2 C06 Floors and ceilings Introduction Floors and ceilings This section details floors and ceilings systems which cover a multitude of performance requirements in all sectors british-gypsum.com

3 Floors and ceilings British Gypsum offers a full range of specifications from simple plasterboard ceilings through to a range of gypsum-based, acoustic suspended ceilings and lay-in grid systems. They cover all building categories, including private and social housing, apartments, healthcare, educational facilities, recreational and industrial properties in both new-build and refurbishment and can satisfy the most demanding performance requirements. When specifying floor and ceiling solutions, 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 floors and ceilings system guide, below, allows you to simply select the performance categories of interest and identify the British Gypsum floor and ceiling systems which best satisfy your project requirements.

A building or part of a building of a type constructed before or around 99: a) using construction techniques that were coonly in use before 99; and b) with permeable components, in a way that promotes the dissipation of moisture from the building fabric. 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. The sound insulation values quoted in system performance tables are laboratory values and the practicalities of construction will mean that acoustic performances measured in the laboratory will be difficult to achieve on site 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 spaces requiring separation by sound insulating floors and ceilings abutting structural steelwork, consideration should be given to the potential loss of sound insulation performance through the steelwork C06.

18 C06 Floors and ceilings CasoLine mf CasoLine mf design Building design CasoLine mf comprises Gypframe MF7 Primary Support Channels and Gypframe MF Ceiling Sections which forms a suspended frame to which Gyproc, Gyptone, Rigitone and Glasroc boards can be fixed. Planning key factors The depth of the ceiling cavity is a minimum 00. Cavity fire barriers Where cavity fire barriers are required, these can be formed using Gyproc FireLine or Glasroc F multiboard screw-fixed to a simple frame. The framing should be fixed to the structure to avoid undue loading of the ceiling suspension grid or, alternatively, additional hangers should be incorporated to support the ceiling alongside the cavity fire barrier. Refer to C06. S07. P0 Cavity fire barriers. Relative humidity CasoLine mf ceilings lined with Gyproc, Gyptone, Rigitone or British Gypsum Specialist Boards are suitable for use under normal occupancy conditions. Buildings in which they are used should be dry, glazed and enclosed, with environmental conditions of no greater than 70% RH at 0 C to 0 C. For high humidity / high moisture conditions use Gyproc plasterboard mr variants or Glasroc F multiboard. Refer to C0. S0. P0 Robustness. Vapour control For areas other than where perforated Gyptone or Rigitone boards are used, a face layer of duplex grade plasterboard or two coats of Gyproc Drywall Sealer applied to the face of the lining will provide water vapour control. Acoustic performance Gyptone and Rigitone boards are perforated and designed to provide sound absorption when used in conjunction with an airspace behind the ceiling. Increased levels of sound absorption can be achieved by including insulation over the back of the ceiling. Where sound insulation room-to-room is required, sound attenuation D n,c,w of 9dB can be achieved by the inclusion of 00 Isover Spacesaver Ready-Cut over the back of the ceiling. Alternatively, other design considerations should be adopted such as extending adjoining partitions into the plenum void or installing a plenum barrier. Ceiling lift Changes to Building Regulations Approved Document L, airtightness requirements within dwellings, can lead to greater changes in air pressure when a door is opened. The ceiling is normally the lightest fixed element in the room, and therefore most likely to be affected by this change in pressure. This can cause the ceiling to lift, which may create a noise. Whilst this noise can be annoying to the occupier, it has no detrimental effect on the performance of the ceiling. The designer should consider incorporating a pressure release system to minimise the risk of ceiling lift. Where sufficient pressure relief cannot be designed in, it is recoended that the Gypframe MF Ceiling Section and the Gypframe MF7 Primary Support Channel should be screw-fixed together using two British Gypsum Wafer Head Jack-Point Screws at each intersection, particularly where non-perforated board linings are specified. Imposed loads Tables 6, 7 and 8 provide loading data for the suspension grid for Gyproc, Glasroc specialist, Gyptone and Rigitone boards respectively. Maximum loads will be reduced by % when Gypframe FEA Steel Angle is fixed directly to the soffit (modified loads are shown in brackets).

