Is asbestos cement-based siding considered a fire-rated material and would suffice as a firewall?
This property had what appeared to be asbestos cement-based siding. They later attached a garage and left the material on the inside wall of the garage toward the house. The interior wall has a couple locations where the firewall is compromised. But if it wasn’t compromised and the asbestos cement-based siding was solid all along the interior wall, would you consider it an acceptable firewall separation?
