P02 – P08 Floors and ceilings introduction Introduction Floors and ceilings C06 Floors and ceilings This section details floors and ceilings systems which cover a multitude of performance requirements in all sectors british-gypsum.com Introduction 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. Floors and ceilings 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. 1 2 C06 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 1919: a) using construction techniques that were commonly in use before 1919; and b) with permeable components, in a way that promotes the dissipation of moisture from the building fabric. 1 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 C06. S01. P03 —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 british-gypsum.com Introduction Gyptone performance Table 3 – Sound absorption data for Gyptone boards Sound absorption coefficient αp Practical absorption coefficient αp QUATTRO 41 Gyptone quattro 41 (plenum depth 187mm) 1.0 0.8 Practical absorption coefficient αp 0.6 0.4 0.2 125 250 500 1k 2k 4k αW AC1 NRC2 0.50 0.70 0.80 0.70 0.60 0.55 0.65 C 0.70 0.0 125 250 500 1000 2000 4000 Frequency (Hz) System reference Practical absorption coefficient αp Sound absorption coefficient αp Gyptone quattro 42 (plenum depth 50mm)3 1.0 Practical absorption coefficient αp 0.8 0.6 0.4 0.2 125 250 500 1k 2k 4k αW AC1 NRC2 0.20 0.40 0.60 0.60 0.45 0.40 0.50 D 0.55 125 250 500 1000 2000 C06 0.0 4000 Frequency (Hz) System reference C10A110 Sound absorption coefficient αp Practical absorption coefficient αp QUATTRO 46 Gyptone quattro 46 (plenum depth 400mm) Gyptone quattro 46 (plenum depth 400mm plus 100mm Isover Spacesaver Ready-Cut) 1.0 0.8 0.6 0.4 Practical absorption coefficient αp 0.2 0.0 125 250 500 1000 2000 Frequency (Hz) System reference C10A014 C10A015 125 250 500 1k 2k 4k αW AC1 NRC2 0.65 0.60 0.55 0.45 0.40 0.35 0.45(L) D 0.50 0.60 0.60 0.65 0.55 0.45 0.40 0.50(L) D 0.55 4000 AC - Absorption Class.

Any variation in the specifications should be checked with British Gypsum. C06. S07. P03 british-gypsum.com Planning – key factors Important information The maximum distance between barriers must be appropriate to the location of each cavity. Also, due consideration must be given to the class of surface exposed within the cavity. It is also important that smoke and flames are restricted from passing from any cavity in a building element directly into a room or another cavity. Therefore, a cavity must be closed by a cavity barrier at every junction with another cavity. Any cavity contained within an element is also required to be closed by a cavity barrier around the perimeter of any opening through the element. The closure of cavities may already be provided by the construction itself, e.g. where a British Gypsum partition system prevents the continuation of cavities at a ‘T’ junction. Fixings through the cavity barrier framework into the structural soffit must be capable of supporting the weight of the entire cavity barrier construction. British Gypsum ceiling solutions are not intended to provide any support to the cavity barrier. Fire stopping Smoke and flames must also be restricted from by-passing any building elements that are required to have fire resistance. Any cavity crossing the edges or ends of a fire resistant element should have a cavity barrier provided in the same plane as the element, refer to construction details 3 - 5. There are certain exceptions to this requirement, such as cavities in floors and roofs where the ceilings provide a minimum of 30 minutes fire resistance in addition A cavity barrier must be tightly fitted to a rigid construction, or, if it abuts against slates, tiles, corrugated sheeting, or other construction to which it cannot be so fitted, then it must be suitably fire-stopped at the junction. Refer to construction details 1 - 2, which show fire-stopping solutions using stone mineral wool. to satisfying other stipulated requirements. fire-stopped using suitable materials, shown by test to maintain the fire resistance within that construction. Any services running through a fire cavity barrier should be C06 [email protected] Floors and ceilings Cavity barriers must maintain their performance during the life of a building, taking account of any possible building movement due to subsidence, shrinkage, or thermal change. In addition, the possible failure of its fixings or adjacent construction in the event of a fire, and the collapse in a fire of any permitted services penetrating the cavity barrier, should be considered. 0844 800 1991 Cavity fire barriers Cavity fire barriers design C06.
