Protect values safely: ACO offers secure protection for your cellar and thus for your valuables. The cellar protection system, consisting of the ACO Therm® block with integrated, flood-proof* window, pressurised water-tight ACO Therm® light shaft as well as the ACO light shaft drainage and ACO backflow protection, ensures bright, dry and warm cellar rooms.
A flood-tight* ACO Therm® window is required when large amounts of surface water can enter the light shaft in addition to pressing groundwater.
