We have a 6'x6' square duct with negative pressure crossing from one building to another with 14 inches (+/-) of differntial movement (7" each). The duct is not flexible enough to absorb these movemnts without the use of flexible/expansion joints. Any recommendations would be appreciated. Thank you.
