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.
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.
Dust, grit and moisture are gifts of nature and we all have to deal with them. Grit which stems from sand or dirt being tracked from the outdoors on the surface works like sandpaper on the floor finish. Dust mites, balls and the like are merely pulverized bits of dirt which in essence acts in the same way as grit over the long haul on your floors. Once your floor finish gets damaged grit and dust left on the surface tend to discolor the hardwood while being ground into the surface pores with each step made on top of it like a hammer pounding stroke after stroke.
When it comes to price, interlocking floor tiles are significantly less expensive than standard tiles. The need for additional flooring or plywood, adhesive, tools and man hours can make standard floor tiles thousands of dollars more expensive than interlocking floor tiles. Interlocking floor tiles require very few tools and in most cases, can be placed directly on the floor and hammered in with a rubber mallet. They are also much easier to install without the assistance of a professional. This eliminates the need to hire expensive contractors to do the work. People who choose interlocking floor tiles can expect to save anywhere from $500 to $5000 depending on the area being tiled and the expense of the tile chosen. For a percentage of the traditional tile cost, those who choose interlocking tiles receive the same quality floor or better.
Fourth, factor in the cost of refinishing the floor later or doing touchups. This is a whole another article. Some finishes can be spot touched up like some of the oils while others require a full sand over the whole floor. Some finishes require a professional installer and may have extreme odor during the cure. If you live with the floor for very long, factor these decisions in for the type of finish to choose for lifetime durability and the cost & effort to refinish.
This shrinking action pulls the floor together, adding strength to the overall system. The advantages of this type of sub-floor are its strength and durability. One important note, homeowners are often disturbed by the small 1/4" wide gaps, generally left between the individual planks after the wood dries out. Although disturbing to see during construction, upon completion, the spaces are not noticeable, and really have no impact on the sub-floor components at all. Strip floors are designed to be interlocking, through lapping or spacing of joints.
