There area a lot of what I consider to be false claims of fire resistance in the ICF industry. Many products are made of virgin plastic foams which simply melt in high heat. For this reason I have primarily focused on cementicious type ICF blocks with recycled foam content. These are well tested at four hours of 2,000 degree flame.
Assume the best and ask questions.
