Calcium Polished Ceiling Fire Insulation Board

  • Fire Fighting Air Duct

  • WT



Our company manufactures fire-resistant panels for fire ventilation ducts, which are constructed using magnesium oxide and are coated with steel plates on the surface.

Fire-rated duct systems play a crucial role in ensuring the safety of buildings during a fire. There are two main types of these duct systems: smoke extraction ducts and ventilation ducts.

Smoke extraction ducts are designed to remove smoke from buildings, allowing for the safe evacuation of occupants and aiding in firefighting efforts. They are commonly used in large spaces such as commercial buildings, office complexes, residential buildings, and car parks. Car parks with low ceilings pose a particular risk, as smoke can quickly fill the area, hindering evacuation. Similarly, high compartments are susceptible to smoke spreading, which poses challenges for fire protection engineers due to the reduced effectiveness of automatic sprinkler systems.

Fire-rated ductworks are used to ensure proper compartmentation during a fire. Specifically, fire-rated ventilation ducts prevent the spread of fire and heat between two compartments.
