Fireproof cord FJ203 70mm for expansion joints, roll 20m FJ-0009

Fire-Resistant Expansion Joint Cord – Safety and Easy Installation

FJ203 fire-resistant cord is a reliable solution for sealing expansion joints and gaps in building structures, providing effective fire protection. Made of mineral rock wool, surrounded by flexible glass fibers, it is characterized by high temperature resistance and durability. This cord is particularly useful in places where maintaining the integrity of fire compartments is required in the event of a fire.

Properties and Application

This fire-resistant cord is designed to fill expansion gaps in masonry, concrete structures, walls and ceilings. Its flexible structure allows for easy adaptation to different shapes and sizes of gaps, ensuring a tight and effective seal. This minimizes the spread of fire and smoke, increasing the safety of the building and its users. FJ203 cord is used both in new construction and during renovations and modernizations of existing facilities.

• Fire protection: Provides an effective fire barrier, delaying the spread of fire.
• Easy installation: Braided construction makes it easy to push the cord into the gap, speeding up the installation process. One-sided heat-sealing option further simplifies installation.
• Versatility: Suitable for use in various types of building partitions – masonry, concrete, walls and ceilings.
• Durability: Made of high-quality materials resistant to weather conditions and mechanical damage.
• Compliance with standards: Tested in accordance with EN 1366-4, which confirms its effectiveness and safety.

Choosing the right cord diameter is crucial to ensure optimal protection. Below are the ranges of gap widths and corresponding cord diameters:

For a gap width of 5-10 mm, a cord diameter of 12 mm is recommended. For a gap width of 11-15 mm, a cord diameter of 20 mm is recommended. For a gap width of 16-20 mm, a cord diameter of 30 mm is recommended. For a gap width of 21-30 mm, a cord diameter of 40 mm is recommended. For a gap width of 31-40 mm, a cord diameter of 50 mm is recommended. For a gap width of 41-50 mm, a cord diameter of 60 mm is recommended. For a gap width of 51-60 mm, a cord diameter of 70 mm is recommended. For a gap width of 61-70 mm, a cord diameter of 80 mm is recommended. For a gap width of 71-80 mm, a cord diameter of 90 mm is recommended. For a gap width of 81-90 mm, a cord diameter of 100 mm is recommended. For a gap width of 91-100 mm, a cord diameter of 120 mm is recommended.

It is important to remember to place the cord correctly inside the wall or ceiling – the surface of the cord should not protrude beyond the edges of the structure. For larger gaps, it is recommended to use two layers of cord to increase the effectiveness of the seal. FJ203 cord is available in rolls of 20 meters in length, allowing for flexible adjustment of the amount of material to the needs of a specific project.
