Abstract
An aircraft insulation product comprising a glass fiber blanket faced on at least one major face with an air permeable sheet. Insulating fibers coated with unbonded binder are directed to a web of the permeable sheet material supported on a moving collection chain, and the resulting fibrous layer and the web are sent to an oven where the binder is cured. The collection web thus becomes bonded to the blanket by the binder to become an integral part of the insulation product. A plurality of stacked blankets, the edges of which are covered by a film, may be used instead of a single faced blanket.
