4 C09 Sound absorbing solutions Introduction Sound absorbing solutions Areas to consider when specifying Acoustics A suspended ceiling can provide two levels of acoustic performance; sound insulation, preventing the passage of sound into the room from an external source, and sound absorption, which is the control of undesirable sound within the room, in the form of reverberation. Ceiling systems incorporating products such as Gyproc SoundBloc provide the greatest level of sound insulation, while the Gyptone, Rigitone or Eurocoustic ranges provide excellent sound absorption performance for reverberation control. Aesthetics The ceiling provides a large blank canvas which can form part of the overall interior design scheme. Patterns, colours and shape can all be easily incorporated using products such as Gyptone or Rigitone. A lower key, minimalist appearance can be achieved with the clean, white finish of Gyprex or Eurocoustic systems. Air quality Historically, the role of a suspended ceiling has been limited to passive performance in terms of aesthetics, acoustics and fire resistance. With our VOC-absorbing ACTIVair technology now available as standard in all Gyptone and Rigitone products, the ceiling can now take on a more active functional role within the room. It actively improves the indoor air quality and provides the associated benefits to the occupants in the space below. Refer to C0. S0. P9 Indoor air quality. Accessibility Whatever type of ceiling is designed (table ), access to the cavity above the ceiling will inevitably be required. whether this is for inspection, maintenance or repair of HVAC and similar services. A seamless system such as CasoLine mf can accommodate access points in the form of Profilex or Gyptone access hatches, whilst lay-in grid ceilings have the advantage of allowing access at virtually any point across the ceiling. Table Ceiling system combinations Demountable systems Gyprex tiles T5 T Plank Types of ceiling Demountable A traditional demountable ceiling consists of individual ceiling tiles which are laid into a metal grid. More recent innovations of the traditional lay-in grid ceiling include the CasoLine quick-lock-grid Corridor System. The plank system can be used to provide totally clear, unobstructed access to M&E services in commercial buildings. Lay-in ceilings are generally simple to install, easy to maintain and can be dismantled, repositioned or even reused. Seamless Systems such as CasoLine mf or GypLyner universal ceilings provide a smooth, seamless monolithic ceiling. These types of ceiling can be used to achieve high levels of sound insulation, absorption, or both. These systems provide a large degree of flexibility and can be installed horizontally, sloped, vertically or - using CasoLine curve - giving a contoured shape. Cleanability Commercial ceilings are subject to a diverse range of cleaning regimes. A typical sports hall, for example, may require little or no cleaning during its working life. A hospital ceiling, on the other hand, needs to cope with the frequent and/or aggressive cleaning regimes required in clinical areas. Ceiling systems such as Gyprex bio provide a wipeable vinyl surface with an integral biocide, preventing the growth of fungi and bacteria, including MRSA, E. coli O57 and Salmonella. Additional Information Our Gyptone range offers the highest level of accessibility to the ceiling cavity. Gyptone Hatch, Gyptone Plank and the Gyptone TRAP system are ideally suited to where regular or unrestricted access to the cavity is required and can be used either as a stand-alone solution or in conjunction with another Gyptone ceiling.

12 C09 Sound absorbing solutions CasoLine mf CasoLine mf design Building design CasoLine mf comprises Gypframe MF7 Primary Support Channels and Gypframe MF5 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 00mm. Relative humidity CasoLine mf ceilings lined with Gyproc, Gyptone, Rigitone or Glasroc 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. 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 00mm 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. Refer to C09. S0. P0 Sound absorbing solutions introduction, tables and. Thermal performance Isover insulation can be laid over the suspension grid to provide the required standard of thermal insulation. Contact the British Gypsum Technical Advice Centre for further guidance. 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 recommended that the Gypframe MF5 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 and provide loading data for the suspension grid for Gyproc, Glasroc specialist, Gyptone and Rigitone boards respectively. Maximum loads will be reduced by 5% when Gypframe FEA Steel Angle is fixed directly to the soffit (modified loads are shown in brackets).

Gypframe MF7 Primary Support Channel. Suspension Gyproc, Glasroc specialist and Gyptone board linings Fixing points for suspending the metal grid are required at 00mm centres 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 recommended 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 5%. 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. C09. S0. P0 british-gypsum.com

13 CasoLine mf design (continued) Suspension Rigitone board linings Gypframe MF7 Primary Support Channels are fixed at 000mm centres. Fixing points to the structure for the Gypframe MF7 Primary Support Channels are required at 900mm centres. In addition to this, the Gypframe MF5 Ceiling Section should be installed at nominal 0mm centres. 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. Where 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 or for maximum recommended loads. 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 and. 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 recommended that they coincide with movement joints within the surrounding structure. Rigitone expansion joints Rigitone boards should be cut 0mm short of the perimeter wall and should not be fixed to the perimeter channel. Refer to construction details 9-0. Board finishing Refer to C08. S0. P0 Jointing. 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.

