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.
This shrinking action pulls the floor together, adding strength to the overall system. The advantages of this type of sub-floor are its strength and durability. One important note, homeowners are often disturbed by the small 1/4" wide gaps, generally left between the individual planks after the wood dries out. Although disturbing to see during construction, upon completion, the spaces are not noticeable, and really have no impact on the sub-floor components at all. Strip floors are designed to be interlocking, through lapping or spacing of joints.
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.
