System description
The three chamber system is designed to perform internal or external firewalls. NT 78EI allows you to perform a double-wing doors and opening to the outside and inside of different solutions threshold. The system uses thermal pads with a width of 35 mm. The structural depth of the frame and wings is 78 mm. System construction allows easy accessories assembling which greatly accelerates the formation of the structure. With the three chamber design and additional reinforcing elements, the system allows you to perform the construction of large size.
