A Flexible Protection System for Insulated Tanks

17/03/2026

Industrial storage tanks demand more than insulation alone. HankoFLEX® brings insulation, membrane protection and purpose-made detailing together in one integrated system for projects where moisture, condensation, CUI risk and long-term performance must all be considered.

Rigid protection can become the weak point

Tank insulation systems are often most vulnerable where the construction changes shape. Joints, terminations, studs, pipes, flanges, brackets and transitions all have to accommodate movement while continuing to keep moisture out.

HankoFLEX® uses a flexible membrane-based outer layer together with specially adapted PIB details around critical areas. This creates a more coherent system that can follow complex geometry and protect the insulation against moisture, weather, UV exposure and mechanical impact.

Before and after: HankoFLEX can be used in the renovation and membrane protection of industrial storage tanks where moisture resistance, weather protection and long-term performance are key requirements. 

When Moisture Threatens Performance

Moisture in and around tank insulation can reduce thermal performance, increase energy consumption and raise the risk of corrosion under insulation. In industrial environments, that can affect operation, maintenance, inspection and service life.

Tank insulation is therefore not only about controlling heat or cold. The system also needs to remain dry, sealed and accessible for inspection over time.

HankoFLEX® is designed to reduce the risk of moisture ingress by protecting the insulation build-up with a flexible, membrane-based outer layer.

A Complete System for Demanding Tank Projects

HankoFLEX® combines insulation, membrane protection, reinforcement, fastening and purpose-made details in one integrated system. The solution is adapted to the specific tank, operating conditions and technical requirements.

HankoFLEX®  is particularly relevant for projects requiring:

  • Energy efficiency and stable temperature control
  • Protection against moisture and weather
  • Reduced risk of corrosion under insulation
  • Flexible detailing around studs, pipes and flanges
  • Easier inspection and maintenance
  • Long service life in demanding environments
  • Project-specific design and documentation
HankoFLEX brings insulation, membrane protection and detailing together in one project-specific tank solution.

Flexible membrane protection around critical details 

On industrial tanks, the details are often the most demanding part of the system. Penetrations, terminations, flanges, pipe connections and brackets must all accommodate movement, moisture, temperature changes and mechanical stress.

HankoFLEX® combines flexible PIB-based details with a membrane-based outer finish, helping protect the insulation build-up where moisture and movement place the greatest demands on the system.

The result is a more integrated solution in which insulation, terminations and membrane protection are designed to work together.

From assessment to a complete solution

 HankoFLEX® is not an off-the-shelf product. It is a project-specific system adapted to the individual tank, operating conditions and technical requirements.

A typical HankoFLEX® process may include:

  • Project assessment and technical clarification
  • Measurement and inspection
  • System design and recommended build-up
  • Material preparation and custom detailing
  • Delivery and logistics
  • Installation of insulation and membrane
  • Quality control during installation
  • Final inspection
  • Documentation and handover

This structured approach makes it possible to address technical requirements, installation quality and operational reliability as part of one coordinated process.
