Frequently Asked Questions
RhinoBoard 12.5 mm is used for ceilings, drywall partitions and interior wall lining. It provides a smooth, strong and fire-resistant surface suitable for residential and commercial applications, offering excellent base quality for painting or plaster finishing.
Yes. RhinoBoard has a non-combustible gypsum core that helps improve the overall fire performance of a partition or ceiling system. When installed in the correct system, it contributes to meeting fire safety standards.
No. Standard RhinoBoard is not suitable for wet or high-moisture environments such as showers or exterior walls. For moisture-prone areas, a moisture-resistant board type should be used instead.
A standard board is 1200 mm wide and usually 2400 mm long, although lengths such as 2700 mm, 3000 mm and 3600 mm are also available depending on stock and project requirements.
Cutting is simple: score the board with a utility knife along a straight edge, snap it cleanly, and cut the back paper to finish. This method ensures fast and accurate sizing on-site.
RhinoBoard can be finished using jointing compound such as RhinoGlide or a skim coat of RhinoLite plaster. Both provide a smooth, paint-ready finish suitable for interior decoration.
RhinoBoard provides good acoustic performance when used in a proper partition system with insulation and sealed joints. Actual sound reduction depends on framing, insulation type and board configuration.
What framing systems are compatible?
Yes. It is lightweight, easy to handle, simple to cut and fast to install on ceilings and partitions. Screws, jointing tapes and proper framing ensure a professional finish.
Boards must be stored flat, on a level surface, protected from moisture and outdoor weather. If stored on concrete floors, place a moisture barrier or timber battens underneath.
