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.
Working in the flooring industry we often have customers calling us because they are interested in a solid oak floor. More often than not we end up suggesting they go down the engineered route and then being asked the same thing, `why choose an engineered wood floor over a solid oak floor and does it really feel and look as beautiful?` We are writing this article to briefly outline the main advantages of our engineered wood flooring and why now so many people are choosing the engineered over the traditional solid oak flooring. Throughout this article I will write in reference to a top quality engineered oak flooring with multiple layers of ply wood under core and a thick, long lasting wear layer. I can not speak on behalf of all engineered wood floors as they differ massively in quality and price. In all cases you need to check thoroughly the specifications of the product on offer.
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.
Most commonly installed are interlocking sheathing panels. This type of sheathing is generally 5/8" thick, and manufactured as either plywood or aspenite (commonly referred to as "chipboard") in 4` x 8` sheets. The sheets come with the long edges designed to interlock with a tongue on one edge, and a grove on the opposing edge. They are installed by simply pushing or pounding the sheets together, and nailing or screwing them to the joist work, in the same manner as raw sheathing. It is often the cheapest to install.
