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.
Are you going to be able to enforce the warranty? Also, do you really think that a finish can last a lifetime? For example take a nail and try scraping it across the surface. Sure it is a durable, well applied finish, but it is impossible to make a product that won`t get abused at some point in its lifetime. Do you think that the only serious trial your floor will ever see is a stinky sock? Read the fine print on the warranty and regardless of what it says consider the true replacement cost on the floor. It probably only covers the cost of material of the specific damaged product under normal wear and tear. Your product may not be made exactly the same later (trends and product lines change) to replace the section that is warrantied, so you may have to replace the whole floor years later. You will have labor cost along with displacement of trim, cabinets, and appliances. Also most of these lifetime finishes cannot be repaired or sanded because of a micro bevel put on the edge of prefinished floor. Our advice is instead to buy a quality product that can be refinished and repaired because something will go wrong in the lifetime of the floor; don`t get a false sense of security.
Strip floors, were once the most popular type of sub-floor installed. But with the introduction of manufactured sheathing products, it has become less utilized. Strip floors consist of 1" by 6" or 8" boards, placed diagonally over the floor joist framing system. It is slightly more expensive to install, and requires experienced tradesmen. To install such floors properly, the lumber should be non-kiln dried, with a relatively high moisture content. This may seem odd, but in reality, as the wood dries out, it will shrink.
All joists must extend at least 1-1/2" on to a bearing assembly, of either a beam or full height wall, unless metal hangers are installed to provide proper bearing support against other structural components. Beams, which support the floor joists over greater spans, are constructed in the form of laminated joists often referred to as built up beams, or one piece solid load bearing beams, cut from logs or manufactured. Electricians and plumber may often cut or drill into the joist work to install utilities, and this is accepted, so long as they do not remove more material than what is required by codes. This type of floor system is usually the cheapest to install.
