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.
Moisture is definitely a no-no when it comes to your hardwood floor. Even though you know that trees are grown from a major ingredient of water, you also know that water aids wood in changing its shape. Just for kicks, ask yourself this question: Would you wash down your intricately etched wood and antique finished dresser, curio or bedroom suit with any type of water solution? Your wooden floor needs that same type of care and attention in order to yield many years of comforting wood floor sheen, elegance and beauty.
Of all, the most commonly installed flooring system are framed floors. They consist of dimensioned lumber, bearing on exterior and interior load bearing walls or beams called "floor joists". Generally the floor joists are installed, spaced 16" apart. Installing rim and trimmer joists, to which the floor joists are nailed, finishes the perimeter. Bracing, usually in the form of bridging, but often installed as strapping, prevents the joists from turning in place. One other method used to prevent this type of turning is to glue the sub-flooring to the joists, as the sub-floor is placed.
