Interior Linings & Ceilings

Interior Linings


The plasterboard options are increasingly varied as manufacturers produce interior wall boards with noise reduction, additional insulation, fireproof and waterproof for different applications.

  • There are alternatives to plasterboard, too. Plywood, wood veneer panels, glass and fiberglass have been used and there are now also bamboo sheets.
  • Negative details create clean, sharp lines that leave ceilings floating or subtly frame walls with recessed channels surrounding windows, doors, and at wall-to-floor ceiling junctions.
  • Feature walls and ceilings can be created with other techniques such as bulkheads, false beams, partitions, curved walls, voids or recesses to create interest, separate spaces an style. Talk to your designer
  • Level 4 and 5 finishes are most commonly specified in residential home construction.
  • Level 4 is the generally accepted level of finish; it is used where non-critical lighting falls on satin/flat/low sheen paints or wallpaper.
  • Level 5 is for use where gloss, semi-gloss or dark tone paints are specified or where critical lighting conditions occur on satin, flat matt or low sheen paints.
  • The key difference between Level 4 and 5 is that level 5 requires the entire surface of the wall or ceiling is covered in a thin layer special compound called a "skim coat" to remove surface textures and porosity. Stricter framing and installation requirements are also needed to ensure a level 5 finish is achieved. Due to the extra labour costs, the skim coat process can add an extra $150-$250 to the cost of one 15m2 wall.

ceiling - an overhead interior surface that covers the upper limit of a room. It is generally not a structural element, but a finished surface concealing the underside of the floor or roof structure above.

Ceilings are classified according to their appearance or construction. A cathedral ceiling is any tall ceiling area similar to those in a church. A dropped ceiling is one in which the finished surface is constructed anywhere from a few inches to several feet below the structure above it. This may be done for aesthetic purposes, such as achieving a desirable ceiling height; or practical purposes such as providing a space for HVAC or piping. An inverse of this would be a raised floor. A concave or barrel shaped ceiling is curved or rounded, usually for visual or acoustical value, while a coffered ceiling is divided into a grid of recessed square or octagonal panels, also called a lacunar ceiling. A cove ceiling uses a curved plaster transition between wall and ceiling; it is named for cove molding, a molding with a concave curve.
