Thermal performance & insulation
GRP provides significantly lower thermal conductivity than metallic tank materials, helping reduce heat transfer through the tank panels. Where additional thermal protection is required, SUNNIK GRP sectional tanks can be supplied with polyurethane insulation.
Low Thermal Conductivity
GRP has significantly lower thermal conductivity than steel, helping reduce heat transfer through the tank walls and limiting temperature changes in stored water.
Up to 240× Lower Thermal Conductivity
Optional Thermal Insulation
For applications requiring additional thermal protection, SUNNIK GRP panels can be supplied with polyurethane foam insulation to further reduce heat transfer and help maintain the temperature of stored water.
25 mm or 50 mm Polyurethane Insulation
