Glazed Fire Doors

Cronax Glazed Fire Doors combine transparency, elegance, and uncompromising fire protection. Designed with high-performance fire-rated glass and robust steel or aluminium frames, these doors provide up to 120–180 minutes of certified resistance against flames and smoke. Depending on the application, we offer both fire-protective glazing, suitable for 30–90 minutes of protection against fire and smoke, and fire-resistive glazing, which extends to higher ratings while also blocking radiant heat—making it possible to incorporate larger glass panels without compromising safety.

Beyond safety, Cronax Glazed Fire Doors add aesthetic value by maintaining natural light flow and visibility between spaces. Available in single or double-glazed options with customizable finishes and slim-profile vision panels, they are an ideal choice for hospitals, corporate offices, malls, airports, and other public buildings where both safety and design matter.
