Customised Design SolutionsThe systems detailed in this

book should cover most common

situations where noise control is

required. However, for projects

where specific performance is

necessary, GIB® Technical Services

can assist you to develop customised

noise control solutions. Simply

contact us through the GIB® Helpline

on 0800 100 442.

Beware of SubstitutionThe performance of noise control

systems is very sensitive to design

detailing and construction practices. All

GIB® Noise Control Systems have been

developed specifically for New Zealand

conditions and independently tested or

assessed to ensure the required level of

performance is achieved. Therefore, it is

important to use only GIB® branded

components where specified and closely

follow the specified design details and

construction practices, to ensure the required

level of noise control is achieved on site.

For further information, please don’t hesitate to

call our GIB® Helpline 0800 100 442.

This publication supersedes the

following publication:GIB® Noise Control

Systems, 2000.

The New Zealand Building Code requirements for noise

control represent the minimum allowable standard, and in

many cases may fall far short of what people find acceptable

in today’s modern urban environment.

People now rate noise as one of their biggest concerns

in homes, schools, the workplace and especially in high

density and mixed land use areas.

Research shows that many apartment and townhouse

owners can be dissatisfied with the level of noise control

in their units, provided by the code.

Effective (above the code) noise control in a quality

development should have a significant positive effect

on value, rental fees, return on investment and

resale potential.

This technical literature provides noise control systems and design advice for designers, specifiers, and builders. This information can be used throughout the building design process to help determine the level of acoustic comfort required and select systems to achieve this.

DESIGN ADVICEDesign guidelines are provided for several building types (e.g. Hotels, Retirement, Intertenancy, etc). These can be usedin conjunction with acoustic specialists to help determine appropriate acoustic comfort levels and select appropriate wall and ceiling systems.

Advice is provided on where and how to treat rooms, junctions, penetrations and on-site testing.

NOISE CONTROL SYSTEMSWinstone Wallboards Ltd offers a wide range of GIB® wall and floor/ceiling noise control systems. Recommended systems appear for each building type, and a full list of systems is provided on pages 2-4.

GIB® Noise Control Systems have been extensively independently tested and evaluated and can be depended on to perform. They represent the state of the art in noise control materials and cost effective design. Noise control can be counter intuitive (e.g. thicker material can degrade performance) and systems are sensitive to component substitution.

The Building Noise Control Design Process MARCH 2006


Establish legal (from NZBC and district plan) and organisational (e.g. health and education board) requirements.

Identify noise sources (how loud, sound paths) including external noise, plant rooms, services etc.

Decide on the desired level of acoustic comfort (design acoustic comfort) that reflects the quality of the building and matches occupant/owner expectations.

Determine building element performance (STC/IIC) required to deliver the desired level of acoustic comfort and meet legal requirements.

Design for flanking paths (e.g. window to window, ceiling plenum, across floor, load bearing walls, services etc) and optimise building layout for noise control.

Select appropriate building elements (walls, floor-ceilings, doors and windows).

Implement quality control and compliance plan (check lists, expert inspection, site tests).

When and Where to Specify Noise Control MARCH 2006

WHEN TO SPECIFY• Specify after determining the design acoustic comfort, any legal requirements, and nature of expected noise sources• Specify early in the planning process to integrate acoustic requirements with room layout, junctions, building services, and other

building code and functional requirements• The designer’s preliminary task is to determine legislation applicable to each room or space and the design acoustic comfort level.• The next task is to consider the nature of expected noise sources (e.g. level, duration, time of occurrence)• From these inputs and the desired outcome the amount of noise control can be determined.

Noise sources + noise control measures = Legal requirements and design acoustic comfort

Determining the acoustic comfort design level requires balancing several factors such as budget, owner and occupant expectations, building code and district plans, organisational standards, and the intended function of a room or space. It can impact on junction details, building service placement and containment, room layout, construction types, and quality assurance programmes.

It is therefore recommended to use an acoustic specialist early in the design process.

Noise Control Does Not Mean SilenceIt is important to manage occupant / owner expectations. Noise control does not imply silence. The picture below shows this diagrammatically: noise control has reduced sound transmission, not eliminated it.

