One drawback is that this type of floor requires special hanger systems designed for the joists, to enable them to be hung from each other or against beams/bearing walls. Manufactured joists are becoming a popular flooring system, for they are relatively cheap, reduce labour time and provide adequate support. However, builders need to familiarize themselves with its installations, for poor installation can cause severe structural damage to the joists. A good example is a three point, center bearing joist, left with the top chord uncut, which can potentially fail or pull apart, over the center bearing point.
Ah the finished floor, what we see and walk on everyday. For homeowners, this tends to be one of the more important aspects of the floor system. Yes the structure is a consideration, but the look and texture of the floor is what all that will be visible after construction is completed. The most common installed floor finishes include: vinyl sheet, vinyl tile, ceramic tile, wood strip, wood parquet, and carpet.
Of all the wood flooring, the most often installed is the parquet tile. They consist of square interlocking wood strips, held together with glues and/or metal wires. Often they come as single 6"x6", or multiple 12"x12" square tiles, about 1/4" thick. They are glued directly to the sub-flooring, and are strong enough to span small deviations in it. The wood is often prefinished, and requires little maintenance. Parquet floors are a cheaper alternative to strip flooring, providing the same warm, durable surface.
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.
