GypWall CLASSIC and GypWall ROBUST

The definative metal studand partition system

GypWall CLASSIC partitions arecost-effective, multi-purpose partitions, which have provided theindustry standard for many years.They are suitable for all types ofbuildings, including residential,healthcare and commercial.

GypWall ROBUST is a high impact-resistant partition system foruse where a more durable structure is required. It provides a lightweight,cost-effective, non-loadbearing partition suitable for all types ofcommercial, healthcare, institutionaland industrial buildings.

Construction tips

l Estimated construction time 2m2 - 3m2 / man hour (single layer partition) or 1.5m2 - 2m2 / man hour (double layer

partition) ready for finishing

l Use full height boards wherever possible - if horizontal joints are unavoidable, endeavour to position them above

the suspended ceiling or below access floor level. Avoid eyeline and strong wall lighting areas

l Fixtures / fittings - additional framing will be required to support heavyweight items (e.g. sanitary ware)

l Support horizontal joints with Gypframe GFT1 Fixing ‘T’, Gypframe GFS1 Fixing Strap or Gypframe 99 FC 50 Fixing

Channel (where specified)

l Where single layer Gyproc DuraLine (GypWall ROBUST) is being fixed to Gypframe 'C' Studs these should be

a minimum gauge of 0.6mm - unless using Gypframe AcouStuds

l Install Gyproc Control Joints where specified

l Incorporate deflection heads where specified

l Consider skirting fixing - mechanical or using Gyproc Sealant

l If doorsets are fixed at a later stage allow a 10mm overall tolerance in width, 5mm in height

l Consider additional door detailing to BS 5234

• Determine and mark the wall positionand make allowance for openings.

• Fix Gypframe Floor & Ceiling Channelalong the centre line to the floor andceiling at 600mm centres with suitablefixings.

• For GypWall ROBUST use Gypframe DC or EDC Floor & Ceiling Channels.

• On uneven floors, a timber sole plate,38mm deep x width of stud, may berequired.

• On new concrete or screeding, considerinstalling a damp proof membrane to thefull partition width before locating thefloor channel or sole plate.

• 94mm and 148mm channels requiretwo rows of staggered fixings (600mmcentres in each row).

• For partition heights between 4200mmand 8000mm Gypframe Deep FlangeFloor & Ceiling Channel (DC) should beused at head and base (subject todeflection head).

• For partitions above 8000mmGypframe Extra Deep Flange Floor &Ceiling Channel (EDC) should be used athead and base (subject to deflectionhead).

• Cut studs to a neat fit (maximumpossible entry into head and basechannel).

Cut studs to size using a chopsaw, hacksaw or snips.

For deflection heads, the methodwill vary to suit requirement.

• Locate the first stud, twist into positionand fix to the abutting wall at 600mmcentres.

• Locate further studs at 600mm centres to a friction fit within the channel sections - this allows for adjustment during boarding. Positionthe studs so all face the same way.

• Where studs are used at heights greaterthan 4m, consider locking into the floorchannels using a Gyproc Crimping Tool, orGyproc Wafer Head Screws.

• Apply Gyproc Sealant to both sides ofthe frame perimeters to provide optimumacoustic performance.

Light and Medium Duty dooropenings

• Locate full height studs each side of thedoor opening. Fix to the Gypframe Floor &Ceiling Channel at base using GyprocWafer Head Drywall Screws or GyprocWafer Head Jack-Point Screws, orcrimping tool (dependant on the studtype and gauge).

• Line the opening with timber - 38mmdeep x width of stud, and fix through themetal frame into the timber.

• Fix the door casing to the timberground.

Advice should be sought from the door manufacturer prior to the construction of these details.

• Sleeve the studs either side of theopening with channel section, stopping300mm short of the floor channel.

• Allow for extension of floor channel.This is then cut, bent, and interleaved asshown in section A-A, and then fixedtwice to each side.

• At the head, cut and bend channel toextend 150mm down the face of thestuds, and fix twice to each side of eachstud.

• Install Gypframe 150 FC 90 FixingChannel to accommodate heavyweightfixtures. If a plywood pattress is required,Gypframe Service Support Plates shouldbe used.

