No-muntin walls

Our offer includes a solution for transparent fire protection walls based on system MB-78EI, i.e. so-called no-muntin walls. It enables construction of internal partitions with no visible vertical profiles separating individual wall modules, while retaining its full fire resistance. The break between the glass panes is only 4 mm wide and filled with fireproof, expanding material and non-combustible silicone. Silicone is available in three colour variants (black, grey and white). Fire partitions executed in this way can reach 3.6 m of height and the width of their modules can reach even 1.5 m. Fire tests conducted in the Building Research Institute covered the partition model with a so-called free edge, due to which there are no constraints on the maximum length of this type of walls.

The system of no-muntin walls MB-78EI enables easy design and arrangement of internal surfaces of partition walls. Owing to transparent modules, structures performed with the use of this system allow for optical enlargement of the building interior. At the same time the system ensures safety, enabling organisation of fire compartments in buildings and ensuring relevant conditions for evacuation of persons.

ADVANTAGES:

• solutions had been developed and examined by the Building Research Institute in two fire resistance classes: EI30 and EI60
• width of the break between modules is only 4 mm
• maximum height of walls is 3.6 m
• maximum width of a single module is 1.5 m
• there are no constraints on the maximum length of the wall,
• structures have been tested with tempered glass panes that are more durable and have a greater impact resistance than non-tampered glass panes
