Main beams for the ceiling grid come in 12' lengths. What if a room is twice that in length? Is there a way to interlock those things together? I know that the secondary 4' pieces lock onto the main beams, though.
You are correct that the Main T's are 12' long and yes you can connect those with each other. Here is how you do it! If you do not own a rotary laser level you can probably rent one at an tool rental store. Alternatively you can also measure the desired height from the floor (giving it is level) and snap a line with an chalk line on every wall. Now you will mount the wall angle along the walls (try to hit studs normaly16 on center) once you completed this you need to install hangers every 2-4' to hang your wire from ( your rafters may be 24 on center) I would use the recommended screws for it, if you have the framing in the ceiling exposed you also can hang the suspension wire from the rafters that will support your T's. to verify level you can use a level or pull a string across your main T's. Now you can install all your cross T's they come in 2' + 4' length you should have your main T's spaced accordingly. Now you can insert the Ceiling Tile, install only on row at the time if you want to install Bat Insulation on top of it. If you planing on installing recess Lights I would install those drops before the main T's because it is easier to move your grid out the way. If you want to use florescent lights you need to support all 4 corners of your Main T's around the light fixture to support the weight. One last tip: Buy your supply s from an Distributor for Armstrong that will save you a bunch of cash in comparison to an Home Improvement Store like Lowe's or Home Depot Good Luck
Suspended acoustical ceiling systems can be installed to lower a ceiling, finish off exposed joints, cover damaged plaster, or make any room quieter and brighter. The majority of the systems available are primarily designed for acoustical control. However, many manufacturers offer systems that integrate the functions of lighting, air distribution, fire protection, and acoustical control. Individual characteristics of acoustical tiles, including sound-absorption coefficients, noise-reduction coefficients, light-reflection values, flame resistance, and architectural applications, are available from the manufacturer.
