Insulation jacketing and lagseal protection
Insulation cladding leaks at seams, support legs, and penetrations, letting water reach the pipe and hide active corrosion under the lagging.
What is failing
Insulation cladding leaks at seams, support legs, and pipe penetrations. Rain and wash-down work in behind the jacket and sit against the pipe. The water hides under the lagging and feeds active CUI, so the corrosion runs unseen until an inspector pulls the cladding and finds the damage already done.
How AAS does it
AAS seals the cladding with a reinforced membrane at the seams and penetrations, then ties it into a weather-side coating. We use systems such as Belzona 3211 lagseal with 9321 reinforcement and weatherproofing topcoats. The work is cold-applied on site, with no hot work over the insulated line.
Typically applied with Belzona 3211, Belzona 9321, Belzona 5151, Belzona 5871, matched to the service conditions.
The jacket sheds water at every seam and penetration. CUI never gets started under the lagging, and the insulation stays dry and effective.
How AAS delivers it
