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.
This shrinking action pulls the floor together, adding strength to the overall system. The advantages of this type of sub-floor are its strength and durability. One important note, homeowners are often disturbed by the small 1/4" wide gaps, generally left between the individual planks after the wood dries out. Although disturbing to see during construction, upon completion, the spaces are not noticeable, and really have no impact on the sub-floor components at all. Strip floors are designed to be interlocking, through lapping or spacing of joints.
When it comes to price, interlocking floor tiles are significantly less expensive than standard tiles. The need for additional flooring or plywood, adhesive, tools and man hours can make standard floor tiles thousands of dollars more expensive than interlocking floor tiles. Interlocking floor tiles require very few tools and in most cases, can be placed directly on the floor and hammered in with a rubber mallet. They are also much easier to install without the assistance of a professional. This eliminates the need to hire expensive contractors to do the work. People who choose interlocking floor tiles can expect to save anywhere from $500 to $5000 depending on the area being tiled and the expense of the tile chosen. For a percentage of the traditional tile cost, those who choose interlocking tiles receive the same quality floor or better.
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.
