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.
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.
Carpet is probably the most common floor covering that is used in residential homes. It comes in a wide variety of colors and textures. Carpet consists of woven fibers, which protrude upwards, glued or woven into a foam or jute backing. Often an underpad of pressed foam is installed below it or the backing can be integral with the carpet, adding to the softness and providing a much more comfortable surface for walking on. Carpet is installed by either gluing the carpet to the sub-floor, or the use of carpet tack around the perimeter. A good carpet will has a close weave, which will not show the backing material when separated. To reduce project costs, some contractors will opt to install a high quality underlay, with a low or medium quality carpet. This provides the soft surface, with equal durability, giving the homeowner the benefits of high quality carpet, at a reduced cost.
