Abstract: Natural wood sandwiched engineered flooring utilizes all natural wood as the raw material which is made into several components which are combined to make this product. The components are a single or multilayer top veneer bottom or base layer and a middle layer. The four sides of the natural wood sandwiched engineered flooring strip consist of either a tongue and a groove or an interlocking system. The middle layer consists of two parallel solid wood strips, and located perpendicular to and between the parallel solid wood strips are small pieces of soft wood, which are glued together. The small soft wood pieces can be of fast growing soft wood, and as such saves treasured hardwood lumber. The production cost of the raw material is much lower than other types of engineered flooring. Further, an enhanced stabilization of the hardwood flooring is provided which is more suitable for radiant heat.
