Today we’re going to be discussing the consumer’s most versatile ceiling option, that being a grid system of T-bar shaped metal tracks with either 2’x2’ or 2’x4’ sized tiles, otherwise known as a suspended ceiling.
Suspended ceilings are popular, especially in basement renovations, because the manor of assembly is a relatively quick learn, and a natural progression for those homeowners who received gold stars in kindergarten for their excellence in manipulating Lego blocks.
The grid system is comprised of four basic components — a 12 ft. wall angle, a 12 ft. main tee, along with 2 ft. and 4 ft. cross tees. The strategy to assembling the grid components in a basement involves following three basic steps. One, the 12 ft. wall molding gets installed first, using regular wood or drywall screws, and follows the entire perimeter of the room. Next, sit the edges of the 12 ft. main tees in the L-shape of the perimeter molding, making sure they lie perpendicular to the floor joists above. Then, space these main tees four feet apart.
Whether the ceiling space is square or rectangular is irrelevant. Spacing the main tees four feet apart allows you to lay the tiles (if we’re talking 2’x4’ panels) in whatever direction you wish. Laying the main tees perpendicular to the floor joists, allows you to easily support these main tees with wires strung down from screws inserted into the joists. Place a supporting wire every four feet along the length of your main tee. With the perimeter moldings installed, and the main tees secured in position, two and four foot cross tees can then be installed. This, in a nutshell, are the basic steps regarding the installation of a suspended grid.
Now, however simple this procedure seems, frustration and profanity will be your future if you don’t come up with a strategy beforehand. Because the cross tees insert quite easily, but are about as much fun to disconnect as having to undue a tight knot in a shoelace, you’re only going to want to fasten a cross tee to a main tee, or cross tee into an adjoining cross tee, once.
Getting every connection right the first time you assemble grid in a room requires either a lot of previous practice, or a plan. So, assuming you’re not a professional ceiling installer, let’s come up with a plan that’ll leave all our trials and errors on a few sheets of paper in the recycle bin. On a sheet of graph paper, outline the exact co-ordinates of the room. In order for the ceiling panels to be easily placed into the track, the entire grid system must hang four inches below the lowest beam or length of ductwork. Please understand that the four inch drop is a minimum. With the main tees measuring about two inches in depth, a four inch minimum drop leaves you with about two inches of air space to slide in, and manipulate a tile into position. If you’ve purchased a ridged tile, and because of their superior quality and sound attenuation value, I definitely recommend that you do, these panels are going to be a son of a gun to handle if you’ve shorted yourself drop space. If dropping the grid system four inches below the lowest beam is going to create a living hazard for those with futures in basketball, with the proposal that persons susceptible to head scuffing protect themselves with the coveted basement helmet, receiving little praise, then the beam may have to be left as is. In cases such as these, beams get boxed-in with drywall, or simply painted, to somewhat camouflage their existence, with the grid systems butting up to it on either side. In most basements, it’s not so much the low lying beams, as much as the low lying ductwork, that can make finishing a ceiling all the more difficult.
