So, a top quality oak engineered flooring will look the same but will it actually last as long?. How long a floor will last is mostly down to something called its `wear layer`. The part of the floor that is classed as the wear layer is from the surface of the board down to the tongue and on a solid oak board this would be around 5-6mm. Now, the wear layer on engineered wood flooring is the top layer of oak. So if you purchase an engineered oak flooring which has a 5-6mm solid oak top layer it will result in the flooring lasting just as long. In conclusion if you want an engineered flooring that is going to last as long as a traditional solid oak floor then make sure it has a nice thick top layer of wood, ideally 5mm+.
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.
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.
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.
