/11/09· In addition, vinyl jacketing often holds the water condensed at the cold pipe surface, producing a much greater threat of exterior pipe corrosion. The threat of insulation failure is greatest in smaller diameter piping due to its inherently lesser wall thickness coined with generally thinner insulation applied.
