Application Instructions
- Use for ceilings fixed onto recommended framing or ceiling grid systems (e.g. brandering + ceiling grid or support as specified by Gyproc).
- Boards should be fixed at right angles to brandering or support framing, printed side up.
- Screw or nail at correct spacing per manufacturer guidelines (e.g. 150 mm centres) for secure fixing.
- Joints may be covered with M-Strip / jointing tape + skim coat plaster for a smooth ceiling finish.
- Cut using utility knife and straight-edge scoring & snapping method for clean, precise cuts.
- Protect boards from moisture before and during installation — not suitable for wet areas or continuous moisture exposure.
Suitable Applications
- Residential ceilings in houses, apartments, villas
- Interior ceilings for offices, light commercial spaces (non-load bearing)
- Ceiling bulkheads, soffits, decorative ceiling features
- Dry interior ceilings where minimal thickness and lightweight ceiling board is desired
- Budget-conscious projects requiring a smooth ceiling finish with basic fire and structural performance
Compatibility & Limitations
- Compatible with standard Gyproc ceiling systems / approved brandering or framing support
- Not suitable for external walls, wet areas (bathrooms / kitchens) or areas with continuous moisture exposure
- Not recommended for load-bearing walls or heavy-duty partitions — only for ceilings or non-structural interior surfaces
Safety & Handling
- Store boards flat on level supports, in dry, covered area before installation
- Handle boards carefully — lift from long edge to avoid damage
- Wear gloves, dust mask and safety eyewear when cutting or installing plasterboard
- Keep boards dry at all times — avoid water, rain or direct damp contact before and during installation
Frequently Asked Questions
RhinoBoard 6.4 mm is designed primarily for interior ceiling installations in residential buildings. It offers a lightweight, smooth gypsum board ideal for false ceilings or bulkheads, providing a clean surface ready for paint or plaster finish without heavy structural requirements.
No, RhinoBoard 6.4 mm is not recommended for wall partitions. Its thin profile suits ceiling applications only. For partitions or load-bearing walls, use thicker boards such as 9 mm or 12.5 mm that provide better structural strength and stability.
Standard RhinoBoard 6.4 mm is not moisture-resistant and should not be used in bathrooms, kitchens or damp zones. For humid conditions, a moisture-resistant or specially treated board is recommended to prevent damage or mould growth.
Boards are fixed perpendicular to brandering or ceiling grid, printed side up, using screws or nails spaced per manufacturer guidelines. Joints are covered with joint tape or M-Strip and optionally skim-coated for a smooth finish. Boards should be stored and handled in a dry environment.
Once installed, RhinoBoard 6.4 mm ceilings can be painted directly or skim-coated with plaster. The smooth gypsum surface accepts paint or plaster well after joints are properly sealed, yielding a professional-looking ceiling finish.
Yes — the board is made from gypsum with waste classified as inert and non-hazardous, and it is fully recyclable. Using RhinoBoard supports sustainable building practices and reduces construction waste impact.
6.4 mm RhinoBoard is lighter, easier to handle and install, and more cost-effective — ideal for simple interior ceilings where heavy-duty strength or sound insulation is not required. It reduces labor and material costs for basic ceiling work.
Yes — as a gypsum-based board, RhinoBoard 6.4 mm offers inherent fire-resistant properties thanks to the chemically bound water in gypsum. It provides basic fire protection suitable for standard ceiling applications in homes and offices.
Store RhinoBoard flat on level, dry supports in a covered, moisture-free environment. Avoid stacking boards directly on damp concrete or in exposed outdoor conditions to prevent warping or damage before installation.
Yes — the board is easy to cut using a utility knife and straight-edge scoring with a snap-back method. Its lightweight and aerated gypsum core make on-site adjustments convenient and efficient, enabling quick installation for ceilings or bulkheads.
