This tech can protect houses during fires, earthquakes and hurricanes
A building material called a 3D cementitious sandwich panel is made of fire retardant foam sandwiched between two wire mesh faces. The two faces are connected with reinforcement wires that run through the foam and the whole thing is enveloped in concrete. If built properly, it's very strong, and can withstand high winds, earthquakes and even fires. A start-up called RSG 3-D wants to bring this technology to the masses in the U.S.
