According to one embodiment, a self-adhesive insulation product is provided. The self-adhesive insulation product includes an elongated 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. The self-adhesive insulation product also includes a coating of an adhesive applied to the first major surface of the fibrous insulation blanket. The adhesive includes an emulsion of a polymer material and water with the water evaporated so that the adhesive forms a dry layer atop the first major surface. The adhesive is nonbondable or nonadherable to other objects when in the dry state and is bondable or adherable to other objects upon the subsequent application of water.
