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.
Ceramic tile is probably the most durable types of flooring and is typically installed in entry areas, where sand scuffing and water accumulations are the norm. Bathrooms and kitchens often get this type of floor treatment as well, but due to the high cost of installation, homeowners tend to not include these areas. Ceramic tile are typically a square tile, although interlocking units are on the market, in standard square measurements of 4", 6",8" or 12". They are installed by one of two primary methods, either set into a thin mortar bed (called "thinset adhesive"), which also acts like glue, or a heavyset bed of 1-1/2" normal mortar base. For all ceramic tile installations, the floor must be built up to ensure the strength required to prevent tile or joint cracking. Often, installers put down a material called "cement board", which is much like drywall, but is made of glass fibers and cement. In any case, ensure that your installer will offer you a guarantee against future cracking or uplift of tiles. Ceramic tiles require little maintenance, but beware, water on glossy floor tiles can be very slippery, and many a time, a homeowner has resented the installation of a high gloss tile, over a bathroom floor area.
Fifth, compare overall thickness and the height from the top of the tongue or nail groove to the top of the face on the floor. On an engineered floor this is generally the thickness of a wear layer. Most solid wood floors are 3/4" overall before sanding (but some are less) with 1/4" above the nail groove. Our engineered floor is manufactured to equivalent measurements but most engineered floors have a thinner wear layer. This comes down to how many times the floor can be sanded. What kind of finish and texture you want on the floor factors into how deep you will re-sand the floor during refinishing. A number of our reclaimed wood floors are sold with an original texture that shows the old saw marks and character in the floor, so most likely you won`t want to sand this out. As a rule of thumb, the thicker the wear layer then the longer the floor will last.
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.
