The Lux Alesbo Insulated is an acoustically insulated flexible duct designed for ventilation, heating, and cooling applications where thermal comfort and noise reduction are essential. Its micro-perforated inner duct provides effective sound attenuation, while the integrated polyester (PET) barrier prevents fibre diffusion, contributing to improved indoor air quality.

The glass wool insulation delivers balanced thermal and acoustic performance, complemented by a multi-layer construction that enhances reliability and durability. With an A1 fire reaction classification, it is suitable for more demanding applications and is available with different thermal resistance levels (RA 2, R6, and R8).

Designed for demanding operating conditions, it performs within a temperature range of -30°C to +140°C and supports air velocities of up to 30 m/s, ensuring consistent, quiet, and reliable performance over time.
