GypWallTMQUIET SF

GypWall QUIET SF metal stud partition is a lightweight, non-

loadbearing, single-frame wall system. Subject to Local

Authority approval, it can be used as a sound resisting wall

between residential units, such as flats and apartments, to

meet the requirements of national Building Regulations.

The system can also be specified in commercial and

industrial buildings to meet a specific standard of sound

insulating performance.

The system consists of Gypframe studs and channels with

Gypframe RB1 Resilient Bar fixed to one or both sides.

Isover Acoustic Roll is included in the cavity and the

framework is lined on both sides with a range of Gyproc

plasterboards, including Gyproc SoundBloc, Gyproc

WallBoard and Gyproc Plank.

Gypframe Floor & Ceiling Channel is fixed to the floor and

soffit. Gypframe studs are fitted vertically to a friction fit

within the channel sections, and to abutments, to form the

framework. Studs are fitted so as to all face the same way.

Gypframe RB1 Resilient Bars are fixed transverse to the stud

framing. Bars are joined by nesting them together over a

stud, with the base flange fixed to the stud. The bars are

normally fixed with the base flange on the top side, with the

exception of the uppermost bar which is fixed base flange

down to provide board fixing at the wall perimeter.

Both layers of boards are fixed vertically to the Gypframe RB1

Resilient Bars with joints staggered. Where Gyproc Plank is

required as an inner layer fixed to resilient bar, it is fixed

vertically, with a minimum of two Gyproc DryWall Screws.

EnvironmentalGypWall QUIET SF partition is 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 protectionFor reaction to fire classifications for Gyproc and Glasrocboards please refer to Section .

Fire resistanceThe fire resistances given in Table 2 are for imperforate

partitions and have been tested in accordance with

BS 476: Part 8: 1972 or BS 476: Part 22: 1987 or assessments

based on these tests. Partitions were tested without timber

sole plates.

Sound insulationThe Rw ratings given in Table 2 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.

Partition duty – strength and robustnessThe duty ratings given in Table 2 have been calculated in

accordance with BS 5234: Parts 1 & 2: 1992. 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 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 Section - Introduction for general

considerations.

Maximum heightsThe 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.

Cavity barriersWhere a cavity barrier is required, a rock mineral wool strip

cut neatly to fit across the cavity forms a suitable closure.

Acoustic performanceThe partition achieves high levels of sound insulation by

virtue of the mechanical separation between the board

and the stud framing. It is important, therefore, that when

screw fixing boards, the screws do not contact the stud

framing and also that services, fixtures, etc, do not form a

bridge between the lining boards on each side of the

partition. If services must be fixed to the wall, surface

mounted fixings are less likely to affect acoustic

performance than services cut into the lining boards.

Fixing floor and ceiling channelsThe channels must be securely fixed to the surrounding

structure at 600mm maximum centres. 94mm and 148mm

Gypframe Floor and Ceiling Channels must be fixed with

two rows of staggered fixings, each row at 600mm centres,

and each fixing 25mm in from the flange. If necessary,

additional provision should be made to provide positive

fixing points.

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.

Deflection headsDeflection 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 main use of Gypframe Deep Flange (DC) and

Extra Deep Flange Floor (EDC) and Ceiling Channels is to

achieve deflection in GypWall QUIET SF. Please see Fig 7 or

alternatively contact the Technical Sales Department.

In most cases, a suspended ceiling will also assist in

minimising loss of performance.

3.1

DESIGN

Service penetrationsPenetrations of fire resistant constructions for services needcareful consideration to ensure that the integrity of theelement is not impaired and also that the services themselvesdo not act as the mechanism of fire spread. It is important touse only those services and their installations which havebeen shown by fire test to be able to maintain the integrity ofthe construction.

Installation of servicesThe installation of services should be carried out inaccordance with all available standards, guidelines andrecommendations. Cables should be protected by conduit,or other suitable precautions taken, to prevent abrasionwhen they pass through the metal frame. Switch boxesand socket outlets can be supported on brackets formedfrom Gypframe 99 FC 50 Fixing Channel fixed horizontallybetween the studs.

Door openingsAny openings will require very careful detailing if theacoustic performance of the partition is to be maintained.Specialist heavy acoustic doorsets may require additionalsupport.

FixturesLightweight fixtures can be made directly to the partitionlining. Medium weight fixtures can be made to Gypframe99 FC 50 Fixing Channel. Heavy fixtures should be made toindependent timber framing which is installed at the frameerecting stage. Medium and heavyweight fixings can only bemade when the lining boards are fixed directly to the studframing. The installation of fixings may downgrade theacoustic performance of the wall.

Control jointsControl joints may be required in the partition to relievestresses induced by expansion and contraction of thestructure. The location of control joints is at the discretion ofthe specifier. It is recommended that they coincide withmovement joints within the surrounding structure.

Ceramic tilingCeramic tiles up to 12.5mm thick with a maximum weight of32kg/m2 can be applied using thin bed adhesives (usually3mm thick). Stud centres will normally require closing down.Please refer to Section - Ceramic tiling.

FinishingPlease refer to Section - Jointing, Section- Finishing Coat Plasters and Section - Decorative effects.

EstimatingThe estimated construction time is 1.5 – 2m2 / man hour(double layer partition) ready for finishing.