When and Where to Specify Noise Control MARCH 2006


WHAT TO SPECIFYThe building elementOnce the required level of noise control has been determined (STC or IIC), a system may be chosen. Factors to consider include:• Footprint or depth – systems can have different total thickness affecting floor space or available height• Impact through walls – cupboard doors and knocks on walls are impact sounds. These are best reduced by walls with acoustic

isolation (e.g. double frames).

Building connectionsIt is usually not sufficient to simply specify a building element. Also consider:• Junction details: sound travels in all directions – sideways, diagonally, as well as up and down. Suitable junction details must be

used to minimise flanking sound• Penetration details• Services (e.g. HVAC, lifts, plumbing)• Doors and glazing• Where continuous timber flooring occurs performance of wall systems is expected to degrade by up to 3 STC points.

Site performance and sound flanking pathsThe systems tested in the laboratory are constructed to accurately reflect installation on site. However, in practical applications the NZBC permits a 5 STC point variation from the tested value, to take account of flanking paths.Provided the published specifications are followed precisely, the laboratory IIC values will be achieved on site within the margin of error of the test method (+/- 4IIC).The transmission of intrusive noise from one space to another within a building is dependant on the sound transmission performance of the surrounding structure being the same or greater than the performance of the GIB® Noise Control System.Sound flanking paths via the surrounding structure must be avoided in order to achieve the published system performance.

What framing system to choose?This book contains a number of options for constructing intertenancy walls using timber or metal framing. These include single frames, single frames with a resilient rail on one side, staggered studs, and double frames.Although all systems achieved the published STC rating in a laboratory, a similar performance on site is often much harder to attain.• Single stud systems may be used in situations where the wall is installed between concrete floors and where there are no

intersecting walls, penetrations, or any fittings (eg kitchen joinery) connected to the wall. Minor deviations from the specification or inaccuracies in construction can result in a significant performance loss. Single stud systems are not generally recommended for intertenancy construction

• Resilient single steel stud systems (GIB® Rondo® Quiet Stud®) and resilient rail systems are a little less prone to site variations. However, extreme care must be taken not to bridge the gap between the linings and the framing on the resilient rail side. This can happen by accidentally screw fixing through the rail into the stud, the use of packers to connect joinery, mounting of electrical switch boxes, etc. Flanking paths can also be easily created at wall and floor ceiling junctions

• Staggered stud and double stud systems deliver by far the best on-site performance and are generally recommended for intertenancy construction. When connections between the frames are required for fire stability or structural reasons, these must be designed with care. Structural connections, such as continuous timber flooring, can reduce the STC rating of double stud intertenancy walls by up to 5 STC points.

Floor joist depthThe tested floor joist depth was 240mm. The STC and IIC values remain unchanged when the joists are reduced to 150mm.

AppliancesWashing machines, wall-mounted driers and speaker boxes, TVs, and even some light switches, transmit sound vibration into the structure. It is easy for this structure-borne sound to then be transmitted to adjacent occupancies.

Following these simple rules will minimise the risk of noise problems.• Do not mount appliances on intertenancy walls• Locate driers and the like on external walls or other non-critical walls. When positioned on the floor, place on resilient

mountings• Do not mount TVs or speaker boxes on critical intertenancy walls or on partition walls within the unit that separate living areas,

such as the lounge, from quiet zones such as a study or a bedroom• Never mount electrical outlets back-to-back.

Sound control infillUnless otherwise noted GIB® Noise Control Systems were tested with R1.8 (75mm) Pink® Batts® glass wool insulation with a density of 9.5kg/m2. When substitution of cavity infill takes place independent verification must be obtained to confirm that the noise control performance of the system will be maintained.

Noise Control for Intertenancy MARCH 2006

INTRODUCTIONWhere separate occupancies adjoin, noise is a fundamental consideration. Designers need to select an acoustic comfort level aligned with occupant expectations. Besides impacting the sense of quality, noise control reduces annoyance from neighbours and improves the sense of privacy.Hence, while the New Zealand Building Code (NZBC) sets a legal minimum, it is common to set higher standards as a point of differentiation and to align with the quality of the building.

REGULATIONSThe NZBC (Clause G6) sets a legal minimum noise control performance between adjoining occupancies. The code provides a minimum level of noise protection for occupants. Occupants often have higher expectations. While guaranteed silence between adjoining units is not possible, it is possible to considerably improve on the provisions of the NZBC.

