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.
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.
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.
Installing interlocking floor tiles is a much easier and user friendly process. They are designed to clip together, eliminating the need for measuring spaces and also leaving room for the tiles to settle. Each tile is surrounded with divots that lock to the other interlocking floor tiles. They clip together easily, much like a jigsaw puzzle, and allow a perfect seamless finish. If a mistake is made while installing the interlocking tiles, it is easy to fix. Simply pull them apart and start over. As no adhesive is generally used, they do not need to be pried up, risking damage to the floor.
