Wider flooring is considered plank flooring.
But the two types of flooring have distinct advantages and disadvantages. Solid-wood flooring is milled from solid pieces of oak, maple or other lumber. Edges and ends are square or tongue and groove. That's why laminated flooring can be glued with a special mastic to most substrates even below grade. And because laminated flooring adds limited thickness to substrates, it can be a good choice where a wood floor meets vinyl or carpet.
