Energy Storage System Applications
Microporous thermal insulation plays a powerful role in advancing Energy Storage Systems (ESS), delivering wide-ranging benefits across environmental performance, cost efficiency, operational reliability, and workplace safety.
By reducing heat loss and improving thermal control, it helps unlock substantial energy savings while creating cooler, safer operating environments and streamlining system performance for long-term efficiency.
Energy Storage System (ESS) Applications Benefits
Microporous thermal insulation can deliver significant benefits in terms of environmental, economic, social and operational impacts in applications in the ESS industry.
Significant energy savings can be achieved, at the same time contributing to a safer workplace, cooler environments, with reduced maintenance, and providing operational efficiencies.
Key Applications and Benefits for Energy Storage Systems
Battery Modules
Products:
Siltherm Silthin>
(Delivered in customised sizing)
BENEFITS:
Silthin acts as a compression pad and absorbs the movement of the cells as they swell with age and during charge and discharge cycles, meaning it maintains consistent pressure and structural stability throughout the battery’s life.
This dual function – thermal barrier plus mechanical compliance – supports safer, denser, and more durable ESS designs. With classification to 1000 °C, UL94 V0 fire performance, and thicknesses starting at just 0.6 mm, Silthin enables high energy
density pack layouts while providing critical passive fire protection and extended reaction time in the event of a cell failure.
Battery Rack
Products:
Siltherm Board>
Siltherm Panel FP>
(Delivered in customised sizing)
BENEFITS:
Siltherm microporous insulation is integrated into battery racks to create a multi layered passive fire protection and thermal management architecture.
Panels are installed around the outer walls of the battery rack to create a fire rated enclosure. This enclosure helps contain heat, protect adjacent equipment, and maintain compliance with fire rating requirements.
Container
BENEFITS:
Siltherm’s microporous fire protection panels used as container insulation in an ESS system delivering a powerful combination of thermal, mechanical and safety advantages that directly support modern battery energy storage requirements.
Its microporous core provides extremely low thermal conductivity, meaning the container walls can resist and slow heat transfer during abnormal or thermal runaway events, buying valuable time for system shutdown and fire suppression measures.
Because the material is inorganic, non combustible, and thermally stable with no ageing effect, it maintains predictable performance over the full life of the ESS asset.
The rigid panel format – often supplied with a clean, durable glass cloth encapsulation makes it easy to handle, cut, and integrate into container linings, firewalls, and compartment partitions without adding unnecessary weight or thickness.
These characteristics help maximise usable internal volume, reduce overall system weight, and improve energy efficiency.