Services

• Install services (by appropriate trades),normally after one side is boarded. Passhorizontal runs through cut-outs in thestuds and install Gypframe 99 FC 50Fixing Channel or Gypframe Floor &Ceiling Channel between studs to providesupport for recessed switch boxes.

• The position of cut-outs is the same foreach Gypframe 'C' Stud and Gypframe 'I'Stud.

Board fixing - single layer

• Fix boards to all framing members at300mm centres using the appropriatelength Gyproc screws.

• Reduce centres to 200mm at externalangles.

• Lightly butt boards, inserting screws notcloser than 10mm from bound edges and13mm from cut edges.

• Install Isover insulation or stone wool(as required) progressively as boardingproceeds.

• Isover insulation can be hung within thepartition by trapping at the partition headusing Gypframe Steel Angle.

• Where door openings occur, cut boardsaround the opening to avoid a jointdirectly in line with door jambs.

• Adjust studs as boarding proceeds andstagger board joints relative to theopposite side.

• Board partition in the direction of studflanges as shown above.

Board fixing - multi-layer

• Under-layer boards do not requirecentre fixings. Cut and fix the initialsecond layer board as appropriate so thatsubsequent board joints are staggered.

• Fix outer layer boards to all framingmembers at 300mm centres usingappropriate length Gyproc screws.Reduce centres to 200mm at externalangles.

• Typical double layer boardconfiguration is as above.

• If Gyproc Plank forms the base layer, fixhorizontally with two 32mm GyprocDrywall Screws to each stud position,including each cut end. Half stagger endjoints in alternate layers.

• Seal any gaps at the base of linings toboth sides with Gyproc Sealant (inconjunction with Gyproc Joint Filler)where the partition is required to meet itsoptimum acoustic performance.

Horizontal joint support - single layer

• Where the partition height exceeds theboard length, install Gypframe GFT1 Fixing‘T’ progressively across studs to coincidewith board end joints, to maintain boardalignment and to ensure systemperformance. Fix boards progressively tosupports using Gyproc Drywall Screws ofappropriate length.

It is important that boards are levelledon their top edge. Position the top screwinto the stud nominally 30mm down toallow the Gypframe GFT1 Fixing ‘T’ to beinstalled. Lightly butt and lift boards to theGypframe GFT1 Fixing ‘T’ as workprogresses. Position the next lift of boardsto sit on the Gypframe GFT1 Fixing ‘T’.

Horizontal joint support - multi-layer

• Where the partition height exceeds theboard length, install Gypframe GFS1Fixing Strap progressively between boardlayers, to coincide with outer layerhorizontal board end joints, to maintainboard alignment and to ensure systemperformance.

• Fix boards progressively to supportsusing Gyproc Drywall Screws ofappropriate length.

Splicing studs

• To extend studs, overlap by 600mm(minimum). Fix together using GyprocWafer Head Drywall Screws or steel poprivets (two to each flange), or by using theGyproc Stud Interlocking Tool twice toeach flange.

Boxing studs

• Nest studs with minimum half overlap,allowing for an off-set at head and baseto facilitate normal engagement intochannels. Lock together at 600mmcentres using a Gyproc Stud InterlockingTool or Gyproc Wafer Head DrywallScrews, at 600mm centres on eachflange.

Gyproc Stud Interlocking tool isnot recommended for partition heightsabove 6 metres.

Large service openings

• Construct a framed opening, as shownabove.

In fire-rated partitions, the servicepenetration should be fire-stopped, asspecified by the appropriate contractor.

Deflection head

• Form the firestop at the head usingGyproc Plank with continuous line of GyprocFireStrip. Gypframe Deep Flange Floor &Ceiling Channel is fixed through firestop tosoffit at 600mm centres using suitablefixings. No fixings should be made throughthe boards into the flanges of the headchannel. The arrow ( ) denotes theposition of the uppermost board fixing,which should be made into Gypframe GFS1Fixing Strap or Gypframe stud nogging,ensuring the downward movement of thehead channel is not impaired.
