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.
Most popularly used in bathrooms, kitchens, laundry areas and entryways are vinyl sheet, or linoleum floorings. This type of flooring cones in a vast array of colors, textures and patterns, in sheet sizes of 12 foot widths with varying lengths, and made from a vinyl composite, covered with a surface coating. It is installed by applying covering over the sub-floor, usually mahogany or particle core sheets 4`x4` in size, to which the vinyl is glued to. It can also be installed directly onto concrete floors, in areas such as basements. Joining two sheets together is a standard practice when the room width exceeds 12`, or under doorways. Sheet vinyl is a good flooring in areas where water tends to accumulate, like around bathroom fixtures or at entry ways. It is fairly durable, and often maintenance free. Linoleum is one of the cheapest types of flooring 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.
With reclaimed material waste factor is a huge variable. How much effort does the manufacturer take to give you a 100% usable product? Poorly milled with very little defecting and culling done on a solid wood floor that costs $6/sf and has a 15% waste factor actually costs more than a similar product that is milled better costing $7/sf with a 2% waste factor. That extra wastes costs more in shipping and labor to defect. This is one of the hardest things to demonstrate to a customer that the face value costs doesn`t necessarily represent the actual raw material cost unless one is truly comparing identical quality and specified products.
