A pipe insulation product including a core of insulating material and a roughly rectangular laminate. The core may include an outer surface; an inner surface; and a wall extending between the outer and inner surfaces. The laminate may include a foil or metallized polymeric film sheet, a scrim, a paper media sheet, and a polymeric film sheet bonded together via an adhesive. The laminate may include a closure flap that adhesively seals opposite ends of the laminate together to form a cylindrical tube with the core enclosed therein. The paper media sheet may be between the range of 20 and 40 pounds per 3000 square feet to provide greater closure flap seal integrity without significantly reducing one or more beneficial properties of the laminate.
