A method is provided for forming a relatively thick, lightweight, nonwoven insulating mat. The method includes the steps of forming a relatively thin, relatively dense first outer layer by needle punching a first batt of glass fibers and forming a relatively thin, relatively dense second outer layer by needle punching a second batt of glass fibers. A relatively thicker, relatively less dense intermediate batt of glass fibers is fed between the first and second layers. Thereafter, the first layer, intermediate batt, and second layer are needle punched together to form a multi-layer mat having a first layer, middle layer, and second layer.
