How Much Wallpaper To Use
To calculate the wall angle strip needed, measure the complete perimeter of the room. The length of main supporting and bridging tee angle strip depends on the size of panel used.
The main supports must be the width of the room and the number required will depend on the size of the panels and the number consequently needed to fit across the room.
The amount of bridging tee angle is calculated in the same way. These bridge either a main or a pair of supports and a wall angle along the length of the room.
To calculate the number of panels needed, establish the ceiling area and divide the panel size into this.
Before fixing the new ceiling, provision must be made for the lighting fitments. A fluorescent strip can replace a tungsten fitting.
However, as the light level needs to be even, two or more strip lights, dependent on the area to be covered, will provide better light distribution. These lights can be jointly or independently switched.
Decide on the position of the ceiling and mark this line round the walls. Use a lm-long spirit level to ensure that the horizontal line is true. Mark round the room, a metre section at a time, to ensure complete accuracy.
Fix the ‘L’ or wall angle at 300mm intervals, using masonry, or fix by plugs and . Once the outside support is fixed, the rest of the ceiling can be laid into position.
Place the main supporting tee widths into position, resting, at each end, on the wall angle. Over widths greater than 366m, extra joining clips are used to lengthen the support strips. These clips need additional support.
Loop a piece of wire round the angle tee, at the join, securing this to a ceiling fixed hook. The bridging tees are put into position between the support tees ready to receive the panels, which slide in diagonally, and are turned and lowered into position.
Unless the panels fit exactly to the room module-which is usually not the case-the edge panels will need cutting to fit.
An attractive, but not illuminated ceiling, can be made by using acoustic ceiling tiles set in plastic angled strip with main and bridging tees used as sup- ports as in the illuminated-ceiling system. The framework can be set as near or as far from the original ceiling surface as required. Acoustic tiles are made from flame-resistant polystyrene. These cut down on noise level, and the brilliant white of the ceiling reflects all the available light downwards.