SETTING THE DESIGN ACOUSTIC COMFORT LEVELAn important design question is which level of acoustic comfort should be considered. The table below links comfort to STC and IIC ratings. The table provides a guide to choose GIB® Noise Control Systems that best meet your needs for that level of comfort.The information is derived from European studies and standards and is provided for general guidance.

ACOUSTIC COMFORT RATING COMMENT

Minimum:50% of occupants satisfied

STC 55 / FSTC 50 IIC 55 / FIIC 50 This is the NZBC minimum requirement.

Satisfaction:About 80% of occupants satisfied

STC 60 / FSTC 55IIC 60 / FIIC 55 dB(A) 30 in living areas

It is necessary to identify and consider all potential sound sources e.g. services and external noise. Typically these are designed for in terms of the sound level in living areas, in dB(A).

Superior performance: sometimes disturbed by noise

STC 65 / FSTC 60IIC 65 / FIIC 60

At higher comfort levels the ability of a construction to reduce low frequency sounds, for example home theatre and loud music is particularly important.

Excellent:Seldom disturbed by noise

STC 65+/ FSTC 65IIC 65+ / FIIC 65 dB(A) 20 in living areas Consideration of low frequency performance

FLOOR/CEILING SYSTEMSGIB® Noise Control floor-ceiling systems offer excellent performance for both airborne and impact sound. However, although code compliance can be easily achieved with good quality underlay beneath carpet, code compliance for impact sound is much more difficult to achieve on hard floor surfaces.

GIB® Noise Control systems for hard floor surfaces such as timber strip flooring, vinyl and ceramic tiles are available with the inclusion of GIB Sound Barrier® floor overlay. These systems are published in the technical brochure entitled “GIB Sound Barrier®”.

Although there appears little difference in performance between some floor-ceiling systems published in this book, the use of GIB Quiet Clip® in systems GBDFA 60c, GBDFA 30a and GBDFA 30d offers superior low frequency performance of up to 8 dB improved attenuation in the frequency range 50Hz to 125Hz. As footfall, and other common domestic sound is often in this range the GIB Quiet Clip® offers significant advantage over direct fix systems.

MINIMISE RISKA quality control programme is recommended to help minimise risk from variations, and to indicate noise control performance early on. Liaise with local authorities to determine the requirements for compliance (e.g. acoustic engineers approval, lab test certificate, or a specific set of onsite tests). The NZBC Clause G6 requires that habitable spaces in household units are protected from other occupancies using wall and floor/ceiling elements with a laboratory tested performance of STC 55 (walls and floors) and IIC 55 (floors only).

CONCRETE AND MASONRY STRUCTURESThe performance of pre-cast concrete walls more than 150mm thick and solid filled masonry 200mm thick is very sensitive to construction practices, detailing and concrete density. Although these walls can achieve STC 55, the sound attenuation is greatly enhanced when resilient mounts and/or battens are installed on at least one side. These additions can be counter intuitive unless a minimum cavity of 45mm is created and filled with sound control infill prior to lining. Polystyrene is not a suitable infill. For further assistance with noise control ratings for concrete and masonry structures please call the GIB® Helpline 0800 100 442.

Noise Control Systems for Offices MARCH 2006


INTRODUCTIONNoise control plays an important role in office comfort, productivity and privacy/confidentiality. Studies show that a positive environment has a positive effect on business. Attention needs to be given to noise control, room acoustics, and services.

Open plan offices require a degree of privacy which is achieved to some extent by masking sounds.

Senior managers expect more noise control and require it for confidentiality. Seminar and meeting rooms, and walls between tenants need to protect the amenity value of users. Wall penetrating ceilings will provide a higher level of performance.

The table below summarises general noise control recommendations for offices.

SPACE DESIGN GUIDE

Open plan office • Workstation partitions minimum 1.5m high• Ceiling tile absorption NRC 0.8• Background PNC 38-43 dB continuous• Total floor area no less than 10m2/person

Lawyer-to-Lawyer Wall and floor STC 45-50. Carpet on any floor above office. Solid core doors with seals.

