GypWall partitions provide an economical method of space
division and weigh much less than masonry partitions of
comparable thickness, thus also effecting savings in
structural design.
GypWallTM partitions are cost-effective, multi-purpose
partitions that are suitable for all types of buildings.
The system consists of Gyproc plasterboards screw-fixed to
Gypframe metal sections. The partitions are extremely
versatile and can achieve a range of fire resistance, sound
insulation, robustness and maximum height requirements
required for most normal building types. Their open cavity
construction can accommodate the inclusion of services
during construction.

GypWall™
T 00353 1 629 8400
Gypframe Floor & Ceiling Channel is fixed at the head and
base. Gypframe studs are fitted vertically to a friction-fit
within the channel sections, and to abutments, to form the
framework. This allows for adjustment during boarding.
Studs are fitted so as to all face the same way. Additional
framing is installed as required to support heavy fixtures.
Boards are screw-fixed to framing members to form the
lining. Horizontal board-end joints of face lining boards
should be backed with Gypframe GFS1 Fixing Strap or
Gypframe GFT1 Fixing ‘T’ .

Partition duty - strength and robustness
The duty ratings have been calculated in accordance with
BS 5234: Parts 1 & 2: 1992. The rating is a measure of the
ability of the wall to meet the requirements of four
strength and robustness tests: door slam, soft body impact,
hard body impact, and stiffness. Grades, e.g. ‘Medium
Duty’, relate to the level of activity in adjacent areas and
the degree of care likely to be exercised in them. The
requirements are for walls complete with their surface
finishes where these are part of the wall specification.
Other optional tests may also apply.
Using the duty of a particular wall, the designer can select
a wall for its area of use (with due consideration for fire,
sound, or thermal requirements). Please refer to Table 2.
Table 2 - Wall grades by categories of duty

PERFORMANCE
Environmental
GypWall partitions are unsuitable for use in areas subject to
continuously damp or humid conditions.
Plasterboards are not suitable for use in temperatures above
49ºC but can be subjected to freezing conditions without risk
of damage.
Fire protection
For reaction to fire classifications for Gyproc and Glasroc
boards please refer to Section 2.1 .
Fire resistance
The fire resistances given in Tables 3 - 11 are for
imperforate partitions tested to BS 476: Part 8: 1972 or BS
476: Part 22: 1987 or assessments based on these tests.
Sound insulation
The Rw ratings given in Tables 3 - 11 are for imperforate
partitions and have been tested in accordance with
BS EN ISO 140-3: 1995, and rated in accordance with
BS EN ISO 717-1: 1997 or assessments based on these tests.
Airtightness is essential for optimum sound insulation.
While most junctions will be sealed by standard jointing
materials, gaps at the base of the partition and other small
airpaths can be sealed using Gyproc Sealant.

CONSTRUCTION DETAILS
General notes to the Performance tables which follow (Tables 3 - 11)
The fire resistance and sound insulation performances are for imperforate partitions incorporating boards with all joints taped and finished
according to Gypsum Industries’ recommendations.
The quoted performances are achieved only if Gypsum Industries components are used and the Company’s fixing recommendations are strictly
observed. Any variations required to the specification should be checked with Gypsum Industries.
Nominal thicknesses given are subject to tolerances on associated materials (Please see also Door openings in DESIGN).
3.2
92
Gypframe studs are available in bespoke lengths on request from Gypsum Industries to satisfy large projects. Please contact Gyproc
at 01 629 8400.
In respect of BS 5234, duty is directly related to maximum recommended partition height, and account should be taken of methods of fixing to
adjoining structures.

DESIGN
Please refer to Section 3.1 - Introduction for general
considerations.
Planning - key factors
The position of service penetrations such as ducts and fire
dampers should be pre-determined, and their installation
planned into the frame erection stage. All penetrations
will need to be adequately fire-stopped if integrity is to be
maintained in the event of fire.
Maximum heights
The criteria to determine the recommended maximum
partition heights are based on a limiting deflection of
L/240 at 200Pa with studs at 600mm centres, together with
criteria within BS 5234: Parts 1 & 2: 1992. Greater heights
can be achieved under different criteria. Please contact the
Technical Sales Department.
Cavity barriers
Perimeter cavity barrier
The Gypframe Floor and Ceiling Channels can be
considered satisfactory closures to flame and smoke,
abutting ends of channel may, however, require firestopping. Continuity of the barrier should be maintained
with short lengths of 12.5mm Gyproc plasterboard cut to a
good fit, screwed into the web and across the ends of the
channels to prevent direct communication to an adjoining
cavity. A continuous timber sole or head plate would
provide an alternative solution.
Where studs require to be closed because of the cut-outs in
the web, 12.5mm plasterboard cut to a good fit should be
screwed to the web of the stud. Where the partitions abut
other plasterboard, a cavity closure is not necessary.
Vertical cavity barrier
Gyproc plasterboard 12.5mm thick, cut to a good fit and
continuous, is screwed to the web of individual studs.
Please refer to section 3.9 for further information.
Service penetrations
Penetrations of fire resistant constructions for services need
careful consideration to ensure that the integrity of the
element is not impaired and also that the services
themselves do not act as the mechanism of fire spread.
It is important to use only those services and their
installations which have been shown by fire test to be able
to maintain the integrity of the construction.
In most situations the services will be installed by
contractors other than the dry lining contractor. It is
important, therefore, that all relevant contractors should
be advised as to where and how their service penetrations
should be made and maintained.
The necessity to independently support services will depend
on their size and weight. Please contact the Technical Sales
Department for guidance.
Dampers / ducts
When designing for the installation of fire dampers and
associated ductwork through a GypWall partition,
consideration should be given to the size and weight of
the damper. This will determine whether it can be
supported directly from the partition or needs to be
independently supported from the structure. Test evidence
and advice is available from the Technical Sales Department
to cover a number of situations including direct support
from the partition and also where the damper is offset
from it. 1 Specific advice on the fixing of the damper
should be obtained from the damper manufacturer. Please
refer to CONSTRUCTION DETAILS, Figs 20 and 21.

