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.
Fifth, compare overall thickness and the height from the top of the tongue or nail groove to the top of the face on the floor. On an engineered floor this is generally the thickness of a wear layer. Most solid wood floors are 3/4" overall before sanding (but some are less) with 1/4" above the nail groove. Our engineered floor is manufactured to equivalent measurements but most engineered floors have a thinner wear layer. This comes down to how many times the floor can be sanded. What kind of finish and texture you want on the floor factors into how deep you will re-sand the floor during refinishing. A number of our reclaimed wood floors are sold with an original texture that shows the old saw marks and character in the floor, so most likely you won`t want to sand this out. As a rule of thumb, the thicker the wear layer then the longer the floor will last.
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.
Fourth, factor in the cost of refinishing the floor later or doing touchups. This is a whole another article. Some finishes can be spot touched up like some of the oils while others require a full sand over the whole floor. Some finishes require a professional installer and may have extreme odor during the cure. If you live with the floor for very long, factor these decisions in for the type of finish to choose for lifetime durability and the cost & effort to refinish.
