Abstract
A doorway interconnection and method of creating an airtight seal between two doorways includes a first temporary membrane creating an airtight seal on a first doorway and a second temporary membrane creating an airtight seal on a second doorway and a gasket between the two doorways, and vents and valves to place and remove a sterilizing fluid in the inter-doorway volume. Such a system may be used to attach a sterile modular building unit to a sterile facility without losing the sterility of either the facility or the module building unit. Access to the membranes may be from one direction only. The gasket may provide motion and sound isolation between. Additional elements limit relative motions between the first and second doorways.
