Description
The Sonodec 25 TRD Non-Woven is a high-performance flexible insulated duct and sound attenuator, engineered to provide both thermal insulation and noise reduction in air supply and extraction systems. Constructed with a hydrophobic non-woven polypropylene inner duct, surrounded by 25 mm thick, 16 kg/m³ glass wool insulation, and protected by an aluminium laminated outer jacket, it ensures durability, excellent airflow, and reduced sound transmission.
Both ends of the duct are pre-taped for ready-to-install connections, simplifying installation and ensuring airtight joints. Its lightweight yet robust construction makes it suitable for new builds, retrofit projects, and space-restricted areas.
Key Features
- Sound Attenuation – Acts as a flexible silencer, reducing fan and airflow noise in duct systems
- Thermal Insulation – 25 mm glass wool layer (R-value: 0.65 m²·K/W) limits heat loss and prevents condensation.
- Durable Construction – Non-woven polypropylene inner duct with aluminium laminate outer jacket.
- Hydrophobic Inner Duct – Repels moisture for long-term reliability.
- Certified Performance – Classified B-s1,d0 under EN 13501-1 fire safety standards; compliant with EN 13180 for flexible ducts
- Operating Range – Temperatures from –30 °C to +140 °C, pressures up to +2500 Pa, and air velocities up to 25 m/s.
- Easy Installation – Pre-taped ends allow quick and secure connections.
