After installation, the insulation is clad with an aluminum jacket to ASTM B-209 with a laminated 1 mil polyethylene moisture barrier on the tank side. Standard exterior jacket finish is embossed "stucco" pattern to minimize glare and resist minor damage. All tank connections are recessed and the ASME nameplate exposed. All seams are caulked with aluminum pigmented silicone for weather protection.

IMPORTANT: Minor shipping damage is more noticeable on jacketed tanks due to the uniform finish and the nature of the jacket. Extra lugs are installed on jacketed vessels for securing the tanks during shipment and they are normally palletized and shipped on a flat bed. Even so, minor cosmetic damage can occur and must be considered normal.
