Smoke Vents
Smoke Vents
Specifications
Smoke hatches are essential solutions for evacuating smoke and hot gases in case of fire, contributing to the safety of people and property. At the same time, they can also fulfill additional functions — daily ventilation, roof access, or natural lighting. All hatches are designed according to EN 12101-2 standards and can be configured according to the specifics of the project.
Why Smoke Hatches
In case of fire, rapid smoke evacuation is essential for saving lives. Smoke hatches offer an efficient and automated solution for smoke extraction, but can also have additional functions: daily ventilation, technical roof access, and natural lighting. Thus, you invest in a versatile, certified product adaptable to any type of building — from industrial halls to residential buildings.
Tested Reliability
Smoke extraction hatches are tested at 1000 cycles (Re 1000), and those with dual role (smoke extraction + ventilation) at 10,000 cycles.
Fire and Weather Resistance
The hatches meet the requirements of EN 12101-2, with 30 min resistance at 300°C, withstand snow, wind, and low temperatures.
Natural Ventilation
Through chain motors or pneumatic systems, hatches can be opened in a controlled manner for daily airing.
Zenithal Lighting
Polycarbonate or glass domes allow natural light to enter, reducing the need for artificial lighting.
Smoke Vent Service and Maintenance
To function correctly in critical situations, smoke hatches must be checked periodically. KADRA teams offer complete maintenance, testing, calibration, and repair services for all types of hatches — electric or pneumatic. We ensure quick interventions and customized solutions according to the specifics of each project. Read more about service and maintenance for smoke hatches on the service and maintenance page.

Frequently asked questions
What are smoke vents and what are they used for?
Smoke vents are systems installed in a building’s roof that automatically evacuate smoke and hot gases in case of fire. Their role is to keep evacuation routes visible and reduce the internal temperature of the building.
Are smoke vents mandatory in a building?
The obligation to install smoke vents depends on the building’s purpose, area, and configuration, according to applicable fire safety regulations. Requirements are established during the design and approval phase of the construction.
What standard must smoke vents comply with?
Smoke vents must comply with the European standard EN 12101-2 for smoke and heat exhaust ventilation. This standard sets requirements for performance, resistance, and operation in fire situations.
Can smoke vents also be used for daily ventilation?
Yes. Smoke vents can have a dual role, being used for both smoke extraction in case of fire and natural ventilation of the building. Models designed for daily ventilation are tested for up to 10,000 opening and closing cycles.
Can smoke vents bring natural light into the building?
Yes. Vents equipped with polycarbonate or glass domes allow natural light to penetrate and can reduce the need for artificial lighting during the day.
In what types of buildings are smoke vents used?
Smoke vents are used in industrial halls, logistics warehouses, shopping centers, office buildings, residential buildings, and other constructions that require smoke evacuation systems in case of fire.
How often should smoke vents be checked?
Smoke vents must be checked periodically to ensure they function correctly in emergency situations. Checks include testing opening mechanisms, electrical or pneumatic systems, and control elements.
What is the lifespan of a smoke vent?
The lifespan depends on usage conditions and maintenance performed. Vents certified for smoke extraction are tested for a minimum of 1,000 operating cycles, while models also used for ventilation can be tested for up to 10,000 cycles.