Senior Manager Wall and floor STC 40-45. Carpet on any floor above office. Solid core doors with seals.

Meeting and seminar rooms

Walls and ceiling STC 40-45. Carpet on any floor above room. Solid core doors with seals. Acoustic ceiling tiles with absorption NRC 0.55 (STC 50 for meeting rooms surrounded by constant high background noise).

Bathrooms; walls with sinks or cupboards

STC 50 walls adjacent to noise sensitive area like reception, meeting rooms or offices; isolate plumbing from frames with resilient mounts or use double or staggered frames. Or use a buffer (e.g. a storage room between bathroom and office).

Reception Walls and floors to protect from noisy areas (e.g. as for bathrooms and kitchens etc); Acoustic ceiling tiles with absorption NRC 0.8 around receptionist only.

Between office tenancies

Minimum STC 55 (Dependant on adjoining tenant activity) Isolate cupboards, sinks and services from walls.

Rooms adjoining factories and plant rooms

Specialist design criteria.

Noise Control for Hotels, Motels & Boarding Houses MARCH 2006

INTRODUCTIONThough not yet a code requirement, effective noise control has become a prerequisite for client satisfaction.At the top of patrons requirements is a good night’s sleep. Attention to noise control can result in filling more rooms due to repeat custom and referrals.

Areas requiring attention• Noise disturbance can come from neighbouring rooms (adjacent, above or below) in the form of airborne sound from TV and

voices, impacts from footsteps along corridors and stairs, or services like showers and toilets• Noise from impacts travels horizontally along floors as well as up and down; impact through walls can be a concern where there

are no buffers from wardrobes or bathrooms• Noise from lobbies, entertainment and conference rooms can require special attention• Protection from external noise is important near main roads and airports• Room acoustic treatment around receptions in large foyers can aid intelligibility.

The table below summarises general noise control recommendations for hotels, motels and boarding houses.

SPACE HOTELS, MOTELS & BOARDING GUIDE

Rooms Minimum

• Walls and floors STC 53 (for onsite FSTC 48) Floor IIC 55• HVAC PNC 30 dB• External noise intrusion 35 dB(A) maximum.

Rooms Better • Walls STC 58 with discontinuous or resiliently mounted frames (For FSTC 55)• Floor IIC 55• HVAC PNC 25 dB• External noise intrusion 30 dB(A) maximum.

Conference rooms Specialist acoustic design for room acoustics.STC 45 between seminar rooms depending on surrounding background noise.

Entertainment areas Specialist design criteria.

Reception Acoustic ceiling and/or wall treatment NRC 0.8 immediately around reception.

Noise Control Systems for Residential Dwellings MARCH 2006


INTRODUCTIONProviding noise control in the 21st century presents new challenges for homeowners and specifiers. For example, home theatres and stereos deliver unprecedented sound levels, often over 100 dBA and causing particular nuisance at low frequencies.

The different sounds of our modern lifestyles within the confined area of a family home often compete with the different expectations of the occupants. Young adults stay at home longer, long stay guest rooms are popular and parents and children co-exist with competing requirements.

To ensure a comfortable family environment it is important to plan for noise control in the home.

Different areas of the home will require different levels of noise reduction and the designer should play an important part in the process by endeavouring to isolate areas of high volume noise from those requiring near silence e.g. home theatre from bedrooms.

Internal passages, bathrooms and wardrobes etc, can generally isolate such rooms.

As a rule of thumb the following STC values will reduce the sound type and sound pressure given to an acceptable level for most people. It is intended as a guide to assist the designer and homeowner to make an informed choice of what areas and noise level reduction is required.

STC NOISE ROOMS

35 Standard walls: Quiet speech, low level sound Passage walls, kitchen

42-45 Normal speech, snoring, background music Bedrooms, home offi ce

48-52 Raised voices, children at play, loud snoring Master bedroom, rumpus, bathroom/toilet

55-62 Loud music, extreme raised voice, machinery Home theatre, rumpus, garage/workshop

Special care should also be taken with plumbing noise and impact sound associated with shower and toilet areas.

INTRODUCTIONAlthough outside the scope of the NZBC, many unit-to-unit aged-care tenants essentially live in intertenancy situations. Not all are hard of hearing, and when neighbours are hearing impaired, the TV volume may be louder, putting hearing neighbours at greater disadvantage. Moreover, elderly tend to wake more easily so low background noise is important.

