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.
Claims17
A method for applying a hot melt adhesive to a mineral fiber insulation assembly, comprising the steps of:
- advancing a mineral fiber batt towards an adhesive applicator, the batt having at least two opposed surfaces and a thickness therebetween;
- disposing a hot melt adhesive from the applicator onto one of the surfaces of the batt;
- and
- moving the batt away from the adhesive applicator at a descending angle.
A method of producing a peel and stick insulation product, comprising the steps of:
- disposing a hot melt adhesive on a first surface of a fibrous mineral wool batt, wherein said batt includes said first surface, a second surface, and a thickness therebetween;
- and
- applying a vacuum to said second surface to draw a portion of said hot melt adhesive into said thickness of said batt.
