GUTEX wood fibre insulation boards easily satisfy the applicable requirements specified by law.

GUTEX wood fibre insulation boards easily satisfy the applicable requirements specified by law. Fire protection requirements are defined either via the construction material classifications or fire rating. GUTEX insulation boards are rated B2 in the German construction materials classification system or E in the European class. Both are normal flammable ratings. Wood has the ability to create a protective coat of carbon in the event of fire. It prevents or delays the consumption and spread of fire.
Thanks to this ability, wood structures with F30-B to F90-B fire resistance ratings are possible. F30-B and F90-B are ratings according to the German fire resistance classification system. The number refers to the time (in minutes) before the fire burns through the structure, before the structure’s load bearing capacity is lost and before the temperature on the other side of the structure becomes excessive.
