KD PREMIUM DOOR MODELS

The purpose of a fire door is to prevent a fire spreading from one section to another and to enable the safe evacuation of people from the building.

Determining the classification of fire doors:

• Integrity (E): the ability of an element to prevent the passage of flames or hot gasses. When the element is exposed to fire, cracks or openings should not appear.
• Insulation (I): the ability of an element to prevent the excessive transmittance of heat by conduction. Elements must be manufactured from materials that are thermal insulators.
  - Insulation (I2): average increase in temperature is 140 °C or less;
  - maximum increase in temperature on leaf is 180 °C or less;
  - maximum increase in temperature on frame is 360 °C or less.
• Time in minutes (30, 60, 90, 120), representing the time the criteria are fulfilled during the fire resistance test in accordance with the curve of a standard fire.
