Fire-resistant doors and windows are the most basic elements of passive fire protection equipment in all buildings. All products included in this performance criterion are evaluated and classified within the framework of the standards determined by the European Standards Committee and accepted by the Turkish Standards Institute. In general, classification designations express the character and duration of the product. A hinged door classified as “EI260” describes a door that does not allow flame to pass through the gap it closes for 60 minutes and provides heat insulation.

Ninz, which has single and double wings, with or without windows, and separate two-way testing and certification for each size, provides access to all certificates and manuals from its website with the number written on the metal label on the door.

Fire resistant doors have EN 1634-1 fire and EN 1634-3 smoke certifications.

The customization of the product culminates in NDD technology (Ninz Digital Decor), a trademark that allows the reproduction of any theme (words, images, logos) on the door leaf surface.
