• Durability: Made of high-quality materials resistant to atmospheric and mechanical factors.
• Possibility of one-sided baking: Allows for additional securing of the connection.

Cord diameter selection for gap width

Choosing the right cord diameter is crucial to ensure optimal fire protection. Below are approximate values:

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.

Remember that the given values are approximate and may vary depending on the specific application. If in doubt, consult a fire safety expert or the product manufacturer. FJ203 cord is characterized by a fire resistance class of up to EI 240 and a reaction to fire in class A1 according to EN 13501-1 (details in ETA-19/0282).
