What is their expected operating life?
This is difficult to answer as it depends on the environment in which they are installed and how well they have been installed and are looked after. Most of the materials we supply in the UK have a 10 year warranty so we would expect 10 years life as a minimum. The material is rugged and has been developed and made specifically for the job, it is very unlikely that the Fabric Duct is going to tear or come apart at the seams for many years after warranty has ended unless it is subject to abuse or hostile conditions we were not aware of.
