GypLyner

GypLyner wall lining is acost-effective, virtuallyindependent metalframe dry internal lining.It is a general purposesystem which is non-loadbearing and suitablefor all internalapplications. It can beused in all building typesranging from privatehouses to largecommercialdevelopments. Theinherent versatilitymakes it equally suitableas a wall and ceilinglining.

Planning the job1 Estimated construction time is 3m2 / man hourready for finishing.

2 The depth of the cavity is determined by thepositioning of the fixing brackets. Allow for a stand-off of 25mm - 75mm plus the lining thickness for GL2Brackets, and 25mm - 125mm plus the liningthickness for GL9 Brackets.These stand-offs aresufficient to correct irregularities normallyencountered in solid backgrounds.

3 The drylining cavity must be ‘closed’ otherwisethermal performance will be downgraded. This isachieved in practice if the abutting elements and thebackground are well fitted, and junctions are sealed.When the perimeter of the cavity is to be sealed by thedrylining contractor, apply a continuous fillet ofGyproc Dri-Wall Adhesive or Gyproc Sealant to theperimeter of the external wall and around any servicepenetrations and openings. Make provision forrestricting air movement around the perimeter ofsuspended timber floors, such as the provision of aflexible seal between the floor and walls.

4 Brackets should be positioned equidistant at max.800mm vertical centres. Where there is a requirementfor increased rigidity, these support centres should bereduced accordingly, although acoustic performancemay be downgraded. Contact British Gypsum forguidance.

5 Where there is a requirement for a more durablelining, 13mm DuraLine may be used in place of either12.5mm or 15mm WallBoard, or 12.5mm FireLine,giving equal performance.

6 Consider a damp proof membrane on new concreteor screeded floors.

7 Use full height boards wherever possible – if jointsare unavoidable endeavour to position them abovesuspended ceilings or below access floor level.

8 Support horizontal board joints with GypframeFixing ‘T’.

9 Select the right length of drywall screws (nominalentry into metal of 10mm).

10 Form vertical cavity barriers, where specified, inlong runs of lining.

• Cut reveal and soffit boards to width,locate into the perimeter edge bead andfix to channel/track.

• Fix boards to complete drylining at theopening.

• Where door openings occur in the runof lining, cut board around the openingto avoid a joint directly in line with doorjambs.

Insulation

• If Isowool insulation is specified, installprogressively as boarding proceeds.Services

• The drylining cavity facilitates theincorporation of services. Fix pipes andconduits in position before installing theframing.

The insulating backing of Gyprocthermal laminates should not be chasedto accommodate services. PVC coveredcables must not come into contact withpolystyrene insulation. Use suitable isolation methods (conduit or capping).
