Description
To enhance durability and hygiene, an anti-migration barrier prevents insulation fibres from entering the airflow, while also improving acoustic performance, reducing cold bridges, and maintaining the thermal R-value in humid environments. Both ends come pre-taped for easy, airtight installation
Key Features
- Sound Attenuation – Functions as a built-in silencer to reduce fan and duct noise, with proven performance across mid-range frequencies
- Thermal Insulation – 25 mm thick glass wool layer (16 kg/m³) with an R-value of 0.65 m²·K/W, minimising heat loss and condensation.
- Durable Construction – Inner duct of alu/poly laminate, insulation barrier film, and aluminium outer jacket for strength and longevity.
- Hygienic Design – Anti-migration barrier prevents dust and fibre release into the airflow, helping to avoid mould growth.
- Certified & Safe – Complies with EN 13180 flexible ductwork standards; fire classified to BS476 Part 6, 7 & 20, NEN 6065/6066, and NF M1; MED Marine certified
- Operating Range – Suitable for –30 °C to +140 °C, air velocities up to 25 m/s, and pressures up to +2500 Pa
Available Size
- Sonodec 25 TRD – 127 mm × 0.5 m
