GypWallTM STAGGERED
GypWall STAGGERED is a lightweight, non-loadbearing
partition system which offers high levels of sound
insulation performance.
Subject to Local Authority approval, GypWall STAGGERED
can be used as the separating walls between residential
units, such as flats and apartments, to meet the
requirements of the national Building Regulations. The
system can also be specified in commercial and industrial
buildings to meet specific standards of sound insulating
performance in situations where space is at a premium.
GypWall STAGGERED consists of a Gyproc ‘I’ Stud
framework in which alternate studs are staggered within
the floor and ceiling channels to provide a degree of
separation from one face of the partition to the other. Two
options are available Gypframe 60I70 ‘I’ Studs staggered
within Gypframe 72mm Floor & Ceiling Channel (the 60/72
series), or Gypframe 92I90 ‘I’ Studs staggered within
Gypframe 148mm Floor & Ceiling Channels (the 92/148
series). Proprietary Gypframe Spacer Clips are used to retain
the studs within the Floor & Ceiling Channels. Isover
Acoustic Roll is included in the cavity and the staggered
stud framework is lined on both sides with Gyproc
SoundBloc.

INSTALLATION
For full installation details, refer to the Installation Guide at www.gypsum.ie
Gypframe Floor & Ceiling Channel is fixed to the floor and
soffit. Gypframe ‘I’ Studs are fitted vertically into the
channel sections and held in place by spacer clips.
Alternate studs are staggered (offset). As the spacer clips
are friction fitted this allows for stud adjustment during
boarding. Gypframe ‘C’ Studs are fixed at abutments.
Isover insulation is fitted between studs and the perimeter
sealed using Gyproc Sealant.
Boards are screw-fixed to alternate offset studs to form the
lining. Horizontal board end joints of face layer boards
should be backed with Gypframe GFS1 Fixing Strap or
Gypframe GFT1 Fixing ‘T’.

PERFORMANCE
EnvironmentalGyproc GypWall STAGGERED staggered stud partition is
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 Glasrocboards please refer to Section .
Fire resistance The fire resistances given in Table 2 are for imperforate
partitions tested to BS 476: Part 8: 1972 or BS 476: Part 22:
1987 or assessments based on these tests. Partitions were
tested without timber sole plates.
Sound insulationThe Rw ratings given in Table 2 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.
Partition duty – strength and robustnessThe duty ratings given in Table 2 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).
DESIGN
Refer to section 3.1 - Introduction, for general
considerations.
Maximum heightsThe criteria to determine the recommended maximum
partition heights are based on a limiting deflection of
L/240 at 200Pa, together with criteria within
BS 5234: Parts 1 & 2: 1992. Greater heights can be achieved
under different criteria. Contact the Technical Sales
Department for guidance.
Cavity barriersWhere a cavity barrier is required, a rock mineral wool strip
cut neatly to fit across the cavity forms a suitable closure.
Acoustic performanceThe partition achieves high levels of sound insulation by
virtue of the mechanical separation between the two rows
of studwork. It is important, therefore, that this isolation is
maintained, and that services, fixtures, etc, do not form a
bridge between the two sets of linings.
Fixing floor and ceiling channelsThe channels must be securely fixed to the surrounding
structure at 600mm maximum centres. 148mm Gyproc
Channels must be fixed with two rows of staggered fixings,
each row at 600mm centres, and each fixing 25mm in from
the flange. If necessary, additional provision should be
made to provide positive fixing points.
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.
Deflection headsPartition head deflection designs may be necessary to
accommodate dead load or live load deflections in the
supporting floor and/or roof construction. 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
at the underside of roof structures subjected to positive
and negative pressures. Gyproc GypWall STAGGEREDstaggered stud partitions can incorporate head deflection
designs to accommodate supporting structural deflections
with only a slight reduction in sound insulation
performance (1 - 2dB). See Figs 1 and 2.

