Flexi-Duct offers multi plane movements in a shorter
face-to-face dimension. The ability to accommodate axial,
lateral (in two planes), torsional and angular movements concurrently
is an inherent capability of the expansion joint design.
Flexi-Duct uses a wide variety of elastomers which
can withstand temperatures up to 1200ºF and are a practical
and economical expansion joint solution.
• Superior corrosion resistance
• High temperature and mechanical strength
• Large amount of movements
• Low loads
• Noise and vibration elimination
• While meeting mechanical requirements, the
membrane must perform in severe heat,
weather, and chemically hostile environments.
• Exceptionally strong reinforcing materials
allow thinner membranes to optimize flexing
capabilities.
• Superior coating adhesion resists
de-lamination
• Air Pollution and Fume Control.
