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.
The final advantage of engineered wood flooring over solid oak flooring that I am gong to mention is how an engineered oak floor is more environmentally friendly. The plywood that is used is made up of fast growing softwoods which are plentiful and this is what the under side of our engineered wood flooring is constructed of. This means that far less of our valued oak, which has taken hundreds of years to grow, is used resulting in a much more environmentally friendly flooring.
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.
