The “tight-sealing/cold-insulated” CB double valve system has been developed to counter the formation of condensation or the heat bridge in living areas / to ensure that the cold air doesn’t even reach the living space when the valves are closed.
The insulating valve between
“hot and cold”
Tight-sealing – cold-insulated
Effectively prevents condensate and energy loss
