In this article we will be discussing several different categories of wood flooring. Solid wood flooring is one board with no glued up laminations; it is basically wood board that has been sized and profiled to a certain dimension. Engineered flooring has a on the top whatever species and texture you want, and this is glued to a plywood backer on the bottom. Engineered is still all wood but is made with multiple layers that are laminated for better stability and dimensional accuracy. Floors that we will not cover here are laminates or any composite products which are often not wood entirely through the plank or may be made with a photo printed surface. We also will not cover vinyl, carpet, stone, or tile.
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.
If your price-point is not even in the same zip code, maybe it is in a different state, start shopping other options. For example if you are in the $1-2/sf range look at the deep discounters or laminate options. The FSC certified 12mm exterior birch plywood that we use to manufacturer the engineered flooring costs us that much alone, not counting all the other labor and materials.
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.
