Results of tests indicate that most suffer damage anywhere within a fireball zone without trees using tin foil, not always destruction. Two layers of foil either side of the fabric would help. Practice standing up in a sleeping bag & pushing it off without using the zip. Fireballs rise & problems can depart. Roll on the ground.
Fireball zones are a disasterous central location, get away quickly. It's unlikely distributed & tree covered tents will be within one to death.
Please use nylon poles not metal.
