Raw sheathing comes in 4`x8` sheets, most often installed as 3/4" thick plywood panels. This type of sheathing is adequate for spanning joist work spaced up to 24" apart. The sheathing is lain with the joints staggered in such a matter, that no two edge joints line up with adjoining sheets. It is very easy to install, requiring the least amount of labour. The sheets are fastened with either 1-1/2" flooring screws, or 2-1/2" nails, spaced about 8" apart. Although not required, it is a good idea to provide backers or supports under the joints, between sheets which run perpendicular to the framed floor assembly.
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.
Of all, the most commonly installed flooring system are framed floors. They consist of dimensioned lumber, bearing on exterior and interior load bearing walls or beams called "floor joists". Generally the floor joists are installed, spaced 16" apart. Installing rim and trimmer joists, to which the floor joists are nailed, finishes the perimeter. Bracing, usually in the form of bridging, but often installed as strapping, prevents the joists from turning in place. One other method used to prevent this type of turning is to glue the sub-flooring to the joists, as the sub-floor is placed.
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.
