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.
Laying the floor is also another area that is worth thinking about when comparing the two types of oak flooring. The majority of engineered wood floors are longer and wider than most solid oak boards because this is the look that most people are wanting nowadays. The flooring being longer and wider means the flooring is quicker to fit. Another aspect that makes this floor easier and quicker to fit is how well machined the boards are. From our experience in the flooring industry we have had nothing but good feedback regarding how easy our engineered flooring was to lay, and this is down to how well machined the boards are. Given that engineered flooring is quicker and easier to fit, any extra money that is spent on purchasing an engineered oak floor is often compensated in the time that is saved fitting it! This is something to keep in mind when comparing prices.
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.
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.
