MIA Flexible Duct

Flexible aluminium duct for final connections from rigid duct branches to ceiling diffusers. Available in standard (single-layer foil) and insulated (foil + mineral wool) versions. Insulated version prevents condensation in humid or air-conditioned spaces.

Key Features

Technical Highlights

Standard Flexible Duct

Single-layer aluminium foil with steel wire spiral reinforcement. Minimum bend radius 150 mm. Maximum extension 6 m per run. Use for short final connections of 0.5–2 m in dry ceiling voids.

Insulated Flexible Duct

25 mm mineral wool insulation around foil core. Prevents condensation on cold supply duct surface in humid climates. Required in basements and below-grade installations.

Installation Notes

Keep flexible runs as short as possible — maximum 2 m recommended. Each bend adds pressure loss equivalent to 1.5 m of straight duct. Secure with stainless band clamps at each connection point.
