However if you go for a quality engineered wood flooring you can even gone as far as to boil a piece of our floor for 30 minutes and the board still will not de-laminate. The 15mm ply wood under core is what gives the flooring the strength and stability is has. Oak is a natural product and when used for flooring the board widths can change in size. This can cause gaps between boards or the floor to buckle and this movement is most commonly caused by the changing of humidity in the environment. Because of the stability of a quality engineered oak floor it is far less prone to this movement. This stability is also becoming of greater importance today due to the fact that an increasing number of properties are having under floor heating systems installed, which of course causes a frequent change in humidity. Having said this I would again like to reiterate that I am writing in regards to a quality, higher spec engineered oak flooring, and I can not talk for all engineered wood floors.
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.
Dust, grit and moisture are gifts of nature and we all have to deal with them. Grit which stems from sand or dirt being tracked from the outdoors on the surface works like sandpaper on the floor finish. Dust mites, balls and the like are merely pulverized bits of dirt which in essence acts in the same way as grit over the long haul on your floors. Once your floor finish gets damaged grit and dust left on the surface tend to discolor the hardwood while being ground into the surface pores with each step made on top of it like a hammer pounding stroke after stroke.
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.
