Abstract
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 layer, a scrim, a porous media sheet layer, and a polymeric film sheet layer bonded together via an adhesive. The polymeric film sheet layer may also include a closure flap that adhesively couples opposite ends of the laminate together to form a cylindrical tube with the core enclosed therein. A charge dissipator may be applied to the polymeric film sheet layer in an amount sufficient to reduce generation of a static charge on the laminate's exterior surface without affecting the closure flap's ability to adhesively couple the opposite ends of the laminate.
