Knauf Insulation is now (to our knowledge) the FIRST to make available a formaldehyde-free duct liner for use to internally line metal ducts. And most importantly.. ”Certified for indoor air quality as a low emitting product by The GREENGUARD Environmental Institute to both the GREENGUARD Certification Program^SM  and the more stringent GREENGUARD Children and Schools^SM standard.”

We knew that Johns Manville had a low formaldehyde duct liner, and a formaldehyde free external duct wrap.  They also now have a formaldehyde free duct board.  So far they do not have it in duct liner.

Their formaldehyde free duct board used to make ducts.

It is obvious then that duct liner is on the way.
