Fire-rated sliding gates
The primary goal of fire-rated and smoke-rated openings is to protect lives, and their design, selection, application, and maintenance come with great responsibility. Therefore, fire-rated and smoke-rated openings, as well as their manufacturing, must meet a number of standards and legal requirements, and proof of compliance must be provided. Alongside these requirements, aesthetic and practical considerations can be taken into account.
Coolfire Ltd.’s expertise, product suitability, and reliability are supported by:
- Being pioneers in introducing aluminum-framed glazed fire-rated and smoke-rated openings in Hungary.
- Over 15 years of market experience.
- The successful application and maintenance of fire-rated openings in numerous buildings, ensuring durability and trouble-free usage.
Fire-rated sliding doors used for the closure of larger wall openings at fire compartment boundaries represent the first, proven, reliable, cost-effective solution. Despite their robust appearance and significant use of space next to the opening, they remain a popular door type. The automatic operation, mechanical closing capability, and the option to integrate an escape route door into the sliding leaf make the Coolfire Marc-P, PT, PR(d) fire-rated sliding doors a practical solution.
Coolfire Marc fire-rated sliding door types:
- P – single-leaf sliding
- PT – double-leaf, one-way telescopic sliding
- R – double-leaf, bi-directional sliding
- (d) – Door with integrated pedestrian access door
Coolfire Marc-P, PT, R(d) Fire-rated sliding doors with EI30, EI60, EI120 fire resistance, with pedestrian access (also suitable for escape routes)

Special custom solutions, properties:
Coolfire Marc-P, PT, R Fire-Rated Sliding Doors provide solutions for fire-rated closure of various openings. Key features include:
- Suitable for fire-rated closure of large openings
- Requires minimal space above the opening, around 200-300 mm depending on the model
- Significant side space required, which should be discussed during the design phase
- Several options are available for installations with limited space:
- The weight compartment can be placed on either side, depending on the site’s configuration
- In a double-leaf door with two-way sliding, two narrower door panels need space on each side
- A double-leaf telescopic door sliding in one direction halves the side space needed
- Heavy and difficult to conceal
- Can be suspended from the ceiling using specialized brackets, allowing pipes and electrical cables to pass above the door
- Remains open with a 24V magnet, closing mechanically by weight in case of a power outage
- Personnel access doors are available in each model, with widths of 900, 1000, 1100, or 1200 mm and a height of 2000 mm, threshold-free and panic-safe
- Approved for cleanroom installations
- Wind load resistance up to class 2, 3, or 4, maintaining properties in pressurized environments
- Includes Sa smoke resistance in addition to fire-rated features
Fire-rated sliding doors are intended solely for emergency fire closure. They are unsuitable as general-purpose doors for thermal insulation, sound insulation, draft, security, or asset protection. For these requirements, we recommend visiting the Fire-Rated Sectional and Roller Doors product page.
Although factory-painted, the appearance of the sliding doors is robust and cannot be concealed, with a significant side space required next to the opening. Due to its favorable price and minimal space needed above the opening, it is excellently suited for fire-rated closure of openings in parking garages, underground garages, logistics halls, warehouses, and industrial facilities.
On evacuation routes, a single-leaf door integrated into the sliding door panel provides a solution, eliminating the need for a separate opening for escape, unlike other types of products such as fire curtains (except for the Bach-EV EW type), fire-rated sectional doors, and fire-rated roller doors.
Fire- and smoke-rated sliding doors are not conventional doors!
They are designed for emergency fire closure, with the curtain always in a rolled-up position under normal conditions.
The structural design of the curtain greatly impacts its long-term durability and maximum fire resistance capability. A system with a C1 classification (10,000 opening and closing cycles) is recommended, as it withstands power outages, maintenance, and fire drills over many years of use.
Door Panel: Composed of panels with 60 mm/100 mm thickness, weighing 30 kg/40 kg per square meter, 400-1200 mm in width, filled with fire-rated mineral wool, and covered with 0.5-0.7 mm thick galvanized steel.
The door panel is reinforced by U-shaped edge ribs and vertical steel rods for rigidity.
In the closed position, the door panel aligns with a “labyrinth” type receiving post to prevent fire spread. Its width is 125 mm, and with a counterweight cabinet, it’s 260 mm.
Track Rail, Upper Guide: The smooth sliding motion is ensured by a well-balanced roller-carrier system on a horizontally fixed track rail. Industrial steel-bearing roller carriers are attached to the upper edge of the door panel with a steel base, while the track rail system is mounted to the ceiling or lintel. A steel sheet cover conceals the track rail system.
Counterweight-Equipped Closing System: Components include an electromagnet for holding the door open, counterweights, a 3 mm steel cable connecting the door panel with the counterweights, and rotating pulleys for cable guidance. In the event of fire, power failure, or fire alarm, the electromagnet releases, causing the counterweights to descend vertically, closing the door panel at a steady speed of 0.3 m/s. The weights are housed in a closed steel box, which can be installed on the opening or closing side, attached to the receiving post.
Surface: The structure’s cover is galvanized steel with RAL color coating. Standard colors: galvanized, RAL7035, RAL9010, RAL9002, with optional additional RAL color coatings.
Installation requires a minimum clearance of 295 mm height for the lintel, 100 mm for lintel mounting, and a maximum 1500 mm drop height.
Side clearance depends on the location of the counterweight cabinet; it’s typically installed on the closing side, with the following space requirements beside the wall opening:
285 mm on the closing side, opening side requires wall opening width + 420 mm (varies by type).
Detailed technical drawings and node details regarding placement options for door types are available in the Product Page library.
In selecting the receiving structures, the installation of fire-rated structures is only permitted for types specified in the approval based on measurement results.
Coolfire Marc-P, PT, R (d) EI sliding doors can be installed on:
- Concrete and brick walls, lintels
- Steel support structures with fire protection cladding/paint coating
Other, custom receiving or support structures may also be used, in which case a unique statement of technical and fire safety compliance is required.
For each application, the design of the load-bearing steel structure must be verified with structural calculations.
Mounting options:
- On the plane of the opening, requiring a concrete lintel
- Attached underneath a concrete ceiling
- Hanging from the ceiling with a steel bracket
- On the plane of a steel support structure
- On fire-rated gypsum board and sandwich panel walls, where the opening is reinforced with a steel support structure
