Hardwood flooring is often a generic term that could apply to any type of wood flooring. Hardwood trees (oak, maple, cherry, walnut, elm, chestnut) are generally trees that had leaves which fall off in the winter. Softwood trees (pine, fir) have needles that may stay on all year and usually they produce cones. Hardwoods are usually more dense and more durable than softwoods. Of course, there are exceptions to these generalities. In our product line the hardwoods cost more than the softwoods.
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.
All joists must extend at least 1-1/2" on to a bearing assembly, of either a beam or full height wall, unless metal hangers are installed to provide proper bearing support against other structural components. Beams, which support the floor joists over greater spans, are constructed in the form of laminated joists often referred to as built up beams, or one piece solid load bearing beams, cut from logs or manufactured. Electricians and plumber may often cut or drill into the joist work to install utilities, and this is accepted, so long as they do not remove more material than what is required by codes. This type of floor system is usually the cheapest to install.
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.
