Fibrous acoustic material must be separated from the air path.
The film liner adds a continuous barrier beneath the perforated facing.
A thin protective film separates the glass-fibre fill from the perforated air-facing metal. The curved passages still turn the duct through a right angle, while the film-lined construction addresses applications that require additional separation of the media from the airstream.
