Isn’t a straw bale home more likely to burn in the event of a fire?

The simple answer is no. Loose straw is very susceptible to catching on fire, though a tightly bound bale will smoulder, not ignite. Besides, straw bales are not left exposed to the elements but, rather, covered in 1.5 inches of plaster on both the interior and exterior, starving the bale of oxygen. Where there is not oxygen there can not be fire. Fire tests show that once a straw bale is encased in plaster, it is able to withstand an 1400 degree (F) open flame for more than an hour without any significant structural damage, a benchmark that demonstrates just how fire resistant straw bale homes are.
