Sonodec 25 GLX Combi
The Sonodec 25 GLX Combi consists of a perforated aluminum/polyester laminate inner duct, thermally and acoustically insulated with a glass wool layer and provided with an aluminum/copolymer laminate outer jacket. A plastic barrier between the inner duct and the glass wool prevents particle migration into the air stream. Both ends are taped to create ready-made connections.
