Of all the wood flooring, the most often installed is the parquet tile. They consist of square interlocking wood strips, held together with glues and/or metal wires. Often they come as single 6"x6", or multiple 12"x12" square tiles, about 1/4" thick. They are glued directly to the sub-flooring, and are strong enough to span small deviations in it. The wood is often prefinished, and requires little maintenance. Parquet floors are a cheaper alternative to strip flooring, providing the same warm, durable surface.
Here is a word on prefinished product if they factor into your decision. If you come up short on your order, the next lot that you buy may not match your previous batch. This is especially a problem on the lower end price floors and import floors. Good luck trying to blend it in with your previous floor. So if you go this route, be extra accurate on your measurements. Right now the rage is lifetime warranties on flooring. We stop to think is that really even possible? First will that importer or manufacturer really be around a lifetime? A lot of products are made oversees; the warranty is only good if there is somebody still around for the life of the warranty.
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.
