
systems using the Gyprock Silencer™ were measured in the
adjacent room. Typical results are presented in Table 1.
