Malkowski Martech Marc-OK fire curtain
By dividing the building into smaller sections, fire curtains prevent the spread of fire and smoke. This is crucial for ensuring the safe evacuation of people and for protecting valuable assets.
The discreet design of the curtains means they take up minimal space when rolled up in the cassette. When a fire alarm is triggered, they close automatically and are activated without the need for manual operation.
The fire curtains are perfectly suited for a variety of applications, including:
- Distribution centers and warehouses
- Manufacturing facilities
- Parking structures
- Shopping centers and public buildings
Our solutions are developed in accordance with the strictest fire safety regulations and provide security in both new and existing buildings.
