Won't straw decompose?
Plowed into the ground, most straw takes six months to decompose. Rice straw, which has a high silica content, takes twice that time. Straw has been used as an insulating material for many centuries, and has been found in excellent condition in Egyptian tombs thousands of years old. If kept dry, straw will not degrade. It can be said, then, that the lifetime of straw in a building could be anywhere from three weeks to nine-thousand years, depending on how well the building is constructed and cared for.
