Acacia is a fire-resistant wood flooring alternative, thanks to its high density. However, this wood material is not fire-proof. Be sure not to confuse one of these terms with the other! Australian acacia is a tree that has had to adapt to the harsh environmental conditions on its native continent. Australia often faces naturally-occurring fires, which helped this tree family become more resistant to fire than other types of wood. Simultaneously, acacia trees have thrived under difficult conditions, growing even larger and wider. That’s why these trees are the perfect source for flooring, furniture, and more.
