Thermal insulation tank solutions for sprinkler tanks

Automatic fire sprinkler tanks are installed for two main reasons; property protection and/or life safety. In both cases an essential part of the system is the water supply.

Since the extinguishing water temperature is typically below the adjacent room temperatures, using thermal insulation on the walls, ceiling and possibly the bottom of the sprinkler tank helps protect the adjacent rooms from issues with condensation.

Thermal insulation can also help prevent moisture penetration on the walls and ceilings.

Since insulating materials are very sensitive to moisture penetration, using an insulating material that is both impermeable to water and vapor, pressure-resistant and dimensionally stable is highly-beneficial.


FOAMGLAS® insulation is available in multiple high load bearing grades that are designed to withstand the pressure of a tank filled with water.


Being closed-cell material, it also helps limit condensation issues that could impact other parts of the building. The A1 fire class rating provides resistance. FOAMGLAS® insulation will not support combustion.
