    Malkowski Martech Marc-OK+ fire curtain

    • Malkowski Martech

    Fire rated curtains are designed to deliver fire compartmentation by subdividing a building into smaller sections to prevent the spread of fire and smoke, which is vital for the safety of occupants and the protection of assets. 

    They are engineered to look discreet by taking marginal space when they are rolled up in the box when open, and close automatically in the event of fire alarm.

    Ideal for various applications including distribution centers and warehouses, manufacturing plants, parking lots, shopping centers, these fabric based barriers are designed to comply with the strictest fire safety regulations.
