Fire protection in expansion joints and gaps

The fire protection cord FJ203 is a reliable solution for sealing expansion joints and gaps in fire compartments. Made of mineral rock wool, surrounded by a flexible glass fiber cover, it provides effective fire protection for masonry or concrete walls and ceilings. Its woven construction guarantees optimal filling of the gaps, minimizing the risk of fire and smoke spreading.

Easy installation and wide application

The FJ203 cord is distinguished by its simple installation – just press it into the gap, and its flexibility ensures a perfect fit. The possibility of one-sided baking further increases the convenience of installation. The product is designed for use in expansion joints with a gap width of 11 to 15 mm (with a tolerance of +20%), making it a universal choice for many construction projects. The cord works perfectly in both static gaps and expansion joints, ensuring safety and compliance with standards.

Construction features and compliance with standards

Its mineral rock wool is characterized by excellent resistance to high temperatures, and the glass fiber cover ensures durability and dimensional stability. The construction of the cord allows its effective use in various types of building partitions, providing comprehensive fire protection. Installing the cord only requires pressing it with a blunt tool to the edge of the gap – a simple solution for professionals and end users.
