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.
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.
The third variable is installation costs. Our engineered product has labor savings over our solid wood product because it is pre-sanded and milled to tighter tolerances. It is also prefilled in the holes and has next to zero waste. On the other hand you may have a little more in cost of gluing it down in addition to nails, but this is just a step in direction of better quality and peace of mind during the install.
Hardwood flooring is often a generic term that could apply to any type of wood flooring. Hardwood trees (oak, maple, cherry, walnut, elm, chestnut) are generally trees that had leaves which fall off in the winter. Softwood trees (pine, fir) have needles that may stay on all year and usually they produce cones. Hardwoods are usually more dense and more durable than softwoods. Of course, there are exceptions to these generalities. In our product line the hardwoods cost more than the softwoods.
