Fireproof cord FJ203 50mm for expansion joints, roll 25m FJ-0006

Fire protection in expansion joints – reliability and easy installation

The FJ203 firestop rope is an effective element protecting against the spread of fire in expansion joints and gaps in building structures. Made of mineral rock wool, surrounded by a flexible glass fiber cover, it provides optimal gap filling and creates a fire barrier. This rope is particularly recommended for use in masonry and concrete partitions, walls and ceilings.

Universal application and simple installation

The FJ203 rope is characterized by easy installation – simply press it into the gap, applying pressure with a blunt tool. The possibility of one-sided baking further facilitates the work of installers. The product is dedicated to expansion joints with a gap width of 31-40mm (with a tolerance of +20%), making it a universal solution on many construction sites. Thanks to its construction, the rope is ideal for places where there are gaps or expansion joints requiring fire protection sealing.

Safety confirmed by standards

The FJ203 firestop rope has been tested in accordance with EN 1366-4, which guarantees its high effectiveness in providing fire protection. The use of high-quality materials and precise production translate into the reliability and durability of the product. Remember to place the rope correctly inside the wall or ceiling – the surface of the rope should not protrude beyond the edges of the structure. Choosing the appropriate rope diameter for the gap width is crucial to ensure effective protection: for a width of 31-40 mm, a diameter of 50 mm is recommended, for 41-50 mm – 60 mm, for 51-60 mm – 70 mm, for 61-70 mm – 80 mm, for 71-80 mm – 90 mm, for 81-90 mm – 100 mm and for 91-100 mm – 120 mm.

A roll with a length of 25 m allows for securing a larger surface area, minimizing waste and making work on the construction site easier.
