Carpet is probably the most common floor covering that is used in residential homes. It comes in a wide variety of colors and textures. Carpet consists of woven fibers, which protrude upwards, glued or woven into a foam or jute backing. Often an underpad of pressed foam is installed below it or the backing can be integral with the carpet, adding to the softness and providing a much more comfortable surface for walking on. Carpet is installed by either gluing the carpet to the sub-floor, or the use of carpet tack around the perimeter. A good carpet will has a close weave, which will not show the backing material when separated. To reduce project costs, some contractors will opt to install a high quality underlay, with a low or medium quality carpet. This provides the soft surface, with equal durability, giving the homeowner the benefits of high quality carpet, at a reduced cost.
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.
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.
Undoubtedly you`ve seen wood floors where it seems that the edges or seams of boards joined together curl up or the width of a board creates a bow like upward arc in the middle. These are indications of moisture damage to a wooden floor. For example, there have even been instances where moisture damage caused floor boards to arc together to raise a full length sofa about three feet into the air. That was merely from the curl effect and strength of water on wooden floor boards. So, by all means do dry any spills to keep moisture and liquids away from your wooden floors.
