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.
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.
Some think of interlocking tiles and immediately think of ugly, heavy, rubber flooring used in the industrial sector. This could not be further from the truth. While interlocking tiles were initially created to serve the industrial sector, they have come a long way since that time. Interlocking floor tiles are now available in an array of finishes and material types. They can be purchased in rubber, plastic, vinyl and porcelain, among many other high quality materials. Virtually any tile material that can be used in a traditional installation can also be used in interlocking floor tiles.
Strip floors, were once the most popular type of sub-floor installed. But with the introduction of manufactured sheathing products, it has become less utilized. Strip floors consist of 1" by 6" or 8" boards, placed diagonally over the floor joist framing system. It is slightly more expensive to install, and requires experienced tradesmen. To install such floors properly, the lumber should be non-kiln dried, with a relatively high moisture content. This may seem odd, but in reality, as the wood dries out, it will shrink.
