GypWallTM

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 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.

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’ .

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 protectionFor reaction to fire classifications for Gyproc and Glasrocboards please refer to Section .

Fire resistanceThe 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 insulationThe 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.

2.1

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 finishedaccording to Gypsum Industries’ recommendations.

The quoted performances are achieved only if Gypsum Industries components are used and the Company’s fixing recommendations are strictlyobserved. 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).

Gypframe studs are available in bespoke lengths on request from Gypsum Industries to satisfy large projects. Please contact Gyprocat 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 toadjoining structures.

CONSTRUCTION DETAILS

Partition duty - strength and robustnessThe 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

Grade Category of duty Examples

LIGHT Adjacent space only accessible to DomesticDUTY persons with high incentive to accommodation

exercise care. Small chance of accidents occurring or of misuse.

MEDIUM Adjacent space moderately used, OfficeDUTY primarily by persons with some accommodation

incentive to exercise care. Somechances of accidents occurring and of misuse.

HEAVY Adjacent space frequently used by Public circulationDUTY the public and others with little areas.

Please refer to Section - Introduction for general

considerations.

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 in the event of fire.

Maximum heightsThe 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 barriersPerimeter cavity barrier

The Gypframe Floor and Ceiling Channels can be

considered satisfactory closures to flame and smoke,

abutting ends of channel may, however, require fire-

stopping. 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 for further information.

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.

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.

In most situations the services will be installed bycontractors other than the dry lining contractor. It isimportant, therefore, that all relevant contractors shouldbe advised as to where and how their service penetrationsshould be made and maintained.

The necessity to independently support services will dependon their size and weight. Please contact the Technical SalesDepartment for guidance.

Dampers / ductsWhen designing for the installation of fire dampers andassociated ductwork through a GypWall partition,consideration should be given to the size and weight ofthe damper. This will determine whether it can besupported directly from the partition or needs to beindependently supported from the structure. Test evidenceand advice is available from the Technical Sales Departmentto cover a number of situations including direct supportfrom the partition and also where the damper is offsetfrom it. 1 Specific advice on the fixing of the dampershould be obtained from the damper manufacturer. Pleaserefer to CONSTRUCTION DETAILS, Figs 20 and 21.

Wind loadingGypWall partitions are non-loadbearing but can accept adegree of wind loading, for example when used inbuildings with large or multiple external doors.Information can be provided on specifications to suitindividual requirements, including the provision ofdeflection heads.

Deflection headsPartition head deflection designs may be necessary toaccommodate dead load or live load deflections in thesupporting floor and/or roof construction and differentialfloor loadings. This can be in the form of live loads onintermediate floors creating a + condition or a simple minusdeflection for dead loads on the structural floors.Deflection heads may also be required to the underside ofroof structures subjected to positive and negative pressures.

GypWall partitions can incorporate head deflection designsto accommodate structural deflection (please see Figs 16 to19). Where greater deflection needs to be accommodated,please contact the Technical Sales Department for guidance.

Installation of servicesThe 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.

FixturesLightweight 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 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.

EstimatingThe estimated construction time is 2 - 3m2 / hour (single

layer partition) or 1.5 - 2m2 / hour (double layer partition)

ready for finishing.

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 - 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 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 openingsThe 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 jointsControl 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.
