1. A method of making a self-stick insulation, comprising:
providing a piece of insulation product;
applying a water activated adhesive coating to a first major surface and a second major surface of the insulation product, the water activated adhesive coating comprising:
between about 30-55% by weight of solids of the adhesive coating of at least one of polystyrene-maleic anhydride (SMA) and polyacrylic acid (PAA);
between about 10-15% by weight of solids of the adhesive coating of an alcohol amine;
water; and
between about 30-60% by weight of solids of the adhesive coating of at least one of a polyvinyl alcohol and a starch; and
drying the adhesive coating on at least the first major surface to evaporate the water to form a dry adhesive coating layer on the surface.
