Traditional Czech window
and door manufacturer since 1994


A 3-chamber design system intended for internal or external firewalls. PONZIO® NT 78 EI line fire doors are made in different variants: single-casement or double-casement doors opening inwards or outwards and with different threshold designs. 25 mm thermal insulation inserts are used in the system. Owing to the 3-chamber structure and additional bracing elements, the fire doors are very stable systems that can be used in the manufacture of large structures. Like the majority of systems in the PONZIO® family, NT 78 EI is fully compatible with all the other PONZIO® aluminum systems.

The system wings fit perfectly. The system also offers many variant door casement solutions as well as the ability to using it within smoke-tight structures or within arch-shaped structures. The fire inserts are gypsum- or silicate-based.


The system has gained full-range fire resistance classification. A system for both internal and external fire walls made of aluminum profiles with a thermal insulating insert. Based on heating tests from both the internal and external sides, the system is rated EI 60, EI 45, EI 30 and EI 15. The system constitutes the building’s fire-isolating and fire-resistant component.
