The full-contact floating roof is constructed from a series of connected aluminum honeycomb panels and is equipped with a continuous closure device (primary and secondary seals) between the tank shell and the roof edge. The aluminum honeycomb panels maintain full contact with the liquid surface, preventing product evaporation. This design significantly reduces emissions and evaporative losses, while also protecting the tank from corrosive or oxidizing elements by eliminating the vapor space found in fixed-roof storage tanks.
