Quietflex has now put the Quiet in flex duct. QAS™ Acoustical Flex Duct from Quietflex reduces the overall noise associated with your system. By reducing the noise transmitted through the duct from the HVAC unit along with the noise generated by the air flow QAS™ Acoustical Flex Duct reduces the noise coming out of the register. The key technology is the perforated inner core which allows the noise to be absorbed by the thermal insulation. In addition, QAS features Johns Manville formaldehyde-free™ insulation which reduces the risk of formaldehyde exposure.
