Fire-rated Curtains
(EI dry)
The primary goal of fire and smoke-resistant doors is the protection of life, and their planning, selection, application, and maintenance carry great responsibility. Therefore, fire and smoke-resistant doors, as well as their manufacturing, must meet numerous requirements set by standards and laws, and these must be verified. In addition to their existence, other aesthetic and practical considerations may be taken into account.
The expertise, suitability, and reliability of Coolfire Ltd.’s products are supported by:
- Pioneers in the introduction of aluminum profile glazed fire and smoke-resistant doors in the domestic market
- Experience gained during more than 15 years of market presence
- The use of fire-resistant doors in numerous buildings and their trouble-free operation, durability, and maintenance
The greatest achievement in the construction industry’s fire protection sector in recent years has been the appearance of fire and smoke-resistant curtain systems, offering new possibilities for building design already in the planning phase.
Large-area smoke and fire compartment walls can be replaced with automatic fire-resistant curtains, increasing the interior spaces thanks to the curtains’ open position. They only close in the event of a fire.
Their small space requirement allows for their installation above or within a suspended ceiling in a hidden form, preserving the visual appearance of the interior spaces.
The latest curtain type developed, the Coolfire Marc-OK EI fire curtain, which does not require water cooling, can replace the more complex open sprinkler water-cooled EI curtains, saving the cost of expanding the sprinkler system and increasing the water volume. It is an excellent solution in buildings where no sprinkler system is installed, or there is insufficient fire water.

Special custom solutions, properties:
Coolfire Marc-OK EI fire-rated curtain without water cooling, a newly developed fire-resistant structure, adapted to modern architectural needs, eliminating the disadvantages of structures with the same fire-resistance rating.
- Suitable for fire-sealing extra large openings
- Requires minimal lateral and top space
- Can be installed in a hidden way in the space above the suspended ceiling
- Tested and can be installed in cleanroom environments
- Wind load resistance class 2, can also be used in pressurized rooms
- Can be used as a vertical/horizontal fire barrier on façades in many cases:
- Mounted to the interior/exterior surface of facade windows
- Connected to the interior surface of the outermost parts of curtain walls and frame-filled glass walls
- Fire-sealing of wall penetrations in Kovejor roller conveyor systems in line with their control system
- Meets EI30, EI60, EI90, EI120 requirements “dry”, without water demand
The fire-rated curtains are designed for closure in the event of a fire. They are not suitable for use as “gates,” and the wall opening cannot be closed for thermal insulation, sound insulation, drafts, or security and asset protection purposes. For such needs, we recommend the Fire-rated sectional and roller doors product page.
The Coolfire Marc-OK EI fire-rated curtains, thanks to their design and the ceiling box containing the necessary components for curtain opening (rolling) such as the axle and tube motor, can be hidden in the space above the suspended ceiling. This makes them suitable for use in all types of buildings where the prevention of fire and smoke spread is necessary.
They are not suitable for use on escape routes, except where a panic function door can be installed next to the curtain.
Fire- and smoke-rated curtains are not gates!
They are designed for fire safety closure, and in their default state, the curtain is always in a rolled-up position.
The long-term durability and maximum fire protection capacity of the curtain are greatly influenced by the structural design. A structure with C1 (10,000 opening/closing cycles) properties is recommended, as it will be used for many years, even during power outages, maintenance, and fire tests.
Curtain material: Three-layer, specially designed fire-resistant fabric, fastened with double thread stitching, 9-18 mm thick, flexible, RAL7035 color.
Counterweight: A 30 mm diameter, hidden steel rod ensures gravitational closure by stretching the lower edge of the curtain in the width of the opening.
Vertical guide rails: 120 mm wide, 80 mm thick, steel columns with fire protection coating.
Axle: The curtain opens by winding around an axle fixed above the opening on brackets.
Ceiling box: A 0.7 mm steel sheet covering that hides the axle and brackets.
Surface: The surface of the ceiling box and the material of the vertical guide rails are made of galvanized steel with an RAL color coating. Standard colors: galvanized, RAL7035, RAL9010, RAL9002, optionally other RAL color coatings.
Drive (motor): Tube motor placed in the axle – 24V for small curtains, 230V for larger curtains, or axle-end drive 230V – 400V for extra large curtains.
Control unit: Connection to fire alarm system or own smoke and/or fire detection system, uninterruptible power supply – ensures the connection to the fire alarm center and the operation of the curtain through the use of emergency opening buttons during a power failure.
For fire compartment boundaries, the curtain and the fire-rated door without a passage both provide the option for opening (emergency opening/curtain opening button) on both sides of the fire compartment boundary.
The size of the ceiling box depends on the height of the structure.
In the event of a power failure or fire alarm, the closure happens by gravity.
The installation of the fire-resistant structure is only allowed based on measurement results and for the types specified in the approval.
The Coolfire Marc-OK EI type curtains can be installed on:
- Concrete, brick walls, and lintels
- Steel load-bearing structures with fire-resistant coating/paint
Other, custom receiving or supporting structures can also be used, but in such cases, technical and fire protection compliance must be confirmed with a custom statement.
For each application, the load-bearing steel structure must be verified through static calculations.
Installation options:
- Mounted on the plane of the opening, requiring a concrete lintel
- Mounted on a concrete ceiling from below
- Suspended from the ceiling using a steel bracket
- Mounted on the plane of a steel supporting structure
- Mounted on fire-resistant drywall and sandwich panel walls, where the opening is reinforced by a steel supporting structure
