Two door vertical chiller

In the glazing industry, double doors can refer to any doors with two independently opening leaves. This includes French doors, but normally if you hear an industry professional talking about double doors, they are speaking about a larger version of the classic French door.While single leaf doors are made up of a single door leaf or panel that opens and closes, double doors have two panels that open in the middle, giving you a wider opening. These two panels are sometimes separated by a mullion.
