If kept dry, straw insulation can last over a hundred years. There are several churches and houses built with straw as early as 1928 still standing with straw inspected to be in the same condition when it was installed. (1)

We protect exteriors of our buildings with high performance water-resistant barriers (Henry© Blueskin) and a rain screen. Exteriors are finished with either a rain screen and conventional siding or plaster, for added layers of moisture protection. Just like any home, you don't want to keep any part of the building exposed to standing water for any period of time. With a toe-up, interior, and exterior protection, Building Integrity's straw bale panels perform very well against water and other threats to the home. (2)

Strawbale construction is no more attractive to pests than any other building material.  Straw is different from hay in that there are no seed heads in the bales. There are no nutrients in the walls for animals to be attracted to, straw filled walls are very similar in many ways to chopped up cellulose insulation. (1)

Fire requires three elements (the so-called Fire Triangle) in order to burn.  These are fuel, oxygen, and heat.  Compressed straw contains very little oxygen, and thus can burn only slowly.  Straw is very similar in composition to cellulose. With the options of plaster or drywall, straw bale panels may withstand 2-3 hours of direct flame before igniting. This is very similar if not better than most stick frame homes with drywall. (1)
