Introduction
CSR Gyprock™ Impact Damage Resistant Wall Systems
provide a higher degree of ‘soft body impact resistance’, that
is, resistance to the bumps and knocks which occur in high
traffic public buildings every day.
An important element in CSR Gyprock™ Impact Damage
Resistant Wall Systems is CSR Gyprock ™ Impactchek,
which is a purpose designed fibreglass bonded and mesh
reinforced plasterboard that exceeds the requirements of
the Building Code of Australia (BCA) for soft body impact
resistance.
Impact damage resistance is not directly related to acoustic
performance, and acoustic requirements should be
addressed as an additional issue where appropriate.
Advantages
• Soft body impact resistance in excess of the BCA strength
requirements.
• Can be used in fire rated systems.
• Can be used together with
standard 13mm plasterboard.
• Can be used effectively in
acoustic wall systems.
• Easy to install.
• Saves time and money compared
to other impact resistant wall
systems.
• Uses standard plasterboard
fasteners and fixing methods.
• Easy to joint and finish using
2
Applications
Gyprock ™ Impactchek plasterboard has been primarily
developed for use in areas that are required to be resistant
to soft body impact in accordance with the Building Code
of Australia Clause C1.8.
Although the highest impact damage resistance is only
required by the BCA in some Class 9 Building situations,
the inherent impact resistance of Gyprock™ Impactchek
plasterboard makes it ideal for all areas of high pedestrian
traffic in all building types, and it should be used wherever
there is a risk of impact damage. These risk areas include
corridors, foyers and stair shafts in commercial buildings,
shopping centres, cinemas, offices, sports stadiums,
schools, hospitals and nursing homes, and walls in public
transport structures such as railway stations or bus and
airport terminals.
Gyprock™ Impactchek plasterboard can also be used in
fire rated wall systems with a fire rating level (FRL) of up to
120/120/120 where higher impact damage resistance is
also required.
Gyprock™ Impactchek is also useful in acoustic wall systems
given the product’s high density.

Design
Considerations
FIRE RESISTANCE LEVEL.
The Fire Resistance Level (FRL) of a CSR fire rated wall
system will not be detrimentally affected by the substitution
of lining material as detailed in Table 1.
SYSTEM PERFORMANCE.
SOUND TRANSMISSION CLASS.
All wall configurations detailed in Table 2 have been
laboratory tested to establish their structural performance
characteristics.
The Sound Transmission Class (STC) of a CSR wall system
will not be detrimentally affected by the substitution of lining
material as detailed in Table 1.
To produce this specified performance, field installation of
these systems must comply with the stud spacings detailed
and all relevant installation detailing as specified in the
CSR Gyprock™ Fire & Acoustic Design Guide, NºGYP500
or the CSR Gyprock™ Steel Frame Wall Systems Installation
Guide, NºGYP544.
Where 13mm Gyprock Impactchek is used in lieu of 13mm
Gyprock Plasterboard CD, an improvement in the STC may
be experienced. Further technical assistance is available from
CSR designLINK™ telephone 1800 621 117.

An impact resistant wall system can be designed
and constructed from any wall system detailed in the
CSR Gyprock™ Fire & Acoustic Design Guide, NºGYP500,
by substituting Gyprock™ Impactchek plasterboard in lieu
of the specified CSR Gyprock™ Plasterboard products as
detailed in Table 1.
The Gyprock™ Impactchek must be applied to the traffic
side or sides of the wall in accordance with the BCA
requirements, and can be either the first or second layer in
two layer systems.
MINIMISING WALL DAMAGE.
To minimise the risk of wall damage from normal day-to-day
usage, the following items should be incorporated wherever
appropriate.
• Door Stops • Hand Rails • Crash Rails • Chair Rails.
