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.
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.
Most commonly installed are interlocking sheathing panels. This type of sheathing is generally 5/8" thick, and manufactured as either plywood or aspenite (commonly referred to as "chipboard") in 4` x 8` sheets. The sheets come with the long edges designed to interlock with a tongue on one edge, and a grove on the opposing edge. They are installed by simply pushing or pounding the sheets together, and nailing or screwing them to the joist work, in the same manner as raw sheathing. It is often the cheapest to install.
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.
