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.
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.
Truss floors are simply that. They are constructed from small dimensioned lumber, interconnected in a webwork pattern by the use of metal or wood plates. Occasionally, the trusses will be built on site, utilizing plywood plates to connect the webwork together. Generally they are installed 24" apart, either suspended on bearing walls or beams, or installed with plywood trim or rim joists around the perimeter. Strapping is installed on the bottom side, to prevent turning in place, which is a common ailment for deep truss components.
