What are Intumescent Fire Dampers and How Do They Work?

Air movement in buildings plays a crucial role in maintaining a healthy environment for occupants. Our innovative Lorient LVH44 intumescent fire dampers combine the essential function of air ventilation with fire protection capabilities.

Constructed with a robust galvanized steel framework and reinforced slats containing intumescent material, these fire dampers allow free airflow during normal conditions. However, in the event of a fire outbreak, the intumescent material within the slats rapidly expands upon exposure to high temperatures. This expansion causes the slats to fuse together, forming a solid fire-resistant barrier that effectively restricts the spread of fire, hot smoke, and toxic gases.

Addressing Building Design Needs

Sub-dividing buildings into fire-resistant compartments is a recognised method to contain and limit the spread of fires. While creating standalone fire compartments is relatively straightforward, integrating passages for everyday use poses design challenges.

Ventilation Considerations

Proper ventilation is essential for maintaining air quality and comfort within buildings. However, ductwork – a common element of HVAC systems – can serve as a potential pathway for fire and harmful emissions during fire incidents.

To address this issue, the Lorient solution involves installing LVH44 intumescent fire dampers at critical points where ducts penetrate fire-resistant constructions. By incorporating these fire dampers, the spread of fire is effectively contained, and the passage of hot smoke and toxic gases is restricted – ensuring the safety and integrity of fire compartments.
