In this article we will be discussing several different categories of wood flooring. Solid wood flooring is one board with no glued up laminations; it is basically wood board that has been sized and profiled to a certain dimension. Engineered flooring has a on the top whatever species and texture you want, and this is glued to a plywood backer on the bottom. Engineered is still all wood but is made with multiple layers that are laminated for better stability and dimensional accuracy. Floors that we will not cover here are laminates or any composite products which are often not wood entirely through the plank or may be made with a photo printed surface. We also will not cover vinyl, carpet, stone, or tile.
With reclaimed material waste factor is a huge variable. How much effort does the manufacturer take to give you a 100% usable product? Poorly milled with very little defecting and culling done on a solid wood floor that costs $6/sf and has a 15% waste factor actually costs more than a similar product that is milled better costing $7/sf with a 2% waste factor. That extra wastes costs more in shipping and labor to defect. This is one of the hardest things to demonstrate to a customer that the face value costs doesn`t necessarily represent the actual raw material cost unless one is truly comparing identical quality and specified products.
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.
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.
