book 3_jan10b:a01 Introduction v2.qxd 15/04/2010 17:35 Page 88 GypWall TM 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.

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 DUTY Adjacent space only accessible to persons with high incentive to exercise care. Small chance of accidents occurring or of misuse. Domestic accommodation MEDIUM DUTY Adjacent space moderately used, primarily by persons with some incentive to exercise care. Some chances of accidents occurring and of misuse. Office accommodation HEAVY DUTY Adjacent space frequently used by the public and others with little incentive to exercise care. Chances of accidents occuring and of misuse. Public circulation areas. SEVERE 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. Industrial areas. Adjacent space intensively used by Major circulation the public and others with little areas. incentive to exercise care. Prone to vandalism and abnormally rough use. Heavy industrial areas. 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. book 3_jan10b:a01 Introduction v2.qxd 15/04/2010 17:35 Page 93 E [email protected] PERFORMANCE 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. 3.2 101 book 3_jan10b:a01 Introduction v2.qxd 15/04/2010 17:35 Page 102 General purpose metal stud partition system GypWall™ www.gyproc.ie 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. 3.2 102 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. book 3_jan10b:a01 Introduction v2.qxd 15/04/2010 17:35 Page 103 E [email protected] Fig 1 - Service cut-outs in Gypframe ‘C’ studs (all dimensions in mm) Centres at 600mm thereafter 1500 30 38 38 38 75 75 75 75 General purpose metal stud partition system F 00353 1 623 7054 GypWall™ T 00353 1 629 8400 900 300 48mm Stud 60mm & 70mm Stud 92mm Stud 146mm Stud CONSTRUCTION DETAILS Fig 2 - Head and base Fig 3 - Wall junction - stud to wall and stop end detail 3.2 Gyproc Sealant (for optimum acoustic performance) 103 book 3_jan10b:a01 Introduction v2.qxd 15/04/2010 17:35 Page 104 General purpose metal stud partition system GypWall™ www.gyproc.ie CONSTRUCTION DETAILS - CONTINUED Fig 4 - ‘T’ junction detail when acoustic performance is a key consideration - helps to reduce flanking transmission Fig 5 - Wall junction (Gyproc Thermal laminate wall lining) Gypframe GA5 Internal Fixing Angle Fig 7 - Gypframe 99 FC 50 Fixing Channel - Short legs flattened at stud positions.
