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.
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.
Fourth, factor in the cost of refinishing the floor later or doing touchups. This is a whole another article. Some finishes can be spot touched up like some of the oils while others require a full sand over the whole floor. Some finishes require a professional installer and may have extreme odor during the cure. If you live with the floor for very long, factor these decisions in for the type of finish to choose for lifetime durability and the cost & effort to refinish.
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?
