Air conditioning systems insulated flexible duct noise reduction 5 inch acoustical flex duct

the acoustically insulated flexible ducts consists of a perforated aluminum/polyester laminate inner duct thermally and Acoustically insulated with 24kg/m325mm glass wool and is provided with aluminum foil laminated silver Outer jacket. A plastic barrier between the duct and the glass wool prevents the diffusion of glass wool particles.

Introduction

Inner duct of this acoustical thermal flexible duct is perforated AL foil duct, which is covered with tough polyester film and 25mm 16kg/m3Fiber glass wool. the barrier Is PE film or non-woven fabric. the outer jacket is AL foil duct enforced with Helix spiral wire. It is characteristic of preventing sound leaking from duct wall, Non combustible good resistance to acid, penetration and tear-resistance.