SPACE DESIGN GUIDE

Unit to unit walls and floors

Generally the same as for Intertenancy

Unit doors to internal corridor

Solid core with seals

Background noise 30 dB(A) reduction minimum

Bathrooms; walls with sinks or cupboards

STC 55 walls adjoining noise sensitive areas like reception, meeting rooms or offices; isolate plumbing from frames with resilient mounts or use double or staggered frames. Or use a buffer (e.g. a storage room between bathroom and office).

Reception/administration Adequate privacy is generally achieved at STC 45-50

SPECIFIC DESIGNThe design information set out in this literature is necessarily generalised and only applicable to normal situations. Specific acoustic design advice should be sought from an experienced acoustical engineer in less common situations. For instance, inner city apartment developments of more than 5 storeys would usually benefit from specific design since even minor optimisation in construction can result in appreciable cost reductions. Specific design is also required where a residential development is located in a business or industrial zone and a specified internal noise level must be achieved for compliance with a building consent. The information given in this publication is based on normal free flowing traffic as the noise source and different types of noise could change the noise reduction values given. In particular this information should not be used where the noise source is loud or amplified music. Specific design is required in this case.

VARIATION IN SOUND RATINGSThe ability of building materials to resist the transmission of sound is dependent on their density, thickness and stiffness. Generally speaking light and stiff materials have poor sound insulation properties because they allow sound at certain frequencies (near the so-called critical frequency) to transmit easily. Materials of similar thickness and weight can have different sound reduction performance if they have different critical frequencies. For example, laminated glass has a better sound reduction because it reduces the effect of the critical frequency by damping vibration and reducing the stiffness of the window.

MULTI-STOREY BUILDINGSIn multi-storey buildings typical of apartment developments there are fewer transmission paths than traditional, single occupant, single level houses. For instance in the case of a bedroom on a mid level there will be no significant external noise transmission through the roof or the floor since these are shielded by the apartments above and below. Because there are fewer transmission paths the overall noise reduction is greater than a house with roof and floor paths. This factor can be included in the design by using the partial system performances detailed on pages 52, 53 and 54 (types A, B and C construction). Thus for the apartment with only a wall and window path the performance is about 3 dBA higher than the overall system performance. Multi-storey buildings do not often use weatherboards as an external cladding. However, 6mm fibre cement board can be used as an equivalent to 20mm weatherboards. It should be noted that the noise level does not reduce significantly with height in multi-storey buildings even up to 30 stories and so the same construction must be used on all levels.

WINDOW TO WALL RATIOThere is no optimum window to wall ratio. Generally speaking from an acoustic point of view the smaller the window the better since it is often the weakest path and thicker glazing or double glazing is more expensive in comparison to other building systems. The newer types of laminated glazing using a PMM interlayer (e.g. Pilkington HUSH Glass) provide about a 3 dBA improvement over similar thickness float glass. A 3 dBA reduction would otherwise require an increase from say 6mm to 10mm float glass.

ASSUMPTIONS IN DESIGNThe major assumption in design is that the noise spectrum is a traffic noise spectrum. The noise reduction may be a little more for industrial noise which generally has more mid to high frequency and less for low frequency dominated noises such as pubs or night-clubs etc. Another significant assumption is that windows are perfectly sealed. This is a reasonable assumption for aluminium joinery but a poor assumption for timber joinery. We would not recommend standard timber joinery for any noise reduction application above standard construction. Also all design assumes closed windows. Open windows will generally lower the noise reduction to between 10 and 15 dBA.

Fibre cement board (6mm) can be used as an equivalent to 20mm weatherboards. However, if a brick veneer is specified a slightly higher dBA loss can be expected.

Noise levels quoted are average levels. These are Leq for traffic noise, Ldn for aircraft noise and L10 for industrial noise.

