Movement Capabilities

Non-metalic ducting movements can be calculated on the design and maximum excursion temperatures. One unit of fabric expansion joint is able to handle combined axial. lateral, angular and torsional movements. The expansion joint are carefully placed to minimize the number of expansion joints required while absorbing all of the duct movements
