Question

Is it true that the redwood tree's bark is fire proof??

Answer 1

They are fire resistant but probably not quite fire proof.

"However, like sequoias, the bark, which may be up to 1 foot thick, contains tannin which provides protection against fire, insects, fungus, and diseases which might damage the tree. For example, there is no insect which can kill a redwood. The bark also gives the tree its distinctive "fluted" appearance."
