The MB-118EI system is designed for constructing fire rated partitions with a fire resistance class of EI 120. Certified as non-fire spreading (NRO), it offers robust fire protection for both internal and external walls. The system is specifically engineered to integrate seamlessly with the MB-78EI door, allowing for shared components such as glazing beads, cooling inserts, expanding tapes, seals, and most accessories. This compatibility extends to production and installation processes, simplifying assembly and ensuring consistent performance.

The MB-118EI system is constructed using five-chamber insulated aluminum profiles, each with a depth of 118 mm. Fire insulation materials are embedded within the internal chambers and the spaces between them, providing effective thermal and fire barriers. The system also incorporates expanding tapes on the external surfaces, which activate under heat to enhance the structure’s fire resistance. Steel components join the profiles, further reinforcing the system’s integrity during fire exposure.

This advanced system supports a range of glazing units, panels, and similar substrates, accommodating thicknesses from 31–35 mm or 48–84 mm. Its symmetrical design ensures consistent fire resistance in the EI 120 class, regardless of whether the fire originates from the exterior or interior of the partition. This dual-direction resistance is a critical feature for ensuring safety in diverse fire scenarios.

A significant advantage of the MB-118EI system is its ability to incorporate MB-78EI doors into the partition structure. This feature enhances functionality by providing flexible solutions for access points while maintaining the fire-resistance rating of the overall system.

The MB-118EI system has been carefully tested and holds the ITB Technical Approval No. AT-15-9186/2013, verifying its compliance with stringent safety standards. This certification confirms its suitability for use in high-risk environments where fire safety is of utmost importance.

MB-118EI is a reliable choice for projects requiring EI 120 fire rated partitions and the ideal solution for architects and builders prioritizing safety and durability.
