Traditional tile installation requires many tools and lots of patience which have to be pre-set on the floor, cut down to size, then adhered to the floor using a strong industrial glue. They will not stick to every surface and frequently, a layer of floor base must be installed before the tiling work can begin. If the tiles are placed too close together, they can buckle, leaving unsightly bumps and lumps on the floor. If they are placed too far apart, there will be obvious gaps. If a mistake is made when laying down the tile, it is very difficult to fix as the tile is glued to the floor. The tile will have to be pried up, excess adhesive scraped, and the process started over. Laying traditional tile floors is a project that can take several days, to several weeks, to finish.
Of all, the most commonly installed flooring system are framed floors. They consist of dimensioned lumber, bearing on exterior and interior load bearing walls or beams called "floor joists". Generally the floor joists are installed, spaced 16" apart. Installing rim and trimmer joists, to which the floor joists are nailed, finishes the perimeter. Bracing, usually in the form of bridging, but often installed as strapping, prevents the joists from turning in place. One other method used to prevent this type of turning is to glue the sub-flooring to the joists, as the sub-floor is placed.
One drawback is that this type of floor requires special hanger systems designed for the joists, to enable them to be hung from each other or against beams/bearing walls. Manufactured joists are becoming a popular flooring system, for they are relatively cheap, reduce labour time and provide adequate support. However, builders need to familiarize themselves with its installations, for poor installation can cause severe structural damage to the joists. A good example is a three point, center bearing joist, left with the top chord uncut, which can potentially fail or pull apart, over the center bearing point.
Truss floors are simply that. They are constructed from small dimensioned lumber, interconnected in a webwork pattern by the use of metal or wood plates. Occasionally, the trusses will be built on site, utilizing plywood plates to connect the webwork together. Generally they are installed 24" apart, either suspended on bearing walls or beams, or installed with plywood trim or rim joists around the perimeter. Strapping is installed on the bottom side, to prevent turning in place, which is a common ailment for deep truss components.
