The ferrocement roof consists panels size 1.5mtrs.x1.2mtrs. approximately and ferrocement portal and purlins replacing AC sheets and structurals steel trusses and purlins. Unlike AC sheet Metal, FRP roof all the ferrocement panels are joined monolithically. There will be no
nuts and bolt arrangement as in the case of AC sheet Metal, FRP roofs. But ferrocement panels shall be connected to the purlins and portal by welding and in-situ vibrated cement
matrix application. Or Ferrocement mega tiles of size 1.5 x 1.2 mtr. or more are laid just like
Mangalore tiles with most effective interlocking arrangement to prevent rain water entry
below. There will be least heat transfer as compared to AC sheets etc. The space below the
roof shall be neat and clean since the steel trusses are eliminated. There will be far better
storage space below without obstruction.
