Insulated flex duct DN250, length 10m, 25mm insulation

Insulated flexible ALU duct Ø250 mm (10 m, 25 mm insulation) – ideal for HVAC systems, ventilation with heat recovery, and air distribution. Reduces thermal losses, prevents condensation, and dampens noise in ductwork. The inner perforated layer enhances acoustic insulation, while the flexible design allows for easy installation even in tight spaces.
