The MB-78EI system offers a transparent, fire rated wall solution known as muntin-free walls. This innovative design allows for the creation of internal partitions without visible vertical profiles separating the individual glass modules, while maintaining full fire resistance.

The space between the glass panes, measuring just 4 millimeters, is filled with fire-retardant materials, including intumescent compounds and fire-resistant silicone. These partitions can achieve heights of up to 3.6 meters and module widths up to 1.8 meters. Fire tests conducted by the Building Research Institute (ITB) included models with free edges, confirming that the system has no limitations on the overall length of the partition.

The MB-78EI muntin-free system provides excellent design and construction flexibility, allowing for the creation of expansive, transparent internal walls. This strategic zoning supports safe evacuation and provides critical protection during fire emergencies.

Key Features

• The system has been rigorously tested at ITB and certified in two fire-rating classes: EI30 and EI60. The joint width between glass modules is minimized to only 4 millimeters, delivering a nearly seamless appearance. The system supports maximum wall heights of 3.6 meters and single module widths of 1.8 meters, with no restriction on the total length of a wall.
• Its compatibility with tempered glass is significantly stronger and more impact-resistant than non-tempered alternatives, ensuring both safety and durability.

MB-78EI muntin-free system represents a premium solution for architects and designers looking to balance form and function in fire rated partition walls.
