A method and configuration are provided for joining a facing having periodic rows of perforations to insulation. Adhesive is applied to the perforated facing in a periodic pattern. The facing is joined to the insulation. The periodic pattern is offset from the rows of perforations, or the period of the pattern is different from the period of the rows of perforations, so that at least some of the perforations do not coincide with any of the pattern of adhesive.
