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.
Raw sheathing comes in 4`x8` sheets, most often installed as 3/4" thick plywood panels. This type of sheathing is adequate for spanning joist work spaced up to 24" apart. The sheathing is lain with the joints staggered in such a matter, that no two edge joints line up with adjoining sheets. It is very easy to install, requiring the least amount of labour. The sheets are fastened with either 1-1/2" flooring screws, or 2-1/2" nails, spaced about 8" apart. Although not required, it is a good idea to provide backers or supports under the joints, between sheets which run perpendicular to the framed floor assembly.
If your price-point is not even in the same zip code, maybe it is in a different state, start shopping other options. For example if you are in the $1-2/sf range look at the deep discounters or laminate options. The FSC certified 12mm exterior birch plywood that we use to manufacturer the engineered flooring costs us that much alone, not counting all the other labor and materials.
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.
