Swiss Krono simplifies fire safety in construction with OSB/3 Stop Fire EN300

 Wednesday, September 17, 2025

The SWISS KRONO OSB/3 Stop Fire EN300 is the ideal material to meet the highest standards of wood-based fire safety and building performance.

At Université Paris-Saclay, this cutting-edge solution was chosen for its outstanding fire-resistant properties, formaldehyde-free bonding, and water-resistant ContiFinish® surface, making it the perfect choice for interior construction. Choosing SWISS KRONO OSB/3 Stop Fire EN300 means investing in high-performance, eco-conscious wood materials that ensure safety and durability in every project.

SWISS KRONO OSB/3 stop fire EN300 is an enhancement of SWISS KRONO OSB/3, the well-known high-performance staple. Like it, the flame-retardant version is CE-certified under DIN EN 13986 and an ideal engineered wood product for loadbearing and reinforcing applications. The boards are completely impregnated with flame retardant to slow or prevent fires from starting, also after being worked and even at their corners and edges. This is a major advantage over other engineered wood products which merely have coated surfaces.

Characteristics:

• When exposed to flame, it chars to forms a fire-inhibiting layer
• It reliably extinguishes without smouldering or continuously glowing
• As the strands used to make it are treated as well, the edges of boards are also flame-retardant
• It is as easy to saw, cut and otherwise work as standard OSB
