  • Patent number: 7509980
    Abstract: The present invention relates to ventilation tubing comprising, from the inside to the outside, a bush (1), an insulating layer (2) and a cover sheet (3). Said ventilation tubing is characterized in that the insulating layer is a quartz fiber wool of which the specific surface weight illustratively is between 65 and 140 g/m2. The bush (1) and/or the cover sheet (3) may be a plastic sheet exhibiting a weave of interlacing filaments. In particular the present invention applies to aircraft ventilation circuit tubings.
