Abstract:
1. A method of making a self-adhesive insulation blanket comprising: providing an elongated fibrous insulation blanket, the fibrous insulation blanket having: a length; a width; a thickness; and a first major surface and a second major surface which each extend for the length and width of the fibrous insulation blanket; applying an adhesive to the first major surface of the fibrous insulation blanket, the adhesive comprising an emulsion of a polymer material and water; passing the fibrous insulation blanket or board product through an oven so as to evaporate the water of the adhesive such that the adhesive forms a dry layer atop the first major surface, the adhesive forming a polymer matrix atop the first major surface and being nonadherable when in the dry state and re-adherable upon a subsequent application of water; and rolling the fibrous insulation blanket to form a blanket roll.
