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.
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.
For the second variable here is a controversial opinion: we do not end match our flooring which means there is no tongue and groove on the ends of the planks. Since we recommend our floor be glued down we say this is an unnecessary expense for the customer. End matching reduces the yield in production and raises labor costs. Most end match profiles are milled so loosely that they really don`t hold the floor in place anyway. The biggest benefit to the installer is that the plank can be cut in half in any place and reused anywhere without have to mate up to a complementary tongue or groove since the end is just square cut. This means all end trim pieces or any waste can be reused. Therefore on our engineered flooring product the waste factor is virtually nothing unless there are angles or radiuses to work around. We also help with waste factor by usually supplying a random width product so when one gets close to the end of a room they can plan the width combination patterns out to not have to rip much off the last row.
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.
