High duty sound absorbing 8 inch acoustic flexible ducting for VAV box

Acoustic flexible duct

DEC-CXIA is an insulated acoustic air Duct, manufactured by using a dead soft aluminum strip which is Perforated, spirally wound and mechanically joined together.  

the inner perforated duct is wrapped with a Thick fiberglass insulation and covered by a flame retardant, non-toxic Polyethylene vapour barrier.

this top-rated product uses a perforated Core with an open area of 20% to 25% to completely cushion sounds such as air Movement and duct vibrations.

Full range of flexible acoustic thermal Insulated ducting for preventing condensation and reducing noise when there's Temperature difference in airflow of ventilation system.
