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.
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.
We personally do not care for prefinished flooring due to installation problems associated with it, so our product requires site applied finish. This means that your floor finish if site applied will be easier to sand and refinish than a prefinished floor. Also you do not have to deal with that micro bevel groove between each board that tends to fill up with dust and crumbs. Most prefinished hardwood floors really can`t be refinished easily. To sand it off means that the wear layer has to be thicker than the height of the nails and have room to sand off the micro bevel between boards; that amounts to a lot of sanding. You also will not be able to spot sand or touch up parts of the floor.
Wood strip flooring is one of the oldest types of flooring still popular in the modern age. It consists of wood strips, usually interlocking, which are either nailed or glued to the sub-floor. Often the strips will be prefinished, requiring no post applications of sealers or varnishes. This type of flooring is very labour intensive for installation, as well as being quite expensive to purchase. However, the results are a warm, durable floor surface, requiring little maintenance or upkeep. Wood strip flooring significantly adds to the strength of the support system, reducing the deflection ("bounce") and gives the floor a very solid feel to it.
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.
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?
