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.
Hardwood flooring is often a generic term that could apply to any type of wood flooring. Hardwood trees (oak, maple, cherry, walnut, elm, chestnut) are generally trees that had leaves which fall off in the winter. Softwood trees (pine, fir) have needles that may stay on all year and usually they produce cones. Hardwoods are usually more dense and more durable than softwoods. Of course, there are exceptions to these generalities. In our product line the hardwoods cost more than the softwoods.
We personally do not care for prefinished flooring due to installation problems associated with it, so our product requires site applied finish. This means that your floor finish if site applied will be easier to sand and refinish than a prefinished floor. Also you do not have to deal with that micro bevel groove between each board that tends to fill up with dust and crumbs. Most prefinished hardwood floors really can`t be refinished easily. To sand it off means that the wear layer has to be thicker than the height of the nails and have room to sand off the micro bevel between boards; that amounts to a lot of sanding. You also will not be able to spot sand or touch up parts of the floor.
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.
