What is H-Strip Ceiling?

Materials will consist of 6mm Rhino-boards nailed to and including 32mm x 32mm branders with metal cover strips and 75mm Rhino-cornices. This type of ceiling can be fitted in any house or room, but is a very ordinary ceiling and the cheapest option to install.

What is Plastered Ceiling?

Plastered ceilings:
Materials for this ceiling will consist of 9,5mm Rhino-boards screwed to and including 32mm x 32mm branders with Fiba-tape over the joints of the boards and Polystyrene cornices. Plastering of complete ceilings with Rhinolite will follow installation. This type of ceiling is mostly fitted in entertainment areas and main bedrooms. It is more expensive, but adds value to your home.



Flush Plastered Ceilings are usually suspended below roof beams or a slab. They are constructed with a Rhinoboard and then skim plastered using Rhinolite plaster.


Plastered Ceilings give a high end and elegant finish.

Flush Plastered Ceilings can be finished with a decorative cornice or designer ceiling trim to create clean lines, subtle curves, shadows, and different levels and features.

This is an extremely versatile ceiling application, so an architect can make full use of this kind of ceiling as a design feature.

They are usually thicker than standard ceilings therefore providing good sound resistance and insulation. Beautiful and stylish bulkheads can be easily integrated into a design using this type of ceiling.

Typical Applications:

Plastered Ceilings or Fixed Ceilings are popular for Residential and Commercial Ceiling applications. Malls, offices, airports and shops including designer homes make wide use of Plaster Ceilings due to the versatility it offers.

Two common methods are:

  • Suspended. A metal ceiling grid can be hung from a special bracket or metal strap fixed to the underside of the floor slab or truss. Suspension brackets lock into a series of interlocking metal sections. Next assembly of a galvanized grid begins, the grid clips securely into place.
  • Wood or metal brandering grids. With this method the grid is fastened directly to the roof trusses, thus forming a series of lines perpendicular to the trusses.

The installer will fasten Rhino or Jumbo boards to the frame using screws or nails. It is important to apply a special Fibre tape to reduce the chance of cracking at joints where boards meet. This is when the fun starts. The plasterer will then apply a thin coat of Rhinolite or skimming plaster evenly across the boards. Finally the plasterer will float the ceiling to a smooth finish. It is vital that materials used in installation of ceilings and bulkheads comply with South African building standards therefore insuring the installation is safe and protects the owner from liability issues.

When the plaster has dried a decorative moulded cornice or other ceiling trim can be fixed at the corners where the wall and roof meet to create the desired effect.

What are Suspended Ceilings?

Suspended ceilings (sometimes referred to as dropped ceilings or false ceilings) are secondary ceilings suspended from the structural floor slab above, creating a void between the underside of the floor slab and the top of the suspended ceiling.

As well as concealing underside of the floor slab, this void can provide a useful space for the distribution of heating, ventilation and air conditioning (HVAC) services and plumbing and wiring services, as well as providing a platform for the installation of speakers, light fittings, wireless antenna, cctv, fire and smoke detectors, motion detectors, sprinklers and so on. The void can also be used as an air ‘plenum’, in which the void itself forms a pressurised ‘duct’ to supply air or extract it from the occupied space below.


Suspended ceilings can allow easy access to services by the removal of tiles, or through access panels and can allow flexibility of layout of spaces below. However, they do result in some loss of headroom (generally at least 100mm).

Typically suspended ceilings are hung from a bracket fixed to the underside of the floor slab supporting a series of interlocking metal sections that form a grid into which panels such as ceiling tiles can be fitted. Beam systems are also available, in which tiles are laid between parallel beams rather than a grid, and there are a wide range of different grid profiles and tile edge details that can be used to allow the grid to be exposed, flush, recessed or concealed.

Tiles may be manufactured from materials such as mineral fibre, metal, plasterboard and laminates and are often perforated to provide specific levels of acoustic absorption that can be used to control the

Careful design is required to ensure integration with partition systems so that tiles, grids and partitions intersect neatly.

Partitions may stop at the underside of the suspended ceiling to provide maximum ease of installation and flexibility, or may run through the ceiling to the underside of the floor slab. Where partitions do not run through the ceiling void, care must be taken to ensure that a flanking path is not created for the transmission of sound between adjacent spaces or for the spread of fire. Acoustic insulation or fire separation can be provided in the ceiling void if necessary.

The selection of suspended ceilings may depend on:

  • Aesthetic considerations.
  • The requirement to incorporate fittings necessary for building services.
  • Requirements for acoustic attenuation and absorption.
  • Hygienic requirements.
  • The need to provide fire
  • Moisture resistance
  • Corrosion resistance
  • Cleaning requirements.
  • Thermal insulation.
  • Tile thickness and size.
