Product Overview

SEMIFLEX is a flexible duct made of metal produced from aluminum or stainless-steel strips profiled in a corrugated form. Compared to general flexible ducts for air conditioning and ventilation (e.g.: aluminum foil or tarpaulin material laminated with a polyester film), it has excellent fire resistance and durability.
