Why Are Smoke Ventilation Hatches Important?
Smoke hatches play a critical role in fire safety within buildings. They:
– Efficiently extract smoke and hot gases during a fire
– Improve visibility in evacuation routes
– Reduce the risk of smoke inhalation
– Support the efforts of emergency services
– Protect the building’s structural integrity from overheating
They are particularly essential in residential buildings, stairwells, warehouses, and industrial premises.
How Are Smoke Hatches Activated?
– Automatically: via smoke detector or fire alarm system
– Manually: using a push button or emergency release
Note: Hatches in our product range are not activated by thermal fuses.
