Abstract
Our unique process applies pressure sensitive hot melt adhesive to fiberglass insulation with improved adhesion to the insulation surface and the adjoining substrate. As opposed to the typical spray or bead extrusion methods, the preferred embodiment applies a ribbon of adhesive to the blanket and pulls it into the insulating glass with a vacuum. The adhesive penetrates the glass and becomes an integral part of the insulating blanket.
