Fire-rated curtains (E, EW, EI with water)
The primary goal of fire- and smoke-rated doors and windows is the protection of life, and their design, selection, installation, and maintenance come with great responsibility. Therefore, fire- and smoke-rated doors and windows, as well as their manufacturing, must comply with numerous standards and legal requirements, and their certification must be ensured. In addition to their existence, other aesthetic and practical considerations can be taken into account.
The expertise, suitability, and reliability of Coolfire Ltd. products are supported by:
- Pioneers in introducing aluminum-framed glazed fire- and smoke-rated doors and windows in the domestic market.
- Over 15 years of experience gained during their market presence.
- Numerous buildings where fire-rated doors and windows have been applied and their trouble-free use, durability, and maintenance.
One of the greatest achievements in the fire protection sector of the construction industry in recent years is the introduction of fire- and smoke-rated curtain systems, which offer new possibilities for how buildings can be designed from the planning stage.
Large surface fire and smoke compartment walls can be replaced by automatic fire-rated curtains, increasing the interior space thanks to the curtains remaining open. They only close in the event of a fire.
Their small space requirements allow for hidden installation above the suspended ceiling, preserving the aesthetic appearance of the interior spaces.
An economical solution.

Special custom solutions, properties:
The Coolfire fire-rated color product range provides solutions for every installation position, meeting both technical and aesthetic requirements.
- If the fire protection requirement is E (integrity), the Coolfire-EGRESS Fire (E) can be applied on escape routes up to 120 minutes performance.
- The Coolfire – Fire (EW) can be used in many cases as a facade vertical/horizontal fire spread barrier:
– Attached to the inner/outer surface of facade windows
– Connected to the inner surface of the end sections of curtain walls - The Coolfire – Fire Z (E, EW) and Coolfire – SuperFire Z (EI) vertical automatic fire-rated curtains open in a folded accordion form on the sides. When open, they are gathered in a roof box installed above the suspended ceiling, fitting seamlessly to the underside of the ceiling. Their height can be up to 5 meters.
Due to their unique properties, they are suitable for custom closures with multiple continuous sides:
– Right angle 2-sided corner closure
– U-shaped 3-sided closure
– Regular square enclosed shape - The horizontal Coolfire – Fire H (E, EW) fire-rated curtains can be used independently in interior spaces or to prevent fire spread on facades, under glass ceilings. They allow for ceiling penetrations while maintaining the advantages of open ceilings.
- Coolfire – SuperFire (EI) and Coolfire – SuperFire Z (EI) 2-hour fire-resistant curtains achieve their fire protection properties using an open sprinkler water cooling system. The sprinklers are concealed in the curtain’s roof box structure and are part of the curtain assembly. Their application requires an adequate amount of water, fire water, and/or sprinkler system, and the cost calculation must take these requirements into account.
- The “dry” fire-rated curtain family, the Coolfire EI-Marc, fulfills the EI requirement without water demand. Detailed technical descriptions can be found on the Fire-Rated Curtains Without Water Cooling product page.
The fire-rated curtains are designed only for fire closure purposes. They cannot be used as “gates,” and the wall opening cannot be sealed for thermal insulation, soundproofing, draft, security, or property protection purposes. For such requirements, we recommend the Fire-Rated Sectional and Rolling Doors product page.
Due to the large-area curtain design, the roof box containing the necessary accessories for the curtain’s opening (rolling) mechanism (shaft, tube motor), which can be hidden in the suspended ceiling space, its use is recommended for all types of buildings where the prevention of fire and smoke spread is required.
Exception:
Fire and smoke barriers are not gates!
According to the tests based on MSZ EN 1191:2013, MSZ EN 14600:2005, MSZ EN 4102-18:1991, their self-closing capability is C1 (10,000 open-close cycles), and their mechanical stability and operational reliability class is C1.
They are intended for fire closure only, and in their default state, the curtain is always in a rolled-up position.
The curtain is made of fiberglass material, with both sides of the EW type covered with aluminum foil and reinforced with stainless steel braid, mounted on a 78 mm diameter shaft. The entire system is driven by one or more 24 V tube motors, depending on the size, and its operation is controlled by a control system. The operator panel requires 230 V input and 24 V output voltage. The uninterruptible power supply (UPS) system ensures the connection to the fire alarm center and the curtain operation through the emergency opening buttons in case of a power failure, for up to 6 hours. According to regulations, emergency opening buttons must be placed on both sides of the curtain.
The accessories, roof box cover, 120 mm wide vertical guide rails, and the lower stiffening rod are made of galvanized steel, with optional RAL color coating.
The roof box can be mounted in several ways: from below on the ceiling/beam, suspended from the ceiling using steel brackets, or mounted on the side of the beam.
The size of the roof box changes depending on the height of the structure.
The width of the structure can be increased by overlapping the curtain material. In this case, two parallel-mounted tube motors, installed on two parallel shafts, perform the opening. Depending on the available space, the shafts can be placed next to each other or stacked vertically.
In the event of a power failure or fire signal, the closure occurs gravitationally.
When selecting the receiving structures, the installation of fire-rated structures is only permitted based on measurement results and the specified types in the approval.
The Coolfire Fire and Superfire type fire- and smoke-rated structures can be installed on:
- Concrete or brick walls, lintels
- Steel load-bearing structures with fire protection cladding/paint coating
Other custom receiving or load-bearing structures can also be used; in such cases, the technical and fire protection compliance must be verified with a special statement.
For each application, the design of the load-bearing steel structure must be verified by static calculations.
Installation options:
- Mounted to the plane of the opening, with a concrete lintel required
- Mounted from below to a concrete ceiling
- Suspended from the ceiling using steel brackets
- Mounted to the plane of a steel load-bearing structure
- Mounted on drywall and sandwich panel walls, with the opening reinforced by a steel load-bearing structure
