Abstract
A pipe insulation product including a core of insulating material and a laminate surrounding the core and bonded to the core. 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 porous media sheet, and a polymeric film sheet bonded together via an adhesive. The laminate may include a closure flap that is configured to adhesively seal opposite ends of the laminate together to form a cylindrical tube with the core enclosed therein. The closure flap may be configured to include a curl that provides a greater closure flap adhesive seal.
