Ekland Wood offers thermally modified spruce and pine cladding with BURNBLOCK fire retardant which is certified Fire Class B, Bs1, d0 (s2), the highest Euroclass for combustible materials. BURNBLOCK is also classified as non-hazardous to health or the environment.
Fire protection is created to a fixed depth on all 6 sides of each board in a monitored vacuum chamber with a high temperature curing process. The certification is EN13501-1 for impregnation of wood against fire in an exterior environment without a protective paint layer.
The use of BURNBLOCK will not change the texture of the wood and the lifespan is estimated to be 30 years or longer. Impregnated thermo-wood will weather to a silver grey colour in the normal way unless treated to protect it from UV light.
BURNBLOCK fire retardant has been successfully tested by several accredited testing institutions: DBI and DTU in Denmark, RISE in Sweden, MPA in Germany, and BRE in England.
100% natural, non-toxic and PH neutral.
