2 C0 Partitions Introduction Partitions This section contains a full range of lightweight partition and wall systems for use in new and existing buildings. They cover all applications, from simple space division to high performance walls

3 Partitions British Gypsum offers a full range of lightweight partition and wall systems. Our systems are non-loadbearing and constructed using modern, drylining techniques. British Gypsum metal framed partitions and walls can be used in all types of new and existing buildings, including private and social housing, apartments, healthcare, educational facilities, recreational and industrial properties. They cover all applications, from simple space division, through to high performance walls designed to meet the most demanding fire resistance, sound insulation, impact and height requirements. Introduction Partitions C0 British Gypsum partition systems are constructed using lightweight materials, which can give rise to significant savings in structural design compared to masonry alternatives. Big benefits also include the speed of installation and reduction to overall build costs. Buildings need to evolve throughout their life to suit changing demands placed upon them. Our lightweight partition systems are easy to reconfigure with minimal impact to both building and occupants resulting in less disruption, optimising the transformation process.

4 C0 Partitions Introduction Partitions When specifying partitions, a number of performance characteristics are normally used to determine the required solution. Depending on the project or construction type, these performance parameters could be set by minimum regulatory standards, or a client or customer requirement for buildings that offer the highest standards of performance and comfort. Our quick-reference partition system guide, below, allows you to simply select the performance categories of interest and identify the British Gypsum partitions systems that best satisfy your project requirements.

Minimum solutions provide little or no margin of safety to allow for reduction in performance due to flanking transmission. Recommended solutions have greater potential to satisfy the requirements of Building regulations. Good practice specification guidance British Gypsum s systems are designed and tested to meet every performance requirement and are fully supported by our SpecSure lifetime system warranty. This means that when our systems are installed following our guidance they will achieve every performance claim we make, and if they don t then we ll put it right. To maximise the performance achieved on site, consider the following good practice specification guidance: Consider flanking transmission at the design stage and ensure construction detailing is specified to eliminate, or at least to minimise, any downgrading of the acoustic performance Small openings such as gaps, cracks or holes will conduct airborne sounds and can significantly reduce the sound insulation of a construction. For optimum sound insulation a construction must be airtight When designing the layout of rooms requiring separation by sound insulating walls abutting structural steelwork, consideration should be given to the potential loss of sound insulation performance through the steelwork Deflection heads, by definition, must be able to move and, therefore, achieving an airtight seal is very difficult without incorporating sophisticated components and techniques. Air leakage at the partition heads will have a detrimental effect on acoustic performance of any partition. Where acoustic performance is a key consideration, steps must be taken to minimise this loss of performance A common mistake made when designing a building is to specify a high performance element and then incorporate a lower performing element within it; for example, a door within a partition. Where the difference between insulation is relatively small (db or less), there needs to be a comparatively large area of the lower insulation element before the overall sound insulation is significantly affected. However, where there is a greater difference in sound insulation performance between the two elements, this would usually result in a greater reduction of overall sound insulation performance bgtechnical.enquiries@bpb.com C0.

26 C0 Partitions Non-loadbearing timber stud Non-loadbearing timber stud design Planning key factors The position of services and heavy fixtures should be pre-determined and their installation planned into the frame erection stage. If a plastered finish is specified, the thickness of the door or glazing frame must allow for the thickness of the plaster finish. To minimise the risk of cracking at the plasterboard joints, seasoned timber with a moisture content not exceeding that recommended in BS 68 should be used. The contractor should ensure that timber supports are accurately spaced, aligned, and levelled. Cavity fire barriers Cavity barriers may be required to satisfy the requirements of Building Regulations. Refer to C06. S0. P0 Cavity fire barriers. Services 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. Refer to C0. S0. P Service installations. Electrical Electrical and other small service runs can be routed within the timber stud cavity. The installation of electrical services should be carried out in accordance with BS 6. Switch boxes and socket outlets can be supported from timber stud noggings. Strength and robustness Timber should be aligned and level, and should meet the requirements of BS 68. The dimensions and assembly of timber supports should be sufficient to allow positive fixing of plasterboard without bounce or undue deflection. When the above fixing conditions cannot be met, a timber batten should be securely fixed to the side of the timber support to increase the bearing surface. Where boards are fixed at maximum centres in adverse conditions, the standard of lining can be affected. Adverse conditions can generally be described as conditions where high humidity occurs, principally in the cold, damp, autumn / winter period. They also refer to buildings under construction over this period, where both the structure and wet applications, such as plastering and screeding, are subject to slow drying conditions (refer to table ). Table Gyproc plasterboard or Glasroc F specialist board fixed direct to timber supports Board type Thickness mm Width mm Maximum recommended stud centres mm Gyproc WallBoard Gyproc FireLine Gyproc Plank Gyproc SoundBloc Glasroc F multiboard Partition junctions At a T junction, a ladder frame should be constructed between studs to provide fixing points for the abutting partition, and to support the lining (refer to construction detail ). The horizontal members of the frame should be at 600mm maximum centres. Fixing to super-dried timber It has been established by test that British Gypsum Drywall Screws are the preferred solution for fixing to standard softwood or superdried timber (approximately % moisture content). Nail popping Loosening of nails in timber can occur through timber shrinkage, or as a result of fixing boards to misaligned or twisted framing. To reduce the risks, boards should be fixed tight to framing members, using British Gypsum Drywall Screws. C0. S. P0 british-gypsum.com

27 Non-loadbearing timber stud design (continued) Fixtures Lightweight fixtures can be made directly to the partitions. Medium weight, or heavyweight fixtures such as cisterns, radiators or wash basins, can be made directly into the timber supports. Additional studs or timber noggings should be installed as appropriate. Board finishing Refer to C08. S0. P0 Finishes. Tiling Tiles up to kg/m can be applied to the surface of lightweight partition systems. Non-loadbearing timber stud Partitions Refer to C08. S0. P0 Tiling. C0 Important information Ensure British Gypsum Drywall Screws have a minimum of mm penetration into the timber frame. When using Gypframe RB Resilient Bar specifications, screw length selection is critical. Ensure the size of British Gypsum Drywall Screws selected to fix the lining to the Gypframe RB Resilient Bar do not penetrate the timber frame and therefore compromise the partition's acoustic performance bgtechnical.enquiries@bpb.com C0.

Timber framing is fixed to the perimeter, Door openings are formed by fixing full M&E services can be located within the abutments, and to frame any openings, height timber studs to each side, together partition cavity before the partition has using suitable fixings. Timber studs are with a timber head piece. Door casings are been boarded. Timber noggings are fixed fixed at specified centres. then fixed to the timber ground. Additional to support recessed switch boxes / socket framing is installed as required to support outlets. heavy fixtures. Non-loadbearing timber stud Partitions C0 Where Gypframe RB Resilient Bars are required, these are fixed horizontally to the timber studs to one or both sides as specified. Isover insulation can also be added to the partition cavity for increased acoustic performance. The perimeter of the partition is sealed on both sides with Gyproc Sealant. Gyproc plasterboards are screw-fixed to all timber supports, or to the Gypframe RB Resilient Bars with British Gypsum Drywall Screws. Horizontal board joints are backed with timber noggings or Gypframe RB Resilient Bars as required. The correct length of fixings must be used when installing the Gyproc board to the Gypframe RB Resiliant Bars to ensure that the acoustic performance is not compromised.
