Quietflo Components


Quietflo ducting is amongst the best on the market and is fully tested to comply with Australian and International Standards AS 4254 and UL 181. These Standards test the fire rating, strength and durability of ducting to allow for a safer and cleaner duct environment.

Quietflo ducting is comprised of:

Outer Sleeve
The aluminised coating is a highly reflective outer barrier which reflects light and heat away from the duct, thereby increasing the duct's insulation properties.

Polyester Insulation
R0.6 25mm or R1.0 50mm

Tough Inner Lining
The heart of our duct is our exclusive Polyethylene inner lining. At 75 microns, it is almost three times thicker than the industry standard of around 25 microns for glued MYLAR duct.

Reinforced with spring steel BHP wire, our inner lining will always hold its shape, unlike some other duct which is manufactured using mild steel wire.

Ducting Photo 

Superior acoustic qualities. Our duct has been tested to AS 1277-1983, and has been shown to absorb noise and reduce some sounds by as much as 75% when compared to standard duct.
