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.
Here is a word on prefinished product if they factor into your decision. If you come up short on your order, the next lot that you buy may not match your previous batch. This is especially a problem on the lower end price floors and import floors. Good luck trying to blend it in with your previous floor. So if you go this route, be extra accurate on your measurements. Right now the rage is lifetime warranties on flooring. We stop to think is that really even possible? First will that importer or manufacturer really be around a lifetime? A lot of products are made oversees; the warranty is only good if there is somebody still around for the life of the warranty.
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.
