Fire resistant duct enclosures
Fire resistant duct enclosures :
When it comes to construction and engineering, safety is crucial, and that includes fire protection. It is essential to guarantee the protection of gas pipes, medical fluids, various pipelines and electrical cable trays. This is where GEOSTAFF fire-resistant duct enclosures come into their own.
Current standards :
EN 13501-2 / EN 13501-2 FIRE RESISTANT DUCT ENCLOSURES/ EIS
The solution for technical duct enclosures
GEOSTAFF offers great flexibility in its fire-resistant enclosure solutions, thanks to the use of:
-
GEOTEC®S boards: These boards, used for GEOTEC® ventilation and smoke extraction ducts, can also be used for fire-rated duct cladding. They offer exceptional fire resistance and proven durability and can also be used for specific applications such as the protection of carbon fiber plates.
-
GEOFLAM®F boards: like GEOFLAM® ventilation and smoke extraction ducts, these boards are the ideal choice for fire protection enclosures, especially in high-risk fire environments.
-
GEOFLAM® C – Light channels: are ideal for cross-sections up to 350 x 200 mm. Their light weight and ease of installation make them ideal for encasing fire-resistant shafts.
These fire-resistants channels are pre-molded elements made from a sophisticated combination of gypsum and fiberglass, representing the ultimate in passive fire protection. Each component has been selected for its unique properties, guaranteeing maximum resistance to fire.

Versatile functionality
Our GEOFLAM® C Light fire resistant channels are open U-shaped modules, making them extremely versatile. They are ideally suited to enclosing technical ducts, whether for gas pipes, medical fluids, various pipes or electrical cable trays. What’s more, they can withstand exposure to fire for an impressive 2 hours (EI 120).
Simple installation and a wide range of applications
In addition to their safety performance, GEOFLAM® C Light fire resistant channels are designed for quick and easy installation. Thanks to the dedicated cover, the elements can be closed with ease, and their glued assembly greatly facilitates the process, reducing labor costs and installation time.
Thanks to their design and strength, GEOFLAM® C Light channels are suitable for a multitude of environments: hospitals, hotels, high-rise buildings, office blocks, residences and many more. Their adaptability makes them the ideal solution for any project requiring high-quality passive fire protection.
Environmental commitment
Gypsum, the main component of GEOFLAM® C Light channels, combines durability with respect for the environment. By adopting this solution, you are choosing an eco-responsible material, while ensuring optimum protection for your structure..
