In-Room Energy and Intruders Where They Belong
High-speed operation controls the air exchange so less energy is required to maintain building temperature. The
door’s aluminum slats have a durable rubber membrane covering their connecting hinges, to contain heating/
cooling energy and preventing air infiltration. This tight seal stops dust pollution, drafts and inclement weather.
This same design also provides an effective barrier against unauthorized personnel. The door’s fast speed
confines access to traffic that belongs in the building.
