FIRE COMPARTMENTATION

Fire Doors: Passive Defense & Fire Containment

In high-rise commercial buildings and industrial manufacturing plants, fire compartmentation is vital for preventing the spread of fire, smoke, and toxic thermal gases. Certified fire doors act as essential passive fire barriers required by building codes to protect egress routes and grant occupants crucial time for safe evacuation.

New Type Engineering Co., Ltd. selects premium zinc-annealed galvanized steel door assemblies insulated with high-density rockwool core. All components comply strictly with international NFPA 80 inspection standards and building safety codes.

QUESTIONS & ANSWERS

Frequently Asked Questions

Why must fire-rated doors be equipped with an automatic self-closing device?

▼

Per NFPA 80 fire safety regulations, a fire door can only stop fire, heat, and toxic smoke when fully closed and latched. If left propped open, its fire containment ability is lost. Therefore, hydraulic door closers or spring hinges are mandatory to automatically pull the door shut after each passage.

What is the difference between a 2-hour and a 4-hour fire-rated door?

▼

The distinction lies in tested fire resistance duration under extreme heat. A 2-hour fire door is typical for exit stairwells, corridors, and commercial building corridors. A 3 to 4-hour fire door is required for industrial plants, chemical storage rooms, and main fire compartment walls dividing production facilities and warehouses.
