Ceiling surfaces

There are several other types of ceiling finishes other than wallpaper. These include polystyrene tiles; veneer-sheet polystyrene in different patterns and textured effects; textured ceiling papers, wood cladding; illuminated ceilings and decorative plaster finishes.

The reasons for applying a decorative ceiling finish may be to:

• Provide a decorative surface;

• Disguise a badly cracked surface where the plaster is stable, but less than attractive;

• Conceal pipework or unattractive features;

• Reduce height in a high room;

• Add extra insulation and reduce condensation by providing a surface that is warmer to the touch;

• With illuminated ceilings or diffused recessed lighting to produce shadowless lighting or a mood lighting effect.

Illuminated ceilings

An illuminated ceiling is suitable for kitchens and bathrooms but can be used effectively in other areas of the home. It is an ideal way of lowering the height of a room and, at the same time, providing an even, shadowless light.

One system of illuminated ceiling consists of a latticed framework of aluminium or plastic angle strip, inset with panels of textured translucent PVC.

Plastic or aluminium angle strip is obtainable in either natural finish or a variety of colours. Strip can also be painted to match a particular colour scheme.

There are three types of angle strip; 38mm x 19mm ‘L’ or wall angle supporting lengths, which are nailed or screwed to the walls; 38mm x 38mm main supporting tee lengths which span the width of the room and 38mm x 10mm bridging tees, which are placed at right angles to the main supporting tees.

Translucent PVC panels, 2mm thick, can be either white, or coloured to create different lighting effects. Perforated panels are made for use over cookers. All panels are easily cut with a sharp trimming knife and can be removed for easy cleaning.

Before deciding to install this type of ceiling it is important to realise that it will effectively lower the room height by at least 150mm.

This is the minimum gap required to accommodate the concealed light fittings and to allow adequate light dispersal over the area. In fact, a greater gap will allow a better light throw.

Fluorescent strip lighting is normally used with this type of ceiling as it gives an even spread of light. As the PVC panels absorb up to 50 per cent of the light produced, twice the previous light output will be needed to provide the same level of illumination.

As a rough guide, one and a half watts for each 300mm2 of ceiling will give a good general light level. The level of this type of lighting effect is constant for, while it is possible to dim a fluorescent strip light, it is more expensive and more complicated to install than tungsten lighting, as a choke component and a cathode heating transformer are needed.

Before fixing the new ceiling, it is important to prepare the original ceiling area. As the light will now be reflected downwards, this area should be light reflecting.

Either paint the surface with matt white emulsion, high-gloss white paint or line it with aluminium foil. If the latter is used, an anti-fungicidal adhesive paste should be employed. A warm, still area is the ideal breeding ground for fungi.