19 CasoLine mf design (continued) Suspension Gyproc, Glasroc specialist and Gyptone board linings Fixing points for suspending the metal grid are coonly required at 00 in each direction. Suitable fixing devices should be employed when fixing to the structure. The ceiling grid can be suspended from a concrete soffit using Gypframe MF Soffit Cleats and Gypframe MF8 Strap Hanger, or alternatively, Gypframe FEA Steel Angle. The latter provides a more robust suspension support, which restricts any flexing of the lining when pressure is applied from below. Gypframe FEA Steel Angle is therefore the preferred suspension option when a plaster finish is specified to Gyproc boards. If Gypframe FEA Steel Angle is used, it is recoended that it is fixed to the soffit via Gypframe MF Soffit Cleats. For single board solutions only, Gypframe FEA Steel Angle can be used to fix direct to the soffit. The angle should be cut along the spine with both flanges bent over. However, this will reduce the maximum loads that the grid is capable of supporting by %. Fixing Gypframe FEA Steel Angles direct is also not suitable if the ceiling is likely to deflect due to varying pressures and is not suitable for fixing to a sloping substrate. Gypframe Acoustic Hangers can be used to suspend the grid from timber joists to maximise the degree of acoustic isolation. In a comparative test a db improvement in airborne sound insulation and a 6dB improvement in impact sound insulation were achieved. Refer to table and construction detail 7, relating to double layer. Gyproc SoundBloc linings. With concrete floors the high mass of the construction means that high levels of acoustic performance can be achieved when the CasoLine mf ceiling is suspended by conventional means, i.e. Gypframe MF8 Strap Hangers or Gypframe FEA Steel Angle. Suspension Rigitone board linings Gypframe MF7 Primary Support Channels are fixed at 000. Fixing points to the structure for the Gypframe MF7 Primary Support Channels are required at 900. In addition to this, the Gypframe MF Ceiling Section should be installed at nominal 0. Refer to British Gypsum Ceilings Installation Guide for full details. Partition to suspended ceiling junction Where a GypWall metal stud partition is fixed to the framework of a CasoLine mf ceiling, in accordance with British Gypsum s installation instructions, its permissible maximum height is equal to that of where it is fixed direct to a structural soffit of the same height. In situations where a GypWall metal stud partition passes through a CasoLine mf ceiling, which is to both sides of the partition and appropriately fixed to both this partition and perimeter partitions / walls, consideration can be given to the lateral restraint provided by the ceiling when developing the partition specification. The relevant maximum height is the greater of the floor to CasoLine mf ceiling or ceiling to structural soffit height. Care should be taken during installation of tall partitions so as to not adversely affect their performance. Contact the British Gypsum Technical Advice Centre for further guidance. Services The plenum can be used to route all service requirements including ducting, pipework, electrical cables and conduit. All services should be independently supported from the building structure. Where light weight light fittings, access panels and similar components are incorporated as part of the design requirements, consideration must be given to maintaining the integrity of the ceiling to meet fire resistance and sound insulation requirements. Refer to tables 6, 7 or 8 for maximum recoended loads. Refer to profilex.co.uk for Gyproc Profilex Access Panels. Fixtures Fixings to the system should always be made into the metal grid or to supplementary framing. Some adjustment of the primary grid may be required to support heavier fixtures, refer to tables 6, 7 and 8. Where loads outside this range are anticipated, independent suspension should be provided from the structure. Control joints Gyproc Control Joints may be required in the ceiling to relieve stresses induced by expansion and contraction of the structure. It is recoended that they coincide with movement joints within the surrounding structure. Rigitone expansion joints Rigitone boards should be cut 0 short of the perimeter wall and should not be fixed to the perimeter channel. Refer to construction details -. Board finishing Refer to C08. S0. P0 Finishes. Additional care and attention should be exercised when jointing Gyptone and Rigitone boards so as not to fill the perforations and impair the acoustic performance of the finished ceiling. CasoLine mf Floors and ceilings C06 Handy hint When designing the CasoLine mf ceiling grid with a partition fixed to the underside, consideration should be given to ensure mf sections run parallel to the position, providing suitable restraint. This may result in additional Gypframe MF Ceiling Sections being required. Refer to British Gypsum Ceiling Installation Guide.
