The Challenge of Cold/Cool Store Integrity
The structural integrity of cool and cold store panels and penetrations is crucial to operational efficiency.
Without adequate sealing, owners face severe financial and structural challenges:
- Energy and Cost Loss: Gaps in panels and around penetrations allow chilled air to escape easily. This forces the refrigeration system (chillers, cooling towers, evaporators) to run longer and harder, massively increasing the cost of electricity, refrigeration gas loss, maintenance, and equipment wear and tear.
- Structural Panel Damage: Escaping chilled air causes ice to form in the gaps. As ice expands, it accelerates panel damage, causing larger gaps, buckling, and further structural degradation.
- Vulnerability: Various panel penetrations (for pipes, cables, lighting, and access doors) must be sealed to stop the loss of refrigerated chilled air and prevent water leaks that cause icing on floors and walls.
Without specialised sealing, panel degradation accelerates due to ice expansion and moisture ingress, compromising temperature stability and forcing expensive replacement of panels and refrigeration gas lost from the system.

RepelCoat Solution: PUME-200 Panel Sealing Systems
FlowMatrix utilises RepelCoat PUME-200, a robust membrane coating system designed specifically for sealing and coating cool store panels, walls, and ceilings. This system bonds strongly while allowing flexibility to deal with the slight movement of the panels due to expansion and contraction.
Key Features and Benefits of RepelCoat PUME-200:
- Application Versatility: Applied to cool store panels, panel ceiling joints, cable/pipe penetrations, lighting fixtures, and loading dock seams..
- Panel Damage Elimination: Stops the formation and progression of expanding ice damage in panel joints.
- Refrigeration Retention: Stops the loss of refrigerated chilled air by reliably sealing panel seams and penetrations, reducing demands on the refrigeration system.
- Leak Prevention: Eliminates panel damage and stops water leaks that cause hazardous icing on floors and walls.
- Durability: The membrane bonds strongly and remains flexible to endure panel movement, drastically extending the service life of your panels for many years.
- Cost-Effectiveness: Sealing is a cost-effective solution that significantly reduces high operational costs related to energy usage and equipment maintenance.
Case Study: Reducing Operational Costs in Cold Storage
The Challenge: Refrigeration Loss and Panel Damage
Owners and operators of cool and cold storage facilities face significant operational costs due as refrigeration systems run hard to maintain set temperatures. When panel seals fail, chilled air easily escapes into the surrounding outside air, forcing the refrigeration system to work harder and increasing the cost of electricity, maintenance, and refrigeration gas. This energy loss causes two critical issues:
- Ice Damage: The escaping air causes ice to form in the panel gaps. As the ice expands, it accelerates panel damage, creating larger gaps and buckling, which further increases energy loss.
- Costly Inefficiency: The increasing panel damage and constant air loss mean the refrigeration system must run longer and harder, making system sealing critical to reducing operational costs.
The FlowMatrix Solution: RepelCoat Panel Sealing Systems
The FlowMatrix RepelCoat cool and cold store panel sealing system is utilised as a serious money saver for owners. The solution involves a specialised membrane system that effectively seals panels and critical penetrations.
The application process is meticulous:
- Preparation: The process involves professional cleaning of the surface, etching, and the application of a primer coat.
- Membrane System: The RepelCoat system is applied as a membrane system that bonds strongly onto the panels while retaining flexibility to deal with the slight movement of the panels due to expansion and contraction.
- Quality Assurance: FlowMatrix RepelCoat applicators are highly trained and experienced to deliver cost-saving panel sealing solutions that lock in chilled air and significantly reduce overall operational expenditure.
