发帖数: 18 | 3 Per spec., Semi-Rigid Aluminum Duct Features: Various applications include
dryer venting, air conditioning, fresh air intakes, heating, and exhausting
This Class 0, non-combustible duct is constructed of a special aluminum
alloy that prevents corrosion and metal fatigue The machine fabrication
produces a continuous lock seam that permits the duct to be pulled open,
compressed, bent, and re-bent without developing leakage Can be used for
concealed venting and eliminates the need for elbows 8" x 8.
My contractor preferred semi-rigid rather than 90-Degree Round Adjustable
Elbow. I guess it's due to more flexible and less abortions if I understood
him correctly.

: why semi-rigid duct?
