Options:

•  Can be automatically operated whenever the appropriate side room exists

•  Slotted Curtain Doors - Are an excellent solution for areas where airflow through the door is required

•  Exterior or reverse roll doors - Are a practical alternative where interior headroom is limited or their positioning is required to protect glass windows and doors.
