Galvanised Insulated Shutters

Cronax Galvanised Insulated Motorised Rolling Shutters are designed to provide maximum security, thermal insulation, and noise reduction, making them the ideal solution for industrial, commercial, and warehousing facilities. Built from double-walled galvanised steel slats filled with high-density insulation material, these shutters offer superior strength while ensuring energy efficiency.

Insulated construction helps maintain indoor temperature, reduces heat transfer, and minimizes energy costs for air-conditioned or cold storage facilities. At the same time, it provides effective sound insulation, ensuring a quieter and more controlled working environment. Made from galvanised steel, the shutters offer excellent resistance against corrosion, impact, and harsh weather conditions. Their rigid structure enhances durability while providing robust protection against forced entry.
