Flexible Plasterboard CurveBoard Design Freedom and Flexibility

CurveBoard is the ideal solution for creating curves on interior walls and ceilings, giving endless design freedom and flexibility. CurveBoard provides another option in the creation of interior spaces.

Designed as a complete plasterboard wall and ceiling lining system which provides a flat, blemish free and monolithic surface which is ready for decoration. CurveBoard is designed to bend to a tight radii without prior wetting.

CurveBoard Plasterboard:

  • provides design flexibility and freedom
  • enables construction of contoured walls or ceilings
  • allows bending to small radii
  • has recessed edges on long edges to provide a continuous surface once flushed
  • saves time and money on installation requiring curved surfaces
  • lightweight and easy to install
  • can be easily applied to timber or light-steel framing
  • can be easily finished in a number of finishes

Product Description

CurveBoard flexible plasterboard enables the creation of curves on internal walls and ceilings. CurveBoard is manufactured as 6.5mm thick plasterboard enabling the plasterboard to bend to tight radii without prior wetting.

CurveBoard is purpose designed as a complete plasterboard wall and ceiling lining system which complies with the requirements of the Building Code of Australia (BCA).

CurveBoard provides a flat, blemish free, monolithic, smooth surface ready for decoration.

CurveBoard can be fixed to timber or CFS (Cold Formed Steel) light-steel framing using plasterboard screws or nails.

Applications

CurveBoard is suitable for creating curved surfaces on internal walls and ceilings.

CurveBoard is available in a sheet size of 3600mm x 1200mm x 6.5mm.

Advantages

  • Provides flexibility and freedom to construct contoured walls or ceilings
  • Allows bending to small radii
  • Has recessed edges on long edge to provide a continuous surface once flushed
  • Saves time and money on installations requiring curves
  • Lightweight and easy to install
  • Can be easily applied to timber or light-steel framing

Performance

BGC CurveBoard must be installed in accordance with the requirements of Australian Standard AS 2589:2007 – Gypsum Linings – Application and Finish.

Wetting of CurveBoard is only required when an extremely tight radii is required or where temperature and humidity are very low.

Horizontal Fix Convex

Framing

CurveBoard may be fixed to timber, CFS light-steel framing or furring channels, which satisfy the BCA requirements and which have been plumbed true and straight.

Timber – 

Timber framing must comply with the requirements of AS1684.1, AS1684.2, AS1684.3, AS1684.4, AS1720.1, AS1720.2 or the BCA.

Light-Steel –

CFS light-steel framing must be in accordance with AS4600 Cold Formed Steel Structure Code, AS3623-1993 Domestic Metal Framing and AS1397-2001. CurveBoard may be fixed to CFS steel framing but must not exceed 1.25mm BMT.

Fasteners

BGC recommends the following fasteners are used:
For Softwood – 25 x 2.8mm
For Timber Framing – 32mm x No.6 Type W
For Lightweight Steel Framing and Furring Channel up to 0.8mm thickness – 25mm x No.6 Type S Needle Point.
For Loadbearing Steel framing 0.8 to 1.2mm thickness – 25mm x No.6 Type S Drill Point
Always ensure that screw guns are adjusted to the appropriate depth.

Installation

Fasteners should be positioned 10-15mm from edges of the sheet and the head should be slightly below the surface of the plasterboard. Care should be taken to avoid damage to the face of the sheet.

Two layers of CurveBoard  are recommended for most applications with the 2nd layer staggered by at least 200mm to avoid joint alignment.

CurveBoard may be attached horizontally or vertically depending upon the framing support and application, however BGC Plasterboard recommend fixing in a horizontal direction which enables CurveBoard to bend easier.

The maximum stud spacing will depend upon the radius required. Additional studs are usually required to support a tight radius. Please refer to diagrams for recommended spacing.

Finishing

CurveBoard can be finished with several different finishes depending upon the function of the space, lighting and the desired decorative surface required. Finish Levels 4 and 5 are used as detailed in AS2589:2007

The use of a preparatory sealer over the entire surface is recommended prior to application of finish.

Storage and Handling

Care should be taken to ensure edges of CurveBoard are not damaged when handling.
CurveBoard should be delivered to site immediately prior to installation to reduce the risk of damage.
CurveBoard should be stacked flat, up off the ground and supported on equally spaced level gluts.
