The manufactured joist, which is a relatively new product, is often manufactured from low cost materials in the shape of an I beam, similar to steel beams in larger buildings. What this means is that the joist is constructed with a thicker top and bottom edge, and generally interlocking aspenite vertically spanning between the two. These systems are very strong, often capable of spanning the entire width of the building.
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.
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.
