The three-chamber system is designed to set up internal or external firewalls. NT 78EI allows to assembly double-wing outward opening or inward opening doors with different threshold solutions. The system uses thermal pads with a width of 35 mm. The structural depth of the frame and wings is 78 mm.
There is an easy assembly of accessories in the NT 78EI system, which greatly accelerates the formation of the structure. With the three chamber design and additional reinforcing elements, the system allows to assembly construction of large size.