AIRCRAFT NOISELdn noise levels quoted are the average levels for aircraft noise.Each airport prepares a set of noise boundaries called the Inner Control Boundary and the Outer Control Boundary. These are based on the 65 dBA Ldn contour and the 55 dBA Ldn contour respectively. Outside the Outer Control Boundary no noise control is deemed necessary. Between the Outer and Inner Control Boundaries housing is a permitted activity but the walls and roof of the house must provide sufficient sound insulation to achieve a reasonable indoor noise level. Inside the Inner Control Boundary housing is generally a controlled or discretionary activity subject to meeting the internal noise levels. The relevant Local Authority sets the indoor level.The most common level is 45 dBA Ldn. These noise levels are subject to change from time to time.The building designer must consult the local authority to ascertain the required indoor level and consult the relevant planning maps to determine the aircraft noise exposure at the proposed building location.

INDUSTRIAL NOISEL10 noise levels quoted are the average levels for industrial noise.Generally when dwellings are built in an industrial or business zoned area the building must be built with sufficient sound insulation to reduce the noise level inside to a reasonable level, assuming that the industry next door is making the maximum noise level permitted by the District Plan rules for that zone. Often this ‘reasonable’ level will be left to the acoustic consultant to determine. The usual indoor level used is a level of 35 dBA for bedrooms at night and 45 dBA for other habitable spaces during the day. The maximum noise level will vary from zone to zone and also from Local Authority to Local Authority.Generally the level will be between 60 dBA and 75 dBA noise levels.Zonings are subject to plan changes and the building designer must consult the local authority to determine the current zoning and noise rules.

INTRODUCTIONAny penetration in a wall, floor, or ceiling (e.g. light fitting, power outlet, pipe, HVAC, door) has the potential to degrade noise control.

FIRE RATINGSIt is important to note that penetrations can also degrade fire ratings. Their effect on fire ratings depends on the specific system and components involved. If a fire rating is also required, the fire rating of the penetration details must be assessed. Reference: Penetrations in GIB® Fire Rated Systems.

HOW PENETRATIONS DEGRADE NOISE CONTROLCommon ways penetrations degrade noise control are:• Introduction of leaks (for example, minute air gaps through door jambs or light switches, or small gaps around pipes or through

down lights)• Replacing a portion of a GIB® Noise Control System with a material that has less noise control (for example a door, flush box or

down light into a wall or ceiling)• Introduction of a structural connection between linings (for example a service pipe connected to both sides of a wall)• Placement of a sound source within a building system (for example a water pipe in a wall or ceiling introduces a noise source

into the cavity. Moreover, mounting the pipe on a frame or lining causes the lining to radiate sound directly which can amplify the sound).

THE IMPORTANCE OF SOUND SEALANTEven minute gaps degrade noise control. Think of filling a room with water – where the water can leak, so can sound.To illustrate this, compare a wall measured in an acoustic laboratory before and after applying sealant to the perimeter. Even though the gaps were tiny (under bottom plates and around plasterboard fixed firmly against plates), without sound sealant the STC rating dropped 20 dB! Mouldings (e.g. architraves), paint and wallpaper are generally not sufficient to stop sound leaks. GIB Soundseal® offers high mass and elasticity to accommodate building movement – do not use a general purpose gap filler.

1. FLUSH BOXESOffset flush boxes in adjacent stud bays. Use GIB Soundseal® around the flush box perimeter, and continue insulation behind the box. Where this is not possible use surface mounted boxes.The diagrams below provide options for flush box placement, cavity insulation, and framing scenarios. Results are for single size flush boxes, no more than four each side of a wall. Note that some options degrade noise control. For single and staggered framed walls rated higher than STC 55 and double framed walls higher than STC 60 the expected degradation may be greater.

2. DOWN LIGHTSIt is best practice to avoid recessed lights in mid floor ceilings. However, where necessary, recessed lights may be used with minimal impact provided, (i) They are positioned less than one every 4m2

(ii) Insulation is used in the ceiling cavity (iii) They are limited to 100mm x 100mm per downlight (iv) They are installed in accordance with the manufacturer’s specification and relevant standards with respect to ventilation

requirements.

3. DOORSThe NZBC has no noise control requirements for doors, including doors from dwellings to corridors. However, doors usually limit the noise control performance of a system and a minimum performance is required to meet design acoustic comfort and satisfy occupants.

