It is difficult to imagine modern construction without the use of plywood, which thanks to Burnblock® fire-retardant impregnation can achieve a fire resistance class of B-s1;d0. We can find them in schools, hotels, stadiums, theaters, hospitals, shopping malls and airports all over the world. Fire-resistant plywood is also a valued material and eagerly used in transport.
Fire retardant wood materials are constantly finding new applications. We also meet them in other industries, including as a raw material for the production of furniture, floor composites or exhibition infrastructure.
Moreover, Burnblock is:
What we say is what we can document – and we are clear and open about what we cannot document.Our Corporate Social Responsibility >>

For materials used in railways, the EN 45545-2 standard applies, which specifies the requirements for reaction to fire for materials and components used in passenger land transport vehicles running on rails (wagons, locomotives, trams). Thanks to the Burnblock® fire-retardant impregnation, they can achieve fire resistance, thus increasing the safety of passengers.
