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.
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.
Raw sheathing comes in 4`x8` sheets, most often installed as 3/4" thick plywood panels. This type of sheathing is adequate for spanning joist work spaced up to 24" apart. The sheathing is lain with the joints staggered in such a matter, that no two edge joints line up with adjoining sheets. It is very easy to install, requiring the least amount of labour. The sheets are fastened with either 1-1/2" flooring screws, or 2-1/2" nails, spaced about 8" apart. Although not required, it is a good idea to provide backers or supports under the joints, between sheets which run perpendicular to the framed floor assembly.
Seventh, are you a do-it-yourselfer? Think through every step of the process to be sure that you can do it yourself. Usually the install can be done with relatively moderate skills and simple tools like a chop saw and rented flooring nailer. The finishing process is a whole different matter. The sanders and buffers take some special skills to operate. A normal price range for labor and materials to install a wood floor is $4-5 per square foot. It is possible to build your own sweat equity into a floor install. Maybe this is where you choose to use our engineered product for example because it is presanded to more accurate tolerances than a solid wood product. It can be touched up with a hand held orbital sander rather than industrial floor sanders. Then if you are doing the finish yourself, you will want to consider using a finish that may not require as much buffing between coats.
