All joists must extend at least 1-1/2" on to a bearing assembly, of either a beam or full height wall, unless metal hangers are installed to provide proper bearing support against other structural components. Beams, which support the floor joists over greater spans, are constructed in the form of laminated joists often referred to as built up beams, or one piece solid load bearing beams, cut from logs or manufactured. Electricians and plumber may often cut or drill into the joist work to install utilities, and this is accepted, so long as they do not remove more material than what is required by codes. This type of floor system is usually the cheapest to install.
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.
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.
Wood strip flooring is one of the oldest types of flooring still popular in the modern age. It consists of wood strips, usually interlocking, which are either nailed or glued to the sub-floor. Often the strips will be prefinished, requiring no post applications of sealers or varnishes. This type of flooring is very labour intensive for installation, as well as being quite expensive to purchase. However, the results are a warm, durable floor surface, requiring little maintenance or upkeep. Wood strip flooring significantly adds to the strength of the support system, reducing the deflection ("bounce") and gives the floor a very solid feel to it.
