Thermofin® original product is produced using the same process, machinery and materials that has made it so successful for the past 35 years. Semi-rigid corrugated easily bent metal duct that can be formed by hand into curves and small radius elbows. Spiral formed out of aluminum alloy with 30 deg strength angles between ribs, mechanically locked together with continuous knurled leak proof "Acme" lock. Crimped ends slides easily into plain end, ensuring smooth connections. Our design allows for better stretching and bending characteristics. This helps eliminate flattening on the outside radius of a bend thus preventing restricted airflow.
