Zusammenfassung: | Disclosed herein is a flexible thermally insulating duct liner comprising a fibrous thermal insulation layer having an organic fibrous layer having an open structure bonded to its working face, the working face being thereafter coated with a flame retardant vinyl polymer containing coating. The duct liner of the present invention has an extremely smooth surface which reduces air friction to a minimum. Still the product is very flexible, easy to work with, and resistant to delamination or working surface failure. |
