Sustainability in flooring is about more than just the surface material. It involves the sourcing of raw materials, the manufacturing process, and even the longevity of the product. Engineered wood flooring is composed of a top layer of real hardwood over a core made from layers of plywood or high-density fiberboard. This construction method uses far less solid hardwood than traditional planks, making it a more resource-efficient alternative. What gives sustainable engineered wood flooring its eco-friendly edge is the use of responsibly harvested wood and low-emission adhesives. Many high-quality options carry certifications from organizations like the Forest Stewardship Council (FSC), which ensure that the wood is sourced from forests managed with environmental and social responsibility in mind.