Wind loading
GypWall partitions are non-loadbearing but can accept a
degree of wind loading, for example when used in
buildings with large or multiple external doors.
Information can be provided on specifications to suit
individual requirements, including the provision of
deflection heads.
Deflection heads
Partition head deflection designs may be necessary to
accommodate dead load or live load deflections in the
supporting floor and/or roof construction and differential
floor loadings. This can be in the form of live loads on
intermediate floors creating a + condition or a simple minus
deflection for dead loads on the structural floors.
Deflection heads may also be required to the underside of
roof structures subjected to positive and negative pressures.
GypWall partitions can incorporate head deflection designs
to accommodate structural deflection (please see Figs 16 to
19). Where greater deflection needs to be accommodated,
please contact the Technical Sales Department for guidance.
By designing service zones through which all services pass,
the number of individual service penetrations can be
minimised. Service zones can be sealed after installation
of the services using a tested and substantiated
fire-stopping system.

Deflection heads (cont’d)
Deflection heads, by definition, must be able to move and
therefore, achieving an airtight seal is difficult. Inevitably,
this will have a detrimental effect on the acoustic
performance of any wall which incorporates deflection at
the head. The approach shown in Section 4.1 - GypWall
STAGGERED could be considered to minimise loss of
performance. In most cases, a suspended ceiling will also
assist in minimising loss of performance.
Fixing floor and ceiling channels
Floor channels must be securely fixed with a row of fixings
at 600mm maximum centres. With 148mm and 94mm
channels, two rows of staggered fixings are required, each
row at 600mm centres and each fixing 25mm in from the
flange. If the floor is uneven a 38mm thick timber sole
plate equal to the width of the channel should be used. If
the concrete or screeded floor is new, consideration should
be given to the installation of a damp proof membrane
between the floor surface and the channel or sole plate.
Head channels must be securely fixed at 600mm maximum
centres. With 148mm and 94mm channel, two rows of
staggered fixings are required, each row at 600mm centres
and each fixing 25mm in from the flange. Extra support
may be necessary to provide positive fixing points with
some constructions.
Door openings
The designer should consider thickness tolerances of the
partition types in relation to the proposed door frame
detail. A standard door frame is formed by locating
full-height studs each side of the opening. The head is
formed from a section of channel fixed to the studs on
each side. The opening is then lined with 38mm thick
timber cut to the width of the stud (see Fig 14). Where
additional provision is required to support heavy doorsets
contact the Technical Sales Department for guidance.
To satisfy BS 5234: 1992 requirements for strength and
robustness, door framing should be specified as shown in
Fig 15. These constructions pass the ‘door slam’ test where,
for a given duty, the deflection of the door frame is
measured after a set number of slams (e.g. for Heavy and
Severe Duty partitions, 100 slams of a 60kg door). Doors,
frames and doorsets should be fixed in accordance with
manufacturers recommendations.

Control joints
Control joints (please see Fig 11) may be required in the
partition to relieve stresses induced by expansion and
contraction of the structure. The location of control joints
is at the discretion of the specifier. It is recommended
that they coincide with movement joints within the
surrounding structure.
Installation of services
The cut-outs in the studs can be used for routing electrical
and other small services (please see Fig 1). Where
AcouStuds are used, services are routed through ‘H’ shaped
push-outs, 50mm x 28mm at the same centres as shown in
Fig 1 for conventional cut-out. Cables should be protected
by conduit, or other suitable precautions taken to prevent
abrasion when they pass through the metal frame.
Services must be installed in accordance with all available
standards, guidelines and recommendations.
Fixtures
Lightweight fixtures can be made directly to the partitions.
Medium weight fixtures can be made to Gypframe 99 FC 50
Fixing Channel. Heavy fixtures should be made to
independent framing installed before boarding.
Ceramic tiles
Ceramic tiles up to 12.5mm thick with a maximum weight
of 32kg/m2 can be applied using thin bed adhesives (usually
3mm thick). Stud centres will normally require closing
down. Please refer to Section 2.3 - Ceramic tiling.
Board finishing
Please refer to Section 1.5 - Finishing Coat Plasters,
Section 2.2 - Jointing, and Section 2.5 - Decorative
effects.
Estimating
The estimated construction time is 2 - 3m2 / hour (single
layer partition) or 1.5 - 2m2 / hour (double layer partition)
ready for finishing.
