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.
Did you see a picture that you like and now you have the bug that you want that special floor? The good news is that it could probably be made for you, but before you go a long ways down the path of choosing which floor you want and requesting a display room full of samples, ask about some price ranges. There is a common misconception that since reclaimed wood is supposedly salvaged it should be cheaper than virgin wood floors. If you are buying a quality kiln dried and precision milled product, generally that is not the case. The only cost savings would be if you found some scraps or did some salvage work yourself, you might save some costs. For example you might find a gym floor or planks out of a barn hay loft that you want to nail down on your floor. The material might have been next to free, but how much time are you going to have in making it usable and pulling nails? Are the results what you want?
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.
Most commonly installed are interlocking sheathing panels. This type of sheathing is generally 5/8" thick, and manufactured as either plywood or aspenite (commonly referred to as "chipboard") in 4` x 8` sheets. The sheets come with the long edges designed to interlock with a tongue on one edge, and a grove on the opposing edge. They are installed by simply pushing or pounding the sheets together, and nailing or screwing them to the joist work, in the same manner as raw sheathing. It is often the cheapest to install.
