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.
