The third variable is installation costs. Our engineered product has labor savings over our solid wood product because it is pre-sanded and milled to tighter tolerances. It is also prefilled in the holes and has next to zero waste. On the other hand you may have a little more in cost of gluing it down in addition to nails, but this is just a step in direction of better quality and peace of mind during the install.
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.
Interlocking floor tiles are also useful to those who might only want to make a temporary change to their floors. Traditional tiles require adhesive and caulking, which frequently results in damage to the underlying floor. Interlocking tiles do not usually require any adhesive at all and can be pulled up as needed. This allows for more versatility should the user decide to change their floor back or install a different set of interlocking floor tiles.
There are three main types of sub-flooring installed to cover and span the floor structure. It is over this that the finished floor will be placed. The sub-flooring types include raw sheathing, interlocking and strip. It is utilized not only to provide a surface for the interior finishes to be placed on, but also to prevent twisting or torque forces placed on the building. The sub-floor also allows load sharing within the joist framing system. Often the sub-flooring is glued to the joist work to eliminate creaking floors and to prevent the floor joists from turning.
