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.
In the case of long span truss work, bearing lengths of at least 3" are quite common. Trusses span greater distances than framed floor assemblies and can be designed to span the entire building, eliminating center load bearing supports. They are moderately more expensive than framed floor assemblies, but provide a remarkably strong floor with little deflection or "bounce" to it. Another advantage to this type of structural system, is that utility installations can be run between the webwork components. Never allow trades to cut or drill into the members of a truss, for they are manufactured precisely for the loading conditions they will undergo during the life of the building.
With reclaimed material waste factor is a huge variable. How much effort does the manufacturer take to give you a 100% usable product? Poorly milled with very little defecting and culling done on a solid wood floor that costs $6/sf and has a 15% waste factor actually costs more than a similar product that is milled better costing $7/sf with a 2% waste factor. That extra wastes costs more in shipping and labor to defect. This is one of the hardest things to demonstrate to a customer that the face value costs doesn`t necessarily represent the actual raw material cost unless one is truly comparing identical quality and specified products.
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.
