Know before you buy
The R8 rating indicates a high level of thermal resistance, which helps prevent heat loss or gain as air travels through the duct. This efficiency ensures your furnace or air conditioner doesn't have to work as hard to maintain your desired temperature.
Yes, the Quietflex 8-inch duct is designed to meet the performance requirements for both residential and commercial HVAC applications.
The metalized jacket is engineered to be durable and resistant to common environmental stressors found in attics and crawlspaces. However, it should still be handled with care during installation to avoid punctures or tears.
While flexible ducts are easier to route around obstacles, they perform best when installed with minimal bends and kinks. To maintain optimal airflow, ensure the duct is pulled taut and avoid sharp turns that could restrict air movement.
Yes, each bag contains a single 25-foot section of flexible ducting, which can be cut to your specific length requirements during installation.