4.1
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.
Service penetrationsPenetrations 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.
The inclusion of service penetrations, socket boxes etc in a
separating wall is not recommended as the sound
insulation may be downgraded.
Installation of servicesThe installation of services should be carried out in
accordance with all available standards, guidelines and
recommendations. Cables should be protected by conduit,
or other suitable precautions taken, to prevent abrasion
when they pass through the metal frame.
Switch boxes and socket outlets can be supported on
brackets formed from Gyproc Fixing Channel or cut and
bent channels fixed horizontally between the studs.
Door openingsAny openings will require very careful detailing if the
acoustic performance of the partition is to be maintained.
Specialist heavy acoustic doorsets may require additional
support. Contact the Technical Sales Department
for guidance.
FixturesLightweight fixtures can be made directly to the partition
lining. Medium weight fixtures can be made to Gyproc
Fixing Channel. Heavy fixtures should be made to
independent timber framing which is installed at the frame
erection stage. The timber member should be notched at
the intermediate stud position. Any contact at this point
will downgrade the acoustic performance of the partition.
Control jointsControl joints may be required in the partition to relieve
stresses induced by expansion and contraction of the
structure. The location of the control joints is at the discretion
of the specifier. It is recommended that they coincide with
movement joints within the surrounding structure.
Ceramic tilingCeramic 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. Refer to section - Ceramic tiling.
Board finishingRefer to section - Finishing Coat Plasters, section
- Jointing, and section - Decorative effects.
EstimatingThe estimated construction time is 2 - 2.5m2 / man hour
(single layer partition) or 1.5 - 2.5m2 / man hour (double
layer partition) ready for finishing.

Gypframe Floor & Ceiling Channels are fixed at the head
and base to achieve the specified wall thickness. Gypframe
‘C’ Studs are fitted vertically to friction-fit within the
channel sections and to abutments, to form the
framework. This allows for adjustment during boarding.
Studs should be fitted to face the same way and extended
by splicing to the specified height. Additional framing is
installed as required to support heavy fixtures. Where
specified, mineral wool is installed into the cavity-formed
frameworks. The frames are braced using Gypframe GAB3
Acoustic Braces or solid braces formed from Gypframe 99
FC 50 Fixing Channel at specified centres. Gyproc Sealant is
applied to the frame perimeters to seal airpaths. Boards are
screw-fixed to framing members to form the lining.
Horizontal board-end joints in face layer boards should be
backed with Gypframe GFS1 Fixing Strap.

EnvironmentalGyproc GypWall AUDIO is 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 protectionFor reaction to fire classifications of Gyproc Plasterboards,
please refer to section 2.1 .
Fire resistance The fire resistances given in Table 2 are for imperforate
walls tested to BS 476: Part 8: 1972 or BS 476: Part 22: 1987
or assessments based on these tests.
Gyproc GypWall AUDIO provides up to 120 minutes fire
protection to structural steel dependant upon the lining
specification and steel section factor. Table 3 gives the fire
protection periods for different configurations.

Sound insulationThe Rw ratings given in Table 2 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.
Airtightness is essential for optimum sound insulation.
While most junctions will be sealed by standard jointing
materials, gaps at the base of the wall and other small
airpaths can be sealed using Gyproc Sealant. For specific
applications, the sound insulation performance at certain
frequencies may be important. Contact the Technical Sales
Department for guidance.
Other high performance acoustic wall specifications are
possible with masonry construction lined with Gyproc
plasterboards. Contact the Technical Sales Department for
details.
Partition duty – strength and robustness
All the wall specifications given in Table 2 achieve a Severe
duty rating 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. The Duty grade relates to the level of activity in
adjacent areas and the degree of care likely to be exercised
in them. Severe duty is appropriate where the adjacent
space is intensively used by the public and others with little
incentive to exercise care. It could be prone to vandalism
and abnormally rough use. 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). Refer to Gyproc GypWall,
PERFORMANCE, for further information on duty rating.

