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.
Did you see a picture that you like and now you have the bug that you want that special floor? The good news is that it could probably be made for you, but before you go a long ways down the path of choosing which floor you want and requesting a display room full of samples, ask about some price ranges. There is a common misconception that since reclaimed wood is supposedly salvaged it should be cheaper than virgin wood floors. If you are buying a quality kiln dried and precision milled product, generally that is not the case. The only cost savings would be if you found some scraps or did some salvage work yourself, you might save some costs. For example you might find a gym floor or planks out of a barn hay loft that you want to nail down on your floor. The material might have been next to free, but how much time are you going to have in making it usable and pulling nails? Are the results what you want?
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.
Wood strip flooring is one of the oldest types of flooring still popular in the modern age. It consists of wood strips, usually interlocking, which are either nailed or glued to the sub-floor. Often the strips will be prefinished, requiring no post applications of sealers or varnishes. This type of flooring is very labour intensive for installation, as well as being quite expensive to purchase. However, the results are a warm, durable floor surface, requiring little maintenance or upkeep. Wood strip flooring significantly adds to the strength of the support system, reducing the deflection ("bounce") and gives the floor a very solid feel to it.
