The ExpressHeader was developed to be a cost reducing, time saving, energy efficient window and door header for 3-1/2" and 5-1/2" construction. The ExpressHeader is a structural product manufactured with 1-1/4" APA approved LVL. Its foam core is an expanded polystyrene that helps eliminate unnecessary wood fiber. This allows you to utilize only what is needed structurally. website | Information Sheet
