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.
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.
Laying the floor is also another area that is worth thinking about when comparing the two types of oak flooring. The majority of engineered wood floors are longer and wider than most solid oak boards because this is the look that most people are wanting nowadays. The flooring being longer and wider means the flooring is quicker to fit. Another aspect that makes this floor easier and quicker to fit is how well machined the boards are. From our experience in the flooring industry we have had nothing but good feedback regarding how easy our engineered flooring was to lay, and this is down to how well machined the boards are. Given that engineered flooring is quicker and easier to fit, any extra money that is spent on purchasing an engineered oak floor is often compensated in the time that is saved fitting it! This is something to keep in mind when comparing prices.
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.
