post27,CP,
Some years ago the Blue Mountains west of Sydney experienced devastating bushfires but one local refused to surrender his house to the inferno.
He had constructed an insulated "brick-**** house" which allowed him to safely shelter from the passing inferno.
Once it had passed it allowed him to attend to "spot-fires" and glowing embers in the gutters, so he saved his property with reduced damage.
Give that a serious thought mate.

heers.
