A door is provided, comprising one or more frames with grooves, one or more insert panel spacers comprising a foamed adhesive, and one or more door insert panels. Also, a method for centering a door panel is provided, comprising the steps of applying a foamed hot melt adhesive to the groove of a door frame component and inserting the door panel into the groove. Further, a system for centering a door panel is provided, comprising a hot foam melt adhesive, an apparatus for applying the hot foam melt adhesive to the groove of a door frame component, and an apparatus for inserting the door panel into the groove. The foamed hot melt adhesive may be formulated by aerating the hot foam with a gas, which may be an inert gas, such as nitrogen. Benefits of the invention include centering a door insert panel and allowing room for the panel to expand and contract with changes in moisture content of the panel.
