Armstrong ceiling is the most common design system. Its popularity is explained by the low price of the necessary components, simplicity and speed of installation, ease of maintenance. The Armstrong system consists of the design of profiles specially attached to the ceiling and gypsum boards fixed to this structure. In addition, you can mount special raster lamps, ventilation elements, loudspeakers.
Necessary components: profiles, quick-suspensions, accessories. The main components necessary for assembling the Armstrong system are metal profiles. They are of three types:
- bearing profile (3 meters and 60 centimeters);
- perpendicular additional profile (1 meter and 20 centimeters);
- transverse additional profile (60 centimeters).
Armstrong ceiling in calculations
The length of the profiles is a multiple of 6, since the side of the Armstrong plate is 60 cm long. In order to calculate the required amount of materials, you need to know exactly the dimensions of the room in which the Armstrong system will be installed. At the same time, the ceiling may not be rectangular in shape, and with dimensions not exceeding 3.6 m. This system can be used in almost any room.
In order to calculate the required number of plates and profiles, you need a sheet in a cage. Just remember that one square is not 50x50 cm, but 60x60.
Further consider as follows:
1. Draw a figure identical in shape to the ceiling.
2. Every 2 cells draw a strip - these are bearing profiles, the length of which is 3.6 m.
3. Every 2 cells perpendicular to the carrier draw a contrasting color stripes. These are additional profiles, the length of which is 1.2 m.
4. Connect additional profiles transverse.
5. Calculate the perimeter and divide the resulting number by 3. This will be the number of corner profiles (3 meters long).
6. Calculate the number of profiles of each color and the number of square-plates. If you plan to install lamps or other elements, their number must be subtracted from the number of plates.
7. The number of quick suspensions depends on the characteristics of the room. It can be roughly calculated as follows: the number of bearing profiles is multiplied by 3.
False ceiling "Armstrong". Installation procedure
Before proceeding directly to the installation, it is necessary to lay all the communications on the ceiling: wiring,
alarm, fire system, and also bring all the electrics to the lamps, if they are installed.
The installation sequence is the same as the calculations. Before installing the Armstrong ceiling, you must use the level to determine its lower boundary. It is advisable to outline or mark the entire perimeter with a laser. Scheme of further work:
1. Attach corner profiles. This can be done using self-tapping screws.
2. Mark the attachment points of the main profiles (every 120 centimeters), fasten them with quick suspensions, about 3 pieces per profile.
3. Perpendicular to the carriers, install profiles of 120 centimeters in length.
4. Perpendicular to them to install profiles 60 centimeters long.
5. Install plates, fixtures.
Exploitation
With proper installation and respect, the Armstrong ceiling can last for many years. Its undoubted advantage is the ability to easily dismantle any part of it to access various parts of the ceiling, if necessary, for example, if the wiring is damaged , or lamps are replaced .
