Self-stick insulation and methods

A method of making a self-adhesive insulation product comprising:

• providing a fibrous insulation blanket or board product, the fibrous insulation blanket or board product having:
• a length;
• a width;
• a thickness;
• a first major surface and a second major surface which each extend for the length and width of the fibrous insulation blanket or board product;
• and
• a facer coupled with the first major surface, the facer having a length approximately equal to the length of the fibrous insulation blanket or board product and a width that is greater than the width of the insulation blanket or board product so as to form flanges on opposing sides of the fibrous insulation blanket or board product when coupled with the first major surface;
• applying an adhesive to the flanges of the facer, the adhesive comprising an emulsion of a polymer material and water;
• passing the fibrous insulation blanket or board product and facer through an oven so as to evaporate the water of the adhesive applied to the flanges so that the adhesive forms a dry layer atop a surface of each flange, the adhesive being nonadherable when in the dry state and re-adherable upon an application of water;
• and
• rolling the fibrous insulation blanket or board product and facer to form a rolled insulation product.

A self-adhesive insulation product comprising:

• an elongated fibrous insulation blanket or board product, the fibrous insulation blanket or board product 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 or board product;
• and
• a coating of an adhesive applied to the first major surface of the fibrous insulation blanket or board product, the adhesive comprising an emulsion of a polymer material and water with the water evaporated such that the adhesive forms a dry layer atop the first major surface;
• wherein the adhesive is nonbondable when in the dry state, and wherein the adhesive is bondable upon the subsequent application of water.
