Biohabitat houses meet the more strict standards for the fire protection safety. Thanks to their large mass, Biohabitat walls are not easily flammable.
In the event of fire, wood only becomes carbonised externally thus protecting the internal structure, unlike other materials such as steel or concrete, which collapse with the heat.
The absence of oxygen in the internal constituent layers of the wall means that this only burns externally. The wooden dowels inside do not burn and as such do not collapse, unlike the case with riveting systems.
Moreover, as the walls have absolutely no glues or synthetic substances, combustion of the external surface does not produce toxic gases.
