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.
Most popularly used in bathrooms, kitchens, laundry areas and entryways are vinyl sheet, or linoleum floorings. This type of flooring cones in a vast array of colors, textures and patterns, in sheet sizes of 12 foot widths with varying lengths, and made from a vinyl composite, covered with a surface coating. It is installed by applying covering over the sub-floor, usually mahogany or particle core sheets 4`x4` in size, to which the vinyl is glued to. It can also be installed directly onto concrete floors, in areas such as basements. Joining two sheets together is a standard practice when the room width exceeds 12`, or under doorways. Sheet vinyl is a good flooring in areas where water tends to accumulate, like around bathroom fixtures or at entry ways. It is fairly durable, and often maintenance free. Linoleum is one of the cheapest types of flooring to install.
Another good flooring for wet areas is the vinyl tile. Typically it is manufactured in much the same way as sheet vinyl, but is much more rigid and comes as 12"x12" square units. They are installed in the much the same way, but require skilled tradesmen, familiar with proper installation. A good installer will start from the middle of the room to ensure that all cut tiles are equal in width at opposing walls. One advantage to this type of flooring, over sheet vinyl, is that it is can be installed, without danger of joint separation, over large areas. For this reason, it is often used in commercial buildings where large rooms are the norm. Vinyl tile can also be easily installed directly to concrete floors. Like vinyl sheets, it too is resistant to water, and tends to be installed in the areas of a building, prone to water accumulations. Tile, can be easily cleaned, is relatively maintenance free, and one of the cheaper finished floors to install.
Most commonly installed are interlocking sheathing panels. This type of sheathing is generally 5/8" thick, and manufactured as either plywood or aspenite (commonly referred to as "chipboard") in 4` x 8` sheets. The sheets come with the long edges designed to interlock with a tongue on one edge, and a grove on the opposing edge. They are installed by simply pushing or pounding the sheets together, and nailing or screwing them to the joist work, in the same manner as raw sheathing. It is often the cheapest to install.
