Abstract
A vapor barrier laminate for use in insulation applications as a facing material. A fiberglass yarn or scrim is positioned between layers of kraft paper. An aluminum foil is adhered directly to the outer kraft paper layer. The paper to foil bond and the paper to paper bond are accomplished with a flame retardant adhesive. The resulting heavier and thicker laminate provides increased rigidity, a smoother outer surface for better abrasion resistance, and a greater tensile strength. Use of the laminate in duct board facing improves the strength of the duct board while facilitating tape adherence for sealing gaps between board sections.