DESIGN
Refer to section 3.1 Introduction, for general
considerations.
Maximum heightsThe criteria to determine the recommended maximum
partition heights given in Table 2 are based on limiting
deflections of L/240 and L/125 at 200Pa, together with
criteria within BS 5234: Parts 1 & 2: 1992.
Cross-bracingLaboratory tests were carried out on walls without bracing.
The results, however, are a realistic representation to site
conditions in which Gyproc Fixing Channel cross-braces are
fitted at the recommended 3600mm maximum centres,
provided that appropriate measures are taken on site to
eliminate flanking sound transmission. Test evidence is
provided by British Gypsum report ATR 1299 where site tests
on a large Multiplex cinema wall achieved comparable
performance to the equivalent specification tested in the
laboratory without bracing.
Some acoustic designers prefer the option of a resilient
acoustic brace. The Gyproc GAB3 Acoustic Brace has been
shown by test not to downgrade acoustic performance in
laboratory conditions. As a result of the mechanics of this
brace, however, fixing centres should be reduced from
3600mm to 3300mm, staggered by 1200mm. Maximum
recommended wall heights will be reduced – refer to
Table 2.
Cavity barriersStone mineral wool cut neatly to fit across the cavity will
form a suitable closure.
Service penetrationsPenetrations of fire resistant or sound insulating
constructions for services need careful consideration to
ensure that the performance of the element is not
downgraded, and also that the services themselves do not
act as the mechanism of fire spread or sound transmission.
Deflection headsPerformance details apply to fixed head constructions.
If deflection is required to be accommodated, contact the
Technical Sales Department for suitable detailing.
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 Gyproc
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 channelsThe channels must be securely fixed with two rows of
staggered fixings (fixings at 600mm maximum centres and
25mm in from the flange in each row). 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.

Control jointsControl joints 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 servicesThe installation of services should be carried out in
accordance with all available standards, guidelines and
recommendations. Cables should be protected by conduit,
or other suitable precautions taken, to prevent abrasion
when they pass through the metal frame. Switch boxes or
socket outlets should be avoided - however, where this is
not possible contact the Technical Sales Department for
further guidance.
Door openingsAny openings will require careful detailing if the acoustic
performance is to be maintained. Specialist heavy acoustic
doorsets may require additional support. Contact the
Technical Sales Department for guidance.
FixturesLightweight fixtures can be made directly to the linings.
Medium weight fixtures can be made to Gyproc Fixing
Channel. Heavy fixtures should be made to independent
framing with the extra supports installed at the frame
erection stage.
Ceramic tilingCeramic 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. Refer to section 2.3 - Ceramic tiling.
Board finishingRefer to section 1.5 - Finishing Coat Plasters, section 2.2
- Jointing, and section 2.5 - Decorative effects.

EnvironmentalGyproc GypWall SECURE is 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 protectionGyproc MultiBoard is non-combustible when tested to
BS 476: Part 4: 1970 (1984). The board surfaces also
achieve a Class 0 rating for the purposes of national
Building Regulations.
Fire resistanceThe fire resistances given in Table 2 are for imperforate
walls tested to BS 476: Part 8: 1972 or BS 476: Part 22: 1987
or are assessments based on these tests.
Sound insulationThe Rw ratings given in Table 2 are for imperforate
partitions and have been tested in accordance with
BS EN ISO 140-3: 1995, and rated in accordance with

Partition duty – strength and robustnessThe duty rating given in Table 2 has been estimated to
comply with BS 5234: Parts 1 and 2: 1992. The rating is a
measure of the ability of the partition to meet the
requirements of four strength and robustness tests: door
slam, soft body impact, hard body impact and stiffness. It
relates to the level of activity in adjacent areas and the
degree of care likely to be exercised in them. The
requirements are for partitions complete with their surface
finishes where these are part of the partition specification.
Other optional tests may also apply (not including security).

PERFORMANCE DESIGN
Refer to section 3.1 Introduction, for general
considerations.
Planning – key factorsThe overall partition width is 70mm, subject to tolerances
on associated materials.
Maximum heightsThe criteria to determine the recommended maximum
partition heights are based on a limiting deflection of
L/240 at 200Pa, together with criteria within
BS 5234: Parts 1 & 2: 1992. Contact the Technical Sales
Department for guidance.
SecurityThe excellent mechanical properties of Gyproc MultiBoard,
combined with the stiffness and resilience of the
Security Sheet, make Gyproc GypWall SECURE a formidable
barrier to entry. It has a high resistance to ‘determined
attack’ and vandalism using hand tools, and good
resistance to attack using power tools.
Ad-hoc tests have been carried out at British Gypsum’s
Building Test Centre. A ‘determined attack’ by a team of 4
using hand tools did not achieve through penetration until
approximately 10 minutes.
Where even greater resistance to attack is required, 0.7mm
flat galvanised steel sheet (by others) can be fixed to
Gyproc Security Sheet prior to boarding.
Cavity barriersContinuous steel angles at the head and base provide
horizontal cavity barriers, whilst the ribs in the security
sheet provide a vertical cavity barrier to the passage
of flames.
Head and base fixingGyproc GA4 Angles are fixed to the sub-structure using
suitable proprietary fixings (e.g. Rawl R-SPT Throughbolt)
at 300mm centres.

