General Information

PRODUCTSKnauf Drywall Metal Sections are manufactured from mild steel sections coated with either a zinc electrolytic process or hot dip galvanised process.This is then cold formed to the required section profile.

LimitationsKnauf Drywall Metal Sections are not suitable for use in load bearing situations.

If metal sections are to be used in areas of high humidity cut edges must be treated with suitable zinc based primer.

Knauf Drywall Metal Sections are not designed for external use.

Site StorageKnauf Drywall Metal sections are supplied in small packs and then strapped together to form larger packs for forklift truck off-loading. These packs can be stacked in single packs, in a safe and stable manner on a flat surface.

These bands or straps should not be used for lifting. Metal sections may spring apart when banding is released.

Note: If handling manually, consider risks as required by Manual Handling Regulations 1992.

HEALTH & SAFETYKnauf Drywall Metal Sections must be handled with care as formed edges and cut ends may be sharp. Gloves should be worn when handling the material to avoid lacerations.

Avoid prolonged contact with skin and wear protective clothing when handling metal components.

Safety glasses should be worn when using power tools.

Head protection should be worn when working with overhead hazards.

An on-site risk assessment should be carried out before use.

For the latest Material Safety Date Sheets on the specific products, please contact Knauf Hong Kong.

PARTITION DUTY - STRENGTH AND ROBUSTNESS

The wall duty-strength and robustness-ratings are grouped as follows:-

Suggested minimum sound insulation values of partitions:-

• Stiffness• Surface damage by small hard body impact.• Resistance to damage by impact from a large soft body.• Eccentric downward loading of heavyweight anchorage ( wash basin )• Eccentric downward loading of heavyweight anchorage ( high level wall cupboard )

• Crowd pressure• Perforation by small hard body impact.• Resistance to structural damage by impact from a large soft body.• Door slamming• Pull-out of a lightweight anchorage.• Pull-down of a lightweight anchorage.

Knauf Partitioning System provides strength and robustness. These duty ratings have been calculated in accordance with BS 5234 : Part 1 & 2 : 1992. The rating is a measure of the ability of the wall to meet the requirements of strength and robustness tests:

As an aid to specification, the figures below are guidelines for duty-strength / robustness rating, and minimum sound reduction values for partitions separating various room types.

Suggested minimum sound insulation performance levels for privacy in some occupational conditions are given in table below. The values given are based on laboratory measurements.

11

GeneralKnauf Performer partitions must be installed in accordance with Knauf Drywall’s recommendations and the recommendations of BS 8212: 1995 and BS 8000; Part 8: 1994.

Perimeter FramingKnauf ‘U’ Channels should be used for the head and base of the partition. Knauf ‘C’ Studs should be used to form any abutments and to frame openings. Bed each section on two continuous beads of Sealant or Intumescent and Acoustic Mastic as specified. Secure with suitable fixings at maximum 600mm centres and 50mm from ends of channels or studs. Separate studs and channels forming the perimeter need not be joined, but should be tightly butted together.

Replace Knauf ‘U’ Channel with a Knauf Deep Flange ‘U’ Channel when forming a deflection head.

Partitions constructed to provide fire and / or acoustic separation are required to span from structural floor to structural soffit.

Vertical StudsStuds should be postitioned within the channels to coincide with the abutments of the boards, at centres dependant on the performance requirement of the system. In general there is no requirement to secure the metal at this point as this will be achieved once the boards are screw-fixed.

Knauf ‘C’ Studs should be trimmed to within 5mm of the slab to soffit height. For deflection heads: studs should be cut short to allow for required clearance within Knauf Deep Flange ‘U’ Channel.

Knauf ‘C’ Studs can be extended by forming a splicing detail. See details on page.

InsulationSubject to the performance requirements once the studs have been located in the Knauf ‘U’ Channels and one side has been boarded, Knauf insulation as specified should be inserted between the studs vertically. Care should be taken to ensure that the insulation is fitted neatly without gaps at abutments or vertically between different rolls.

Support for HorizontalJoints in FacingsTo back horizontal joints in outer board layers, Knauf Fixing Channel or Knauf Flat Fixing Plate should be fitted across the face of all studs, secured with 2 Knauf Drywall Screws per stud to both faces or between board layers.

DoorwaysThe head is formed with Knauf Deep Flange ‘U’ Channel, snipped and bent back and screw fixed with Knauf Screws to the studs.

BoardingAll boards should be offered up to

the frame with the face of the board outwards and secured with Knauf Drywall Screws at 300mm maximum centres. Fixing centres should be reduced to 200mm at corners.

Boarding should commence at one end and work across the partition. At head, floor and abutments, board edges should be bedded on to continuous beads of Sealant. Board joints in multiple layers should be staggered both vertically and horizontally by at least 600mm.

Deflection HeadsThe maximum deflection should be no more than half the flange length of the Knauf Deep Flange ‘U’ Channel and for a downward direction.

After fixing the head track, the floor track should bepositioned by using a vertical stud and a laser/spiritlevel.

‘Knauf ‘C’ ChannelForms the main supports

‘C’ ChannelsThe lower ‘C’ channels are clippedto the upper ‘C’ channels by meansof channel intersection connectors.The spacing of the upper ‘C’channles varies according to the weight of the ceiling specified.

BulkheadsThe framing for bulkheads is builtup from standard ‘C’ and ‘U’channel components.

Access panelsAccess panels can be provided inthe ceiling between supportchannels. Framing is formed with‘C’ channels connected by meansof noggin channel connectors. Theopening is then ready to receive aproprietary access hatch.

It should be used for larger ceiling areas (50m2 andover) and for spans over 4m. It is also ideal for wheredeeper ceiling voids are required (over 450m).

The system utilises one or more layers of any of theKnauf range of plasterboards, depending on the performance required. The boards are fixed onto a double lightweight metal framework of Knauf ‘C’Channels and Knauf ‘U’ Channels.

The lightweight galvanised is suspended by eitherstrap hangers or angle sections fixed to the structuralsoffit with soffit cleats.

Suspension Rods andAdjustable Channel HangersThe suspension rods support theupper ‘C’ channels of the system,the height of which can be adjustedby means of the movable channelhangers. Spacing depends on theweight of the ceiling (see loadinginformation, page 46). Additionalsuspension rods can be used tosupport point loads such asluminaires.

Perimeter channelsProvide support at the edges of the ceiling and consist of ‘U’ channelsections. These are screw-fixed toperimeter walls at the level of thelower ‘C’ channel supports. ‘U’channels are also used to build upthe framing for bulkheads, changesof level and access panel openings.

‘U’ Mounting BracketsAn optional fixed hanger which isscrew-fixed directly to the structuralsoffit, for use where clearanceabove the plasterboard is not sufficient for suspension roads andadjustable channel hangers.

Noggin Channel ConnectorsWhen KNAUF plasterboard mustbe supported at all four edges, orwhere a point load requires supportbetween the lower ‘C’ channels,channel sections are fitted betweenthe lower ‘C’ channels andconnected by means of nogginchannel connectors.

Better safety

AQUAPANEL®Cement Board Outdoor is a super-fast building

material: no drying time is needed and surface are already even. This

means your constructors can get the job done faster, doing other

building activities in parallel. You can sell and/or rent your building

sooner.

And it is not just the construction stage that is super fast. You

can use the library of certified and proven technical solutions and

technical details to fast-track the planning of your new building.

Other AQUAPANEL®tools and services support the design,

development, prototype mock-up and implementation phases

including calculation of windloads and recommendations on sub-

structure. It all adds up to faster return on investment.
