Another good flooring for wet areas is the vinyl tile. Typically it is manufactured in much the same way as sheet vinyl, but is much more rigid and comes as 12"x12" square units. They are installed in the much the same way, but require skilled tradesmen, familiar with proper installation. A good installer will start from the middle of the room to ensure that all cut tiles are equal in width at opposing walls. One advantage to this type of flooring, over sheet vinyl, is that it is can be installed, without danger of joint separation, over large areas. For this reason, it is often used in commercial buildings where large rooms are the norm. Vinyl tile can also be easily installed directly to concrete floors. Like vinyl sheets, it too is resistant to water, and tends to be installed in the areas of a building, prone to water accumulations. Tile, can be easily cleaned, is relatively maintenance free, and one of the cheaper finished floors to install.
In the case of long span truss work, bearing lengths of at least 3" are quite common. Trusses span greater distances than framed floor assemblies and can be designed to span the entire building, eliminating center load bearing supports. They are moderately more expensive than framed floor assemblies, but provide a remarkably strong floor with little deflection or "bounce" to it. Another advantage to this type of structural system, is that utility installations can be run between the webwork components. Never allow trades to cut or drill into the members of a truss, for they are manufactured precisely for the loading conditions they will undergo during the life of the building.
The manufactured joist, which is a relatively new product, is often manufactured from low cost materials in the shape of an I beam, similar to steel beams in larger buildings. What this means is that the joist is constructed with a thicker top and bottom edge, and generally interlocking aspenite vertically spanning between the two. These systems are very strong, often capable of spanning the entire width of the building.
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.