ServicesWhilst services can be installed, these should be kept to a
minimum. The installation of services should be carried out
in accordance with all available standards, guidelines and
recommendations. Services are easily accommodated
vertically between the ‘ribs’ of the sheeting. Holes can be
formed in the security sheeting to enable services to be
passed horizontally. These should be minimised in order to
maintain structural performance and where possible service
penetrations should be concealed either above suspended
ceiling level or behind an associated lining.
FixturesLightweight fixtures can be made directly into Gyproc
MultiBoard. Medium weight fixtures can be made through
the lining into the ‘high points’ of the security sheet core.

Gypframe Floor & Ceiling Channel is fixed to the floor and
soffit. Gypframe studs are fitted vertically to a friction-fit at
600mm centres within the channel sections, and to
abutments, to form the framework. This allows for
adjustment during boarding. Gypframe ‘C’ Studs are fitted
so as to all face the same way. Additional framing is
installed as required to support heavy fixtures.
Gyproc DuraLine boards are screw-fixed to all framing
members to form the lining. Horizontal board-end joints
should be backed with Gypframe GFS1 Fixing Strap or GFT1
Fixing ‘T’.
INSTALLATION

DESIGN
Planning – key factorsThe 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.
Maximum heightThe criteria to determine the recommended maximum heights
are based studs at 600mm centres, with a limiting deflection of
L/240 at 200Pa, together with criteria within BS 5234: Parts 1 &
2: 1992. Greater heights can be achieved under different
criteria. Contact the Technical Sales Department.
Service penetrationsPenetrations 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.
Wind loadingGypWall ROBUST 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.
Contact the Technical Sales Department for guidance.
Deflection headsDeflection 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 - 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 channelsFloor channel must be securely fixed with a row of fixings
at 600mm maximum centres. 94mm channels require two
rows of staggered fixings, at 600mm centres in each row. 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.

PERFORMANCE
EnvironmentalGyproc DuraLine is 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 resistanceThe fire resistances given in Table 2, 3 and 4 are for
imperforate partitions tested to BS 476: Part 22: 1987 or
assessments based on these tests.
Sound insulationGyproc DuraLine boards provide high levels of sound
insulation when used in Gypsum Industries’ systems. The
sound insulation performance of GypWall ROBUST partitions
can be increased with the inclusion of Isover Acoustic Roll,
Isover Modular Roll or Isover Steel Infill Batts in the cavity
(see Table 2, 3 and 4).
Partition duty – strength and robustnessThe duty ratings given in Table 2, 3 and 4 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).

Door openingsThe designer should consider the thickness tolerances of the
partition types in relation to the proposed door frame
detail. A standard door opening is formed by locating
full-height Gypframe 70 S 60 or 92 S 60 ‘C’ Studs each side
of the opening. The head is formed from a section of
Gypframe 72 DC 60 or 94 DC 60 Deep Flange Floor and
Ceiling Channel fixed to the studs on each side. The
opening is then lined with 38mm thick timber cut to the
width of the stud.
To satisfy BS 5234 requirements for heavy duty partitions,
door framing should be specified as shown in
CONSTRUCTION DETAILS, Fig 6. Gypframe 70 S 60 or 92 S 60
‘C’ Studs are located each side of the opening and cloaked
to door height with channel section. 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).
Exceptionally heavy doorsets may require additional
provision. Contact the Technical Sales Department if further
guidance is required.
Control jointsControl joints 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.
FixturesIn high usage areas, where misuse may be a potential
problem, heavy fixtures such as wall-mounted sanitary ware
should ideally be backed by framing members.
This can be achieved by fixing into the metal studs, or to
additional framing or timber noggings.
Ceramic tilesCeramic 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. Refer to section - Ceramic tiling.
FinishingRefer to section - Finishing Coat Plasters, section -
- Jointing, and section - Decorative effects.
EstimatingThe estimated construction time is 1 - 1.5m2 / man hour
ready for finishing.

