SONODEC 250 - Acoustically and thermal insulated ducting

The SONODEC 250 series 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 Rvalue to be effected by humidity influences and avoid grow of fungus in the insulation wool.