The noise control rating of a wall with a door will usually be limited by the performance of the door, as shown below. Here a 10m2 wall is rated STC 55 (without a door) and a 1.8m2 door assembly rated STC 30 (e.g. a solid core door with perimeter seals) is installed. The total STC for the wall with the door is only STC 36. The door has reduced the wall performance significantly. If the rating of the wall was increased to STC 65, the total rating would still be STC 36.

Acoustic rated wall system limited by door performance

The table below provides examples of how combining different doors and walls affects STC. Wall size relative to door size can make a modest difference.

Effect of Door Type and Door + Wall Area on STC

DOOR + WALL AREA (m2)

36mm HOLLOW CORE DOOR – NO SEALS = STC 18 36mm SOLID CORE DOOR WITH SEALS = STC 30

DOOR + STC 55 WALL DOOR + STC 55 WALL

6 24 34

10 25 36

15 27 38

20 28 39

Therefore, it is essential to select a door assembly consistent with the design comfort level.

• Communicating doors STC ~ 45 to 50 Pairs of back-to-back doors (solid core with seals) separated by 30mm or more, with sound absorbing material on one face

• Proprietary noise control doors STC ~ 36 to 50

• Sound lobby STC ~ 50+ Usually comprises two solid doors with seals separated by a small room.

Note: Where sound passes through a door, along a corridor, and through another door there is essentially a sound lobby.

Steel Framing – Installation Details MARCH 2006

Fastening GIB® Plasterboard to Metal StudsCorrect methodAs the face of a steel stud can deflect initially, the correct sequence of attaching the board is important. The first board is attached to the open side of the stud which will cause minor deflection but will pull back tight against the board when the screw is fully tightened.When the second sheet is fixed there will be minimal deflection as the open flange is now supported by the previous sheet.Support the stud to avoid twisting.

Flat joint Second sheet First sheet

Correct fixing direction

First sheet Second sheet Second sheet Lipped joint Twisted stud

Incorrect fixing direction

Incorrect fixing method results in lipped joints or twisted studs misalignment of the wall.

Plasterboard Fixing SequenceFix the boards in the sequence as shown below A,B,C,D,E,F.Install A and B first at the edges only THE CENTRE MUST NOT BE FIXED until the C and D boards have been installed. Locate board joints on alternate studs on each side of the frame. Tighten fasteners in the numbered sequence as below 1 - 6. Correct fixing sequence will minimise misalignment and result in a higher quality finish.

Double stud sound control systems are recommended for intertenancy construction. They achieve the best laboratory performance for sound control and are least prone to on-site performance reductions due to workmanship, penetrations, flanking paths, etc.

GIB® Quiet Tie® has been designed to provide a structural connection between the frames of double stud walls, whilst maintaining the STC rating of the system. No reduction in sound transmission loss is expected for double frame walls up to STC 68.

Connections may be required for seismic reasons to control independent lateral movement of adjacent floors during an earthquake, resulting in unpredictable impact loads. Specific design is required to determine the appropriate spacing of the GIB® Quiet Tie®.

The GIB® Quiet Tie® has a design capacity of 4 kN in tension and 2 kN in compression (compression loads will also be partially absorbed by mineral fibre packing between frames at floor levels).

Connections are also required to ensure that the stability of double frame walls is maintained in the case of a fire on one side of the wall. New Zealand Loadings Standard NZS 4203:1992, Clause 2.4.3.4 addresses this issue. Two methods are proposed:

• Design the element and supporting structure to resist fire emergency loads during and after the fire. This would require a detailed analysis of both the expected fire conditions, and the response of structural elements at the predicted elevated temperatures; or

• Design the element and supporting structure so that the residual structure is able to resist the fire emergency loads plus a uniformly distributed face load on the residual structure of 0.5 kPa.

Assuming a complete fire-cell burnout, the residual structure (the intertenancy wall) must be able to resist a 0.5 kPa face load. For inter-storey heights between 3 and 4 metres, and stud spacing of 600mm, the recommended spacing is one GIB® Quiet Tie® every third stud (1.8 metres) along the wall bottom plate and at roof level if required.

GIB® Quiet Tie® is distributed by MiTek New Zealand. Fastening instructions are included in the packaging.

Detail at roof level (if required by engineer)

Place the GIB® Quiet Tie® as near as possible to the top or bottom of the stud(one half of the tie is rotated 90˚ in this case).