The ceilings boards are screw fixed to the underside of the Gypframe GL Channels. This section refers to GypLyner universal ceiling installation only. For guidance relating to wall lining installations refer to C07. S0. P0 GypLyner universal. Planning key factors The depth of the ceiling cavity is determined by the positioning of the fixing brackets. For concrete soffits the fixing brackets allow sufficient adjustment for levelling the ceiling. When using Gypframe GL Brackets, allow for a stand-off of 5mm - 75mm plus the lining thickness. When using Gypframe GL9 Brackets, allow for a stand-off of 5mm - 5mm plus the lining thickness. When using Gypframe GL Brackets, allow for a stand-off of 5mm - 75mm plus the lining thickness. When fixing to timber joists using Gypframe GL5 or GL6 Timber Connectors, allow for a maximum cavity depth of 5mm and 0mm respectively, measured from the bottom of the joists to the underside of the lining. Acoustic performance Handy hint A maximum stand-off of 75mm can be accommodated by the GypLyner universal system. For increased plenum depths. Refer to C09. S0. P0 CasoLine mf. 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 00mm 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. Refer to C09. S0. P0 Sound absorbing solutions introduction, table and. Fixing to the structure Gypframe GL8 Track is suitably fixed to the perimeter at 600mm centres. Gypframe GL GypLyner Anchors are suitable for fixing brackets to solid concrete or soffits. Refer to table below for fixing centres: Table Maximum component centres (mm) Lining GypLyner GL GypLyner GL GypLyner GL5 or GL9 or GL or GL6 Rigitone board Gyptone board Services The cavity above the metal framework facilitates the incorporation of services. Pipes and conduits should be fixed in position before installing the framing. Where 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. Cables, pipework and conduits should be independently supported from the building structure. Refer to C0. S0. P Service installations. Fixtures Fixtures with a maximum weight of kg, eg. single lights, can be fixed into the channels. For other fixtures, independent suspension should be provided from the structure. Board finishing Refer to C08. S0. P0 Jointing. 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.

48 C09 Sound absorbing solutions CasoLine quick-lock grid t CasoLine quick-lock grid t design Building design CasoLine quick-lock grid t is mm wide metal frame grid comprising CasoLine quick-lock grid /8 Mains Tees, /8 Cross Tees and Wall Angles into which Eurocoustic, Gyptone or Gyprex tiles can be installed. Planning key factors Ceilings should be set out from the centre to give balanced widths of tiles at the perimeter. Two grid layouts are possible, depending upon the choice of ceiling tile. Refer to construction detail for configuration options. Designers and installers should take due regard of BS EN 96: 0, Suspended Ceiling Requirements and test methods. Relative humidity (RH) The grid is suitable for use in heated occupied buildings in conditions up to 90% relative humidity (RH90). Gyprex tiles are suitable up to RH90 and Gyptone tiles up to RH70. Cavity fire barriers Where cavity fire barriers are required, they 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. The bottom of the framework should be fixed to the ceiling grid. Refer to C06. S07. P0 Cavity fire barriers. Fire-stopping It is necessary to provide suitable non-combustible fire-stopping material at the junction of a cavity fire barrier with the structural perimeter and the ceiling. Fire-stopping must also be provided around any service penetrations through the cavity fire barrier. Water vapour control Gyprex tiles have a water vapour resistance factor of 600. Whilst the vinyl surface can provide an effective vapour control layer, it may be necessary to complete the integrity where the boards abut metal grid sections. This is achieved by sealing with continuous beads of water vapour resistant sealant, which should be applied to the back of the metal sections prior to inserting the tiles. Care should be taken to ensure that the sealant does not damage the vinyl surface of the tiles. Other precautions, such as cavity ventilation, may be necessary to reduce the risk of interstitial condensation. Table 5 Self-weight of tiles in CasoLine quick-lock grid t - mm grid systems Edge detail Self-weight of tiles kg/m Fixtures Gyptone base and Gyprex Gyptone base and Gyprex will support a point load of up to kg / tile for maximum mm deflection. This will normally allow items such as spotlights and down-lighters to be installed without the need for a support pattress. A support pattress should, however, be installed where the prevailing environmental conditions exceed 5 C and RH70, or where the size of the cut-out required is greater than 50mm diameter or 50mm square. Apertures for spotlights and down-lighters can be cut into these ceiling tiles using a circular tank cutter on a power drill or using a pad saw. Gyptone perforated and Eurocoustic Gyptone perforated tiles and Eurocoustic tiles should not be used to support fixtures, however this can be accommodated with the use of a pattress as described above. Services The ceiling void above the suspension grid can be used to route all service requirements including ducting, pipework, electrical cables, and conduits. Ducting, ventilation units, etc, must be independently supported from the structure. Maintenance Ceiling tiles can be cleaned using a damp cloth or soft brush. Most standard mild detergents can be used. Tiles other than Gyprex can be re-decorated if required using a suitable emulsion paint and a short-haired brush or roller (spray painting will impair sound absorption). Gyptone tiles with ACTIVair Though we don t notice them, impurities, such as Volatile Organic Compounds (VOCs) including formaldehyde, are often present in the air we breathe - emitted from furniture, carpets and building materials. Long-term exposure to these can potentially cause health problems and reduce general wellbeing. Studies have shown that clean air, can speed up patient recovery in hospitals, reduce absence at work, and increase pupils concentration at school. ACTIVair is our latest technology designed specifically to convert formaldehyde emissions into non-harmful inert compounds. Tests show that ACTIVair decomposes 70% of the formaldehyde in a controlled test environment. This clever technology continues to work for over 50 years, and whilst alternative solutions absorb formaldehyde, they don t decompose them like ACTIVair, risking re-emission at a later date.
