Revolving Entrance door or Double Airlock Door

A 2m x 2m revolving entrance door is fitted comprising of four rotating steel wings with acrylic viewing panels in each. This minimises air loss and maintains the slight internal pressure.

As an alternative to a revolving door, a double airlock door is available comprising of a pair of folding/sliding doors with acrylic viewing panels, at each end of a corridor. This is useful for wheelchair access or even for commercial vehicle access.

A number of 2m x 1.2m emergency doors fitted with viewing panels are provided, depending on the size of the Dome and local authority requirements.
