Laminate flooring is an alternative to wood flooring that consists of a multi-layer composite of organic and synthetic materials that make it durable and affordable. Most laminate floors are made of three main layers, though some products may incorporate the fourth layer. Underlayment: An attached layer that helps seal out moisture and provides a more comfortable underfoot feel Base Layer: A high-density fiberboard or wood composite that gives the floor structure Image Layer: A photo-realistic layer that gives the floor its color and looks Wear Layer: A transparent layer that protects the floor from damage
