The manufactured joist, which is a relatively new product, is often manufactured from low cost materials in the shape of an I beam, similar to steel beams in larger buildings. What this means is that the joist is constructed with a thicker top and bottom edge, and generally interlocking aspenite vertically spanning between the two. These systems are very strong, often capable of spanning the entire width of the building.
There are three main types of sub-flooring installed to cover and span the floor structure. It is over this that the finished floor will be placed. The sub-flooring types include raw sheathing, interlocking and strip. It is utilized not only to provide a surface for the interior finishes to be placed on, but also to prevent twisting or torque forces placed on the building. The sub-floor also allows load sharing within the joist framing system. Often the sub-flooring is glued to the joist work to eliminate creaking floors and to prevent the floor joists from turning.
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.
Fifth, compare overall thickness and the height from the top of the tongue or nail groove to the top of the face on the floor. On an engineered floor this is generally the thickness of a wear layer. Most solid wood floors are 3/4" overall before sanding (but some are less) with 1/4" above the nail groove. Our engineered floor is manufactured to equivalent measurements but most engineered floors have a thinner wear layer. This comes down to how many times the floor can be sanded. What kind of finish and texture you want on the floor factors into how deep you will re-sand the floor during refinishing. A number of our reclaimed wood floors are sold with an original texture that shows the old saw marks and character in the floor, so most likely you won`t want to sand this out. As a rule of thumb, the thicker the wear layer then the longer the floor will last.
