Acoustic Duct

UNILOK FR1 thermally and acoustically insulated fi re retardant ducting is a fl exible duct manufactured “tough” for consumer and installer peace of mind. UNILOK FR1 acoustic ducting is also manufactured “whisper quiet”. Unlike other types of fl exible duct, UNILOK FR1 has an outer steel rib that ensures the products integrity and correct diameter, even in the tightest bends. Due to its steel rib, it is not prone to glue failure or fatigue (sagging or ovalisation) from vibration with age like plastic ribbed or non-ribbed glued duct.