Key facts
GypWall EXTREME is an ultimate impact resistant partition
system for use where even ‘severe duty’ will not suffice. The
system provides a lightweight, cost-effective,
non-loadbearing partition suitable for areas subject to
intensive traffic.
Using only a minimum number of components,
GypWall EXTREME consists of Gyproc Rigidur boards screw
fixed to a lightweight Gypframe stud framework. The
durability and impact resistance of the boards is provided
through the unique combination of recycled cellulose fibres
and dense gypsum.
GypWall EXTREME is fully compatible with GypWall robust
and other Gyproc partition systems. In addition, in double
layer board linings, Gyproc Rigidur is specified as the outer
face layer only. Allowing significant savings on both
material and installation cost.

Gypframe Floor & Ceiling Channel is fixed to the floor and
soffit. Gypframe studs are fitted vertically to a friction-fit at
600mm centres within the channel sections, and to
abutments, to form the framework. This allows for
adjustment during boarding.
Gypframe ‘C’ Studs or Gypframe AcouStuds are fitted so as
to all face the same way. Additional framing is installed as
required to support heavy fixtures.
Inner layer
In double layer systems, inner layers of Gyproc
plasterboards should be fixed with 25mm Gyproc Drywall
Screws around the perimeter of the board at 300mm
centres, and at the intermediate stud at 600mm centres.
In single layer systems, Rigidur boards are fixed using
40mm Rigidur Screws at 300mm centres around the
perimeter of the board, and at the intermediate stud
positions, at least 13mm from the edge of the board. When
using Rigidur boards, always fix from the bottom of the
partition upwards, as per best practice.
Outer layer
Rigidur boards are fixed using 40mm Glasroc Rigidur
Screws at 300mm centres around the perimeter of the
board, and at the intermediate stud positions, at least
13mm from the edge of the board.

PERFORMANCE
EnvironmentalGypWall 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 resistanceGyproc Rigidur achieves an A1 Euroclass reaction to fire
classification and Class O in accordance with Technical
Guidance Document 13 (Fire).
The fire resistances given in Table 2 and 3 are for
imperforate partitions. Note that the insulation in
detail is required for fire resistance as well as sound
insulation claims.
Sound insulationThe mass and sound insulating qualities of Gyproc Rigidur
enable high acoustic performances to be achieved.
The sound insulation performance of GypWall EXTREME
partitions can be further increased with the inclusion of
Isover Acoustic Roll, or Isover Ultimate Piano Plus in the
cavity (see Table 2 and 3). Airtightness is essential for
optimum sound insulation.
Partition duty – strength and robustnessThe duty ratings given in Table 2 and 3 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).
EXTREME duty The robustness of GypWall EXTREME is higher than most
severe duty criteria set out in BS5234: Part 2: 1992.
Additional structural performance and durability tests
above and beyond Severe Duty have been carried out to
reflect better the actual use in high traffic areas.
These tests include:
• Resistance to Deliberate Attack
Tests carried out included hard body impact to
destruction and a test designed to simulate an adult kicking
the partition.
• Resistance to Accidental Impact
A glancing blow test was developed to represent the
partition being hit at an angle by hospital trolleys etc.
• Resistance to Accidental Abrasion
In schools, hospitals etc abrasion can be caused deliberately
by keys, pens etc and accidentally by chair backs rubbing
against the wall causing scratch marks to appear due to
long term wear and tear. A scratch test and a hardness test
were developed to simulate abrasion.
In all the above tests, the impressive strength and surface
hardness of Gyproc Rigidur and the GypWall EXTREME system
were demonstrated.

