Other flexible hoses Sonodec 25

Description The SONODEC 25 consists of a perforated aluminum laminate inner duct thermally and acoustically insulated with glass wool and is provided with an aluminium laminated outer jacket. An anti-migration barrier between the duct and the insulation wool adds strength and prevents the diffusion of insulation particles, as well as the following functions: improves acoustical performance, avoids cold bridges, leakage, pressure loss, protecting the R-value to be effected by humidity influences and avoid grow of fungus in the insulation wool. The SONODEC 25 fulfills all the requirements and are classified as specified within EN 13180: Ventilation for buildings – Ductwork – Dimensions and mechanical requirements for flexible ducts.
