There are three different types of aluminum composite panels include engineer wood, aluminum and fiberglass. Engineered wood composite panels are formed with compressed wood fibers combined with epoxy resin. Wood composite panels are used for many construction structures and have decreased consumer demand for plywood. They are used to provide strength and endurance to wall framing or assembly floors and roofs. Aluminum panels also referred to as “sandwich panels” and are mainly used in aircraft and automotive industries to develop lightweight vehicles.