DESIGN
Planning - key factors
Loads of up to 55kg can be hung directly from Gyproc
Rigidur. The position of some services and heavy fixtures
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.
Electrical
The installation of electrical services should be carried out
in accordance with all relevant legislation, regulations and
guidance. The cut-outs in the studs can be used for routing
electrical and other small services.
Where Gypframe AcouStuds are used, services are routed
through 50mm x 28mm ‘H’ shaped push-outs. Cables should
be protected by conduit, or other suitable precautions
taken to prevent abrasion when they pass through the
metal frame.
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 a 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.
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. The
maximum recommended heights in Tables 2 and 3 are
based on a limiting deflection of L/240 at a pressure of
200Pa. Information can be provided on specifications to suit
individual requirements. Contact the Technical Sales
Department for guidance.
Deflection heads
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 - 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 and ceiling channels must be securely fixed with a
row of fixings at 600mm maximum centres (148mm
channels require two rows of staggered fittings at 600mm
centres in each row). 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.
Door openings
The designer should consider the thickness tolerances of
the partition types in relation to the proposed door frame
detail. To satisfy BS5234 requirements for heavy and severe
duty, door framing should be specified in accordance with
Figure 5 or 6.
Exceptionally heavy doorsets may require additional
provision. Contact the Technical Sales Department if further
guidance is required.
Control joints
Control joints 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.
Fixtures
Due to the inherent strength of Gyproc Rigidur, some
fixtures can be applied directly to the board. Please refer to
the relevant Data Sheet for more information.
Ceramic tilesCeramic 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 - Ceramic tiling.
Board finishingPlease refer to Section - Finishing Coat Plasters,
Section - Jointing, and Section - Decorative
effects. Mineral based paints (e.g. lime, silicone) are not
suitable for use with Gyproc Rigidur.4.1

The fire resistance and sound insulation performances are for imperforate partitions, walls and ceilings incorporating boards with alljoints taped and filled, or skimmed according to Gypsum Industries’ recommendations. The quoted performances are achieved only ifGypsum Industries’ components are used throughout, and the Company’s fixing recommendations are strictly observed. Any variation in thespecifications should be checked with Gypsum Industries.

DESIGN
Planning - key factors
The position of services should be pre-determined and their
installation planned into the frame erection stage.
Cavity fire barriers
12.5mm Gyproc plasterboard, screw-fixed into the web of
perimeter channels or vertical studs, will provide a satisfactory
closure to flame or smoke. Alternatively 15mm Gyproc
FireLine or Glasroc F FIRECASE may be used.
Refer to section 3.9 - Cavity fire barriers.
Services
Penetrations
Penetrations of fire-resistant or sound-insulating constructions
for services need careful consideration to ensure that the
performance of the element is not downgraded and also that
the services themselves do not act as the mechanism of fire
spread or sound transmission.
Electrical
The installation of electrical services should be carried out in
accordance with BS 7671. The cut-outs in the studs can be
used for routing electrical and other small services (see
GypWall CLASSIC Construction details – 1). Switch boxes and
socket outlets can be supported from Gypframe 99 FC 50 or
150 FC 90 Fixing Channels fixed horizontally between studs,
or a high performance socket box detail where higher
acoustic performance is required.
Fixing floor and ceiling channels
Gypframe Floor & Ceiling Channels must be securely fixed with
a row of fixings at 600mm maximum centres. For 94mm
channels and above, 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.
Deflection heads
Partition head deflection designs may be necessary to
accommodate deflections in the supporting floor. Deflection
heads may also be required to the underside of roof
structures subjected to positive and negative pressures. See
Construction details – 1 - 2. Refer to section I (iii) – Principles of building acoustics.
OpeningsFireWall is used to divide space into fire compartments and, assuch, openings are generally not required. If openings are tobe specified they must be shown by fire test to maintain thefire performance of the wall.
Fixtures
Lightweight fixtures can be made directly to the partitions.
Medium weight fixtures can be made to Gypframe 99 FC 50
Fixing Channel. Heavyweight fixtures (to BS 5234), such as
wash basins and wall cupboards, can be fixed using Gypframe
150 FC 90 Fixing Channel.
Board finishing
Refer to section - Finishing systems and section -
decorative effects.

Key facts
BlastWall
BlastWall offers resistance to explosive devices, such as car
bombs, and can be specified in areas such as post rooms
and blast refuge areas. The system has been tested and
approved by some Government departments in the UK.
Specifications are determined on an individual basis
following consultation with Gypsum Industries and
specialist blast design consultants as to the performance
requirements. For detailed information on the BlastWall
system, please contact the Gypsum Industries Technical
Sales Department.
