Renewable can be referred to as a resource that can be replenished or reformed either naturally or by systemic recycling of used resources. Renewable is resource or source of energy that is replaced naturally or controlled carefully and can therefore be used without the risk of finishing it all (Oxford dictionary).
Engineered Hardwood Floors. Engineered hardwood floors are not solid hardwood. Only the top layer is finished real wood so that you get the look and feel of a hardwood floor. The bottom layer, or core, is made up of stacked layers of fiberboard or plywood.
Made using three to four layers of wood glued together, engineered hardwood is often more durable, more environmentally friendly and can stand up better to changes in humidity as well as unruly children. The material costs are about the same as traditional hardwood, but the installs are faster and cheaper.
