Fire-Rated French Balcony Railing / Fire-Rated Glass Parapet/
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.
Proprietary, externally mounted fire-resistant glass balustrade structure, which serves as a barrier against vertical facade fire spread when using Juliet balcony doors or floor-to-ceiling windows. A condition for its application is the existence of the prescribed fire protection band around the window/door unit (in accordance with the Fire Protection Guideline-TVMI).
Simple, cost-effective solution, providing the opportunity to create a brighter, more inviting space.
The Fire-Rated Windows product group also includes other solutions for façade fire spread-resistant openings.

The fire-rated glass railing can be used for vertical fire spread protection in multi-story buildings, most commonly in apartment buildings, at locations where floor-to-ceiling windows are essential for light and views, and where the fire protection is ensured by a structured frame. By aligning several glass panels side by side, it is possible to provide fire protection for larger window sections with greater width and surface area.
The structural frame of the fire-rated glass panels is a vertical steel U-profile welded to steel brackets fixed to the wall on both sides of the glass panel.
- The steel brackets should be fixed to the outer surface of the wall, before the insulation, according to drawings A, B, and C.
- For larger openings, it is possible to align multiple glass panels side by side using vertical steel columns between the glass panels, based on the Horizontal and Vertical elevation drawings.
- The fire protection strip must be insulated with a fire-resistant material (e.g., rock wool).
- The glass panels are installed after insulation and coloring.
- Vertical steel U profile: 40*25*2 mm, intermediate column 60*60*3 mm.
- Maximum glass panel size: CoolGlass Fire Parapet, 13 mm thick 1750×1100 mm, 17 mm thick 2250×1100 mm.
